154 Catalogue of the Mollusca of Staten Island, N. Y. 



ever, still had the animal' in them. They were taken at first 

 for specimens of Saxicava, which they greatly resemble. The 

 ordinary varieties of this species are abundant on the Island. 



Martesia Smithii. An oyster shell dredged somewhere 

 around Staten Island contained a specimen of this shell with 

 the fresh animal, showing that whether an imported species or 

 not, it is at present living on our shores. 



Of Pupa rupicola only two specimens have been found. 



Helix striatella and H. suppressa have hitherto been found 

 in one locality only for each, but the first-named is there some- 

 what abundant. Of H. hirsuta one specimen only has occur- 

 red, near New Brighton, on the north shore of the Island. H. 

 chersina is scarce, not more than a dozen specimens having 

 been found. H. laoyrinthica is exceedingly abundant in one 

 locality. 



Succinea aurea is plentiful on the salt marshes. 



Of Tebennophorus Caroliniensis I have found only one speci- 

 men, at New Brighton. 



The list here given is probably by no means complete, espe- 

 cially as to the fresh-water shells, and some of the marine 

 species living in deep water. Our dredgings have been but 

 partial, and principally on mud bottoms. I hope hereafter to 

 be able to furnish a more complete catalogue, with full notes 

 on depth, habits, etc.
