DESCETPTION and NOTES of some NEW and BAKE 

 COPEPODA from LIVEEPOOL BAY. 



By Mr. Andrew Scott. 



FISHERIES ASSISTANT, UNIVERSITY COLLEGE. 



With Plates I. to V. 



[Read March 13th, 1896.] 



The copepoda which form the subject of the following 

 notes were obtained by washing dredged material, trawl 

 refuse and mud collected in various parts of the L.M.B.C. 

 area by Professor Herdman, Dr. Hanitsch and myself 

 during the past year and latter part of the previous year 

 (1894) while on expeditions to the dredging grounds, 

 trawling stations and mussel beds. They are all additions 

 to the fauna of Liverpool Bay and may form a useful 

 appendix to the valuable papers published by Mr. I. C. 

 Thompson, F.L.S. 



Family Harpacticllle . 



Sunaristes paguri, Hesse. 



This rather peculiar and interesting species was obtained 

 by washing the shells of Buccinum inhabited by the 

 hermit crabs Pagurus bemhardus, collected in the trawl- 

 net of the steamer while working at the mouth of the 

 Mersey estuary on the 23rd of July, 1895. It seems to be 

 a comparatively rare species and so far as is known this 

 is only the third time it has been found in British waters. 

 From our present knowledge of its distribution it appears 

 to be confined to areas having large volumes of brackish 

 water passing over the bottom, and has not been found in 

 pure sea- water. 



Sunaristes paguri is not unlike Canuella perplexa in 

 general appearance but is readily distinguished from that 

 species by the structure of the various appendages, 

 especially the antennules and second pair of swimming 

 feet of the male.
