1900. Dasymysis longicornis, Holt & Beaumont, 1. c. p. 25. 



Found in some abundance in Start Bay^ S. Devon, at the 

 end of July 1898. It was taken on fine gravel and sandy 

 ground off Blackpool and Slapton Sands, in from 5-8 fathoms, 

 in company with Mysidopsis gibbosa and M. anyusta (Holt fy 

 Beaumont, v. p. 344); also recorded by the same naturalists 

 from off Plymouth. Messrs. H. & B. thought and had 

 reason to think that A. longicornis was an addition to our 

 fauna when found by them ; but by a curious coincidence, 

 only one month before, on June 10, 1899, it was taken in a 

 bottom tow-net in 20 fathoms at Bull Bay, Anglesey, by 

 Mr. A. 0. Walker.

 from the Cornish coast " where the bottom is rocky, with 

 some spots of sand/' 



SQUILLA DESMARESTII, Risso. 



The first British specimen was obtained from the Cornish 

 coast by Mr. Couch, and A. M. N. has received others 

 procured by Laughrin at Polperro about forty years ago.
