description of the species by Dr Brady in the Fifth Annual Report of the 
Fishery Board for Scotland.) Near Largabruach, Upper Loch Fyne 
(G.). | 
Porcellidium fimbriatum, Claus.—Loch Fyne and East Loch Tarbert 
(Calderwood). Upper Loch Fyne, near Largabruach, aud near the head 
of the loch (G.). 
Porcellidium subrotundum, Norman.—Upper Loch Fyne, in 30 fathoms 
Idya furcata (Baird),—East Loch Tarbert (Calderwood). Upper Loch 
Fyne, near Largabruach, and off Inveraray (G.). 
Idya longicornis, T. and A. Scott.—East Loch Tarbert, Loch Fyne 
(Mihi). This is a large and well-marked species. 
Idya gracilis, T. Scott. —This was obtained in Loch Gair, off Inveraray, 
and near the head of Loch Fyne iG.) 
Idya minor, T. and A. Scott.—Upper Loch Fyne, near Largabruach, 
and near the head of the loch (G.). 
Scutellidium fasciatum (Boeck).—East Loch Tarbert (Calderwood). 
Obtained by washing the ‘roots’ of Laminaria and other large marine 
alge, 
Monstrilla (?) Danze, Claparede.—A single representative of this curi- 
ous group of Copepods was obtained in a bottom tow-net gathering col- 
lected between Dunderave and Ardno, near the head of Loch Fyne (G.). 
The specimen is a female, and has three abdominal segments. . The first 
segment is about twice as long as the second, and is more tumid ; it is also 
rather longer than the third segment ; it bears two long ‘ genital sete,’ 
which are united at the base so as to form a very short but quite distinct 
basal part ; the caudal sete are three on each furca. The antennules are 
in length scarcely equal to one-third the length of the body ; the first joint 
is about four and a half times the length of the second, the third is about 
one and a half times the length of the second, and the second and fourth 
joints are nearly equal in length; the antennules are four-jointed. The 
Loch Fyne specimen thus agrees very well with the brief description of 
Monstrilla Danz, Claparede, in Mr Bourne’s memoir on the Monstril- 
lide.* The fifth feet, so far as I can make them out without dissection, 
resemble those of Monstrilla gracilicauda, Giesbrecht. 
PARASITA.

bruach, in dredged material (G.).
