soon died"^. The specimen, ])reserved in spirit, I am about to 

 deposit in the British Museum. 



I wish to dedicate this genus to the venerable author of ' A 

 History of the British Stalk-eyed Crustacea,' to whom I per- 

 sonally owe a life-long debt of esteem, and gratitude, and lovef. 

 And the species to the friend to whom science is indebted for 

 its fortunate discovery.

XXXIX. — On Hancockia eudactylota, a Genus and Species of 

 MoUusca, supposed to be neu\ By Philip Hexky Gosse, 

 F.E.S. 



[Plate XL] 



Family Tritoniadse. 



Hancockia (gen. nov.), Gosse. 



Body linear, scarcely palliate. 



Head, beneath, produced on each side into a broad, flat, 

 many-fingered oral tentacle. 



Dorsal tentacles two, with laminated bulbs, retractile within 

 sheaths. 



Branchiffi three pairs, foliate, pinnatifid, infolding, remotely 

 seated on the subpalliate margin of the back. 



Foot linear, grasping. 



HancocJda eudactylota^ Gosse. 



The only known species. 



Body (a, h) about half an inch in length when crawling, 



* My friend favours me with the following note : — " BeUicJia is doubt- 

 less a rocky shrimp, not a sandy one ; and "its colours would match the 

 beautiful red weeds among which it is found. I believe it was oft" a mass 

 of red weed that I picked the Hancockia (see the following memoir), 

 and the veiy minute Aplysia found on the same occasion, which I after- 

 wards showed you."' 



t 1 had at first written the word as " Bellia ;" but I find that this 

 fonn is already occupied in zoology. As I do not choose to relinquish 

 my tribute of afifection to my fiiend, I adopt another termination.
