number are from the Firth of Clyde, the chief localities being 

 Ardrossan, Saltcoats, Arran, and Rothesay Bay; one species, 

 however, was obtained from Portencross, and another from 

 Cumbrae. 



The subjoined list from the Cumbraes includes ten genera and 

 thirty-seven species. Five of these are new to the West of 

 Scotland, viz. : — • Hermcea bifida, Eolis Feachii, E. concinna, E. 

 amoena, and E. cingulata. Regarding this last species, Mr Alder 

 writes (August, 18G6) — '^ Eolis cingulata, I am particularly 

 pleased you have met with, as the two specimens I got on our 

 coast, about twenty years ago, are all that I ever heard of till 

 now." 



Hero formosa is another of interest, as it is the second specimen 

 procured in Britain (1864). The first, a single specimen, had been 

 dredged the year before off Holy Island, Durham coast. 



I have been indebted to the late Mr Joshua. Alder and to Dr 

 Collingwood for their kind assistance in determining all doubtful 

 sj)ecies. A few specimens not in the hst died during their trans- 

 mission to these gentlemen ; one of these I beUeve to be Thecacera 

 pennigera, a rare species.
