Report on the Crustacea Schizopoda of Ireland. 227 
The numerous specimens of St. 144 were taken while theS.S. “Harlequin” was 
tending on some local boats engaged in experimental mackerel-fishing. Some 
mackerel were caught, but their food was not examined. 
Marine Laboratory.—4 miles west of High Island, Co. Galway, surface and bottom 
tow-nets at night, 16th June, 1899, and very common in stomachs of mackerel 
from surface drift-nets about the Bofin islands during the same month. 
No Previous Irish Record. 
Distribution.—Aberdeen ; Firth of Forth; Loch Seaforth (A. M. N.*): off 
Hebrides; mouth of English Channel (Ortmann). 
Norway ; Finmark; Siberia; N.E. America (A. M. N.*): Bay of Biscay 
(Caullery ). 
Genus—NEMATODACTYLUS, Calman. 
Nematodactylus boopis, Calman. 
Cauman, Trans. R. I. Acad., xxxi., 1896, p. 17, Pl. 11. 
Off S.W. of Ireland, 1020 fathoms (Calman). 
The species is not definitely British, as Norman’s limit is the 1000 fathoms line. It is mentioned here 
for purposes of convenience, 
Genus—EUCOPIA, Dana, 
Eucopia australis, Dana. 
Caiman, Trans. R. I. Acad., xxxi., 1896, p. 15. 
Off S.W. of Ireland, 1020 fathoms (Calman). 
This is a cosmopolitan species from the deep water of the oceans; Calman considers that its occurrence 
at or near the surface must be regarded as exceptional. It has not yet been taken actually within the 
limits of the British area. 
Family.—MYSIDZ&. 
Sub-family.—S1rreLLin z. 
Genus Siriella, Dana. 
Siriella Clausii, G. O. Sars. 
Not in the Survey Collection. 
Marine Laboratory.—Blacksod Bay, 29th March, 1899, 6-8 fathoms; Inisbofin 
Harbour, 4th to 18th August, 1899, very common in surface and midwater nets at 
night, but not found, perhaps on account of abundance of drift-weed, during the 
day. 
Previous Irish Record.—S.E. of Ferry pier, Valentia Harbour (A. O. W.*) 
Distribution.—Loch Fyne (A. M. N.*): off Plymouth.t+ 
Mediterranean (A. M. N.*). 
+ A Siriella of rather abnormal character, from Start Bay, is also probably referable to this species.
