 species of Bullcea^ Lam. ; and on some species of the 

 Annelida, Bi/ William Clark, Esq. 



[To the Editor of the Zoological Journal.] 

 S1R5 



During my residence at the sea side, in the Summer 



months, I have employed my leisure time in forming a collection 

 of British Shells, and in examining the animals inhabiting them. 

 To obtain them I engaged an expert dredger, and by this means 

 I have procured nearly the whole of our marine indigena in a living 

 state, recovered many long lost species, and added some new ones 

 to our catalogues. Perhaps the following observations and descrip- 

 tions of some of the animals of the genus Bullcea, which are 

 found in our seas, and which I believe have never before been 

 observed by any writer on this subject, as well as a few brief 

 references to some other marine animals, may be considered in- 

 teresting to those who have turned their attention to this branch 

 of natural history, and particularly to the collector of our native 

 Testacea. If this should be your opinion, you are at liberty to 

 make any use of them you may think proper. 

 I am, Sir, 



Your obedient servant, 



William Clark.
