although surprisingly small amounts can be utilized; heathers, bramble, bushea.
hedges, ditches, drains and stone piles can all afford concealment. With the abundance of such sites available in Northern Ireland, the foxes proven ability to
make use of them, the mild climate and the animal's thick insulating coat of hair, this lying up above ground is not surprising. The idea that foxes hunt at night and
sleep in earths during the day is a gross oversimplification. It is not until December the heterosexual pairs are particularly noticeable.
By this time the typical vulpine odour is becoming more apparent. Foxes
copulate in January and early February (unpublished data). In February and, exceptionally, late in January there is frequent evidence
that the animals are digging at the earths. Copious fresh soil is scattered around
the mouths of holes and this is marked with foot-prints. It is not uncommon for a dropping to be deposited in the entrance. It is in February and March that foxes smell most strongly. This is not only remarked by hunters but is very noticeable
while dissecting carcasses. While handling live foxes, during tagging studies, they were particularly restless and difficult to handle at this time. All this suggests that
perhaps there may be some sort of territorial behaviour with respect to an earth.
Surprisingly small holes, unoccupied at other seasons, may show signs of fox
activity, but some holes which seem satisfactory are not occupied. As the vixen nears term she remains below ground and the dog fox lies
in nearby cover, or, less commonly, in the mouth of the burrow during the day.
During late February and March they are thus more easily killed. It seems likely that the activities of the vixen are restricted to a small range in late pregnancy. It is probable that she may hunt a fortnight before parturition but in the later
stages the dog fox carries food to her. Judging by one accumulation of prey this
can be considerably in excess of her immediate needs?one earth containing a
vixen almost at term had a complete domestic hen, a pullet and half a rabbit.

UNPUBLISHED RECORDS OF MARINE ALGAE MADE MAINLY IN COUNTY WATERFORD BY THOMAS
JOHNSON AND MATILDA KNOWLES
M. J. P. SCANNELL
The coast of County Waterford, H 6, is long and varied yet few marine
algae have been recorded from its shores. A recent bibliography of phycological literature (Dixon, Irvine and Price, 1966) lists four papers for the county. The
most important is that of Johnson (Anon., 1897, pp. 139-140) who, as secretary of the Dublin Naturalists' Field Club, reported the activities of the Club for the
year 1896. Johnson incorporated in the report a summary of a paper by himself
and Miss Matilda C. Knowles which he had read at a meeting of the Club.

of the Herbarium, Science and Art Museum, Dublin, with A. R. Nichols, a marine
zoologist, visited Dungarvan in October 1896 to collect marine algae and shells
on behalf of the Flora and Fauna Committee of the Royal Irish Academy. This
Committee had been set up in 1893 to encourage biological field work in Ireland.
The paper read by Johnson was based on Miss Knowles' identification of the
specimens collected chiefly at Helvick Point. It was stated in the summary that 90
species had been collected and 21 are listed. In papers published by Johnson
(Johnson and Hensman, 1899, and Johnson et alia, 1899) a further nine species are recorded, making a total of 29 species published. Batters (1902) includes a total
of 16 records from both Dungarvan Bay and Helvick Point. His records of
epiphytic Phaeophyceae may have been extracted from Johnson's paper but records of Chlorophyta and Rhodophyta seem to have been communicated directly to
Batters by Johnson. In 1896 Miss Knowles was a student of Johnson in the Royal College of Science. Of the other papers referred to in the bibliography (Dixon, Irvine and Price, 1966), Parkes (1953) mentions the work of Miss Ann Ball
(referred to by Harvey in Mackay, 1836, as "an acute and zealous algologist") who lived at Youghal, Co. Cork, and recorded algae from Ardmore, Co. Waterford.
Brennan (1945) records Callymenia reniformis from the county but gives no locality. The fourth reference in the bibliography is to the donation by Johnson of
specimens to Herbarium TCD (Anon., 1898), The following aspects of the history of the algal flora of Co. Waterford
may be of interest here. The Ring district of the county, on the south shore of
Dungarvan Bay, was one of the areas on the south coast heavily denuded of seaweeds in pre-famine years due to the use of seaweed as a manure for the potato crop (Lewis, 1849). The Reverend Eugene O'Meara visited the county prior to
1875. He collected diatoms from the larger seaweeds at Tramore, publishing his
results in his major work on the Irish Diatomaceae (O'Meara, 1875). Harvey (in
Mackay, 1836, pp. 182, 241) includes two records from H 6, Ectocarpus tomentosus
Lyngb. from Ardmore, collected by Miss A. Ball, and Porphyra linearis Grev.
collected at Dunmore by Miss A. Taylor. There is a specimen of the last mentioned
seaweed in Herbarium DBN, collected by Thomas Chandlee, but no date is given. A recent addition to the algal flora of the county, Melobesia jarinosa
Lamour, was recovered from leaves of Zostera angustifolia collected by Dr Keith
Ferguson, Herbarium, Royal Botanic Gardens, Kew, on salt marsh, Back Strand,
Tramore, on 18th August, 1968, and donated to Herbarium DBN.
The list of seaweeds collected at Dungarvan in 1896 by Johnson was
never published in full. In 1968 a six-page manuscript in the handwriting of Miss
M. C. Knowles was uncovered in the Herbarium amongst papers relating to algae. The list is entitled "Marine Algae from South East of Ireland" and it is a
record of specimens collected between 1895 and 1896. The records are mostly from Helvick Point, the extremity of an easterly facing promontory south of
Dungarvan Bay. Included in the list are records, also, of 9 species from Ballina
courty on the north side of Dungarvan Bay and a small number of species from
other localities in Ireland. Many records from numbered districts are included.
The numbers refer to the divisions of the coast of Ireland proposed by Holmes
and Batters (1891) and adopted by Johnson (Johnson et alia, 1899). The district
divisions are as follows: 10. Malin Head, Co. Donegal, to Slyne Head, Co.
Galway; 11. Slyne Head to Crow Head, Co. Cork (W); 12. Malin Head to Howth,
Co. Dublin; 13. Howth to Raven Point, Co. Wexford; 14. Crow Head to Raven
Point. Initials follow the district numbers and refer to the collector as J for

