 tacea. In one case, Edward caught only the anterior 

 moiety of a small Crustacean (Protomedeia Tiirsuti- 

 mana), and yet Mr. Bate includes it in his list, and 

 gives a drawing of it. Mr. Bate also did every justice 

 to the accurate, description of the habits of the species 

 which Edward forwarded to him. Eor instance, 

 Edward discovered the Vibilia lorealis, a new 

 species, in the Moray Firth, on which Mr. Spence 

 Bate observes 



" Hitherto the species of this genus have been 

 taken only as pelagic, in tropical or sub-tropical lati- 

 tudes. It is an interesting fact that this species 

 should have been taken off the coast of Banff, from 

 whence it was sent us by that very successful ob- 

 server Mr. Edward, who, in writing, says : ' I can 

 say little as to its habits. I took eleven, and kept a 

 few alive for a short time, but observed nothing in
