(«.)• 



Porcellidium fimbriatum, Claus. — Loch Fyne and East Loch Tarbert 

 (Calderwood). Upper Loch Fyne, near Largabruach, and near the head 

 of the loch (G.). 



Porcellidium subrotundum, Norman. — Upper Loch Fyne, in 30 fathoms 

 (M.). 



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 (G.). 



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 3 of Laminaria and other large marine 

 algae. 



Monstrilla (?) Danx, 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 setae,' 

 which are united at the base so as to form a very short but quite distinct 

 basal part ; the caudal setae 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 Danse, Claparede, in Mr Bourne's memoir on the MonstriU 

 lidai* The fifth feet, so far as I can make them out without dissection, 

 resemble those of Monstrilla gracilicauda, Giesbrecht. 



Parasita. 



Lichomolgus fucicolus, G. S. Brady. — Upper Loch Fyne, near Larga- 

 bruach, in dredged material (G.). 



Lichomolgus forficulus, Thorell. — In the branchial chamber of large 

 Ascidians from Loch Fyne and East Loch Tarbert (Mihi). 



Lichomolgus furcillatus, Thorell. — Off Inveraray, Upper Loch Fyne, 

 from trawl refuse (G.).