Johnson, H for Hensman and K for Knowles. In the case of Sorocarpus uvaeformis the statement R 11 would seem to refer to Roundstone, district 11 (see Johnson's
paper on the Phaeophycea). The Knowles list follows the order of the major groups of algae
Cyanophyceae, Chlorophyceae, PhaeopHyceae and Rhodophyceae in Holmes and
Batters (1891). The species do not follow the order within these groups. This
may be due to the fact that the manuscript list was a working document and was
not intended as the final draft. The nomenclature agrees, in the main, with that
of Holmes and Batters (1891) with the exception of the genera Streblonema and
Ectocarpus. Johnson was in communication with M. Sauvageau regarding the nomenclature of the Irish parasitic PhaeopHyceae (Johnson et alia, 1899). Authors are cited in some cases only. When authorities are quoted they follow, in the
main, those of Holmes and Batters (1891). Synonyms, when such could be traced in Parke and Dixon (1964), are given in parenthesis. Miss Knowles has distin
guished in the manuscript list those specimens which are previously unrecorded
either from Ireland or from district 14. These records are indicated respectively below thus *, t
A search has been made for the material collected in the Dungarvan area
in 1896. A total of 14 specimens has been located in Herbarium DBN. Some
material was donated to Herbarium TCD by Johnson (Anon., 1898, p. 122).
Micropreparations of algae, referred to by Knowles, have not been found.
Specimens located in Herbarium DBN are so noted in the list published below.
For convenience of reference, species are arranged in alphabetic order
within the classes and in this matter is a departure from the manuscript of
Knowles. A sketch map is included to show the location of Helvick Point and
Ballinacourty in County Waterford. The Irish National Grid references are: ?

THE SPREAD OF FERAL MINK IN IRELAND C. Douglas Deane and Fergus O'Gorman
The American mink, Mustela vision Schreber, is found throughout Canada and United States wherever suitable habitat exist. It is semi-aquatic and although more terrestrial than the otter, is fast-moving and swims efficiently
having partially-webbed toes. It is rarely found far from water where it feeds on
crayfish, mussels, fish, birds and small mammals. It climbs readily and has been seen 50 feet (15 metres) above the ground.
The male is considerably larger and heavier than the female and the anal
glands, characteristic of weasels, are well developed and pungent in this species. The pelage is composed of long, hard, lustrous hairs with a short undercoat of
soft, dense fur, dark brown in colour, but lighter in tone than the long hairs, sometimes with a more or less white chin.
In captivity it is used as a ferret and is bred extensively for the sake of
its pelt. In the late 1920s ranch-bred mink were exported to various countries
including Britain and Scandinavia and by 1959 the world population of captive mink was between 10 and 11 millions (Thompson, 1968a).
The carefully selected ranch bred mink is far removed from its wild
ancestor and combines large size and fertility with the excellent pelt quality of the
eastern form, resulting in a blend of mutations ranging in colour through different shades of brown, beige, blue, grey, cream and white. Some two dozen
mutations have been developed, affecting colour and although the mutant may be
smaller, of reduced fertility and more susceptible to disease, current fashion and
colour preference can ensure its commercial success. Mink fur is prime from
November and may be taken until March when it is shed for a lighter coat.
The first fur farms for mink were established in Britain in 1929 and a
boom in demand provided a stimulus for considerable investment in breeding animals. The first mink farms in Ireland were established 1950-53 and the
result of a questionnaire survey in 1960 showed that over 40 people were breeding mink while the average unit size was 50 females and 20 males with pelt production at 4,000-4,500 skins (Dawczewski, 1960). According to various sources Ireland
is well suited for the fanning of mink as those bred in cold climates give a long, loose, woolly fur difficult to work, while the short, napped, close furred pelt obtained in humid, mild climates such as Ireland, is well suited for production of
good quality pelts.
