Microniscus. The little parasite known by this name, and which, in 

 the tow-net gatherings of the " Garland," is sometimes found clinging to 

 Calcmus, Pseudocalanus, and other Copepods, has just been shown by 

 Prof. Sars ("Crustacea of Norway," vol. ii., p. 218-220, 1898) to be one 

 of the post-larval stages of a species of Phryxus. In my paper on the 

 "Marine Fishes and Invertebrates of Loch Fyne," published in the 

 Fifteenth Annual Report of the Fishery Board for Scotland (p. 136, 1897), 

 attention was directed to the close resemblance between Microniscus and 

 the young of Phryxus ftisticaudatus, Spence Bate, but no definite opinion 

 was expressed as to the relationship between them. Probably more than 

 one kind of Bopyrus is represented by these Micronisci, but it may, at 

 this stage, be difficult to distinguish the one kind from the other. 



Cumacea. 



Several interesting Cumaceans have been observed during the examina- 

 tion of tow-net gatherings recently collected, the following of which may 

 be referred to : — 



Lamprops fasciata, G. 0. Sars, has been obtained sparingly in a 

 gathering from the Cromarty Firth. Hemilamprops rosea, Norman, 

 occurred in a gathering from Station IV. (Kilbrennan Sound), Firth of 

 Clyde. Leucon nasicus, Kroyer, was obtained in a gathering from 

 Station XII. (Firth of Clyde), depth 40-43 fathoms. Eudorellopsis 

 deformis (Kroyer) — a curious little Cumacean — was taken at Stations 

 VII. and VIII., Firth of Clyde, in moderately deep water. Eudorella 

 truncatula (S pence Bate) occurred in gatherings from Clyde Stations 

 VII. and VIII., and Eudorella marginata (Kroyer) in a gathering from 

 Station XII. 



Campylaspis rubicunda, Lillejeborg, was obtained in gatherings from 

 Clyde Stations XII. and XVII. Cumella pygmcea, G. 0. Sars, occurred 

 in a gathering from Station IV. (Kilbrennan Sound), Firth of Clyde, 

 24th August 1898, and in one from Station XV. Moray Firth, 15th 

 November 1897. 



Cuma pulchella, G. 0. Sars, though only recognised within recent 

 years as a member of the British fauna, has apparently a wide distribution 

 around our shores. It was obtained in the Firth of Forth in 1889-90, 

 and recorded in Part III. of the Eighth Annual Report of the Fishery 

 Board for Scotland, p. 329, and afterwards in the Liverpool Bay District 

 (Eighth Annual Report of the Liverpool Marine Biological Committee, 

 p. 25). I have now to record its occurrence in the Clyde, having ob- 

 tained one or two specimens in some washings of dredged material from 

 Station VI. As pointed out by Dr. Norman, the first joint of the seventh 

 foot is furnished with a series of backward-directed tooth-like processes, 

 by which character C. pulchella may be distinguished from its congeners. 



Schizopoda. 



The Schizopoda, though plentiful in some of the gatherings, were 

 usually limited to a few species, amongst which the Euphausiidse were 

 the most numerous. The Schizopod usually of most frequent occurrence 

 in the Clyde and Loch Fyne gatherings is Boreophausia raschii, but in
