After No. 235, Tornatellina Cuhensis Pfr., should be in^ 

 serted. 



Aftei No. ^85, Helix Schroeteriana Pfr., should be in- 

 serted. 



No. 294 a may be elevated to the rank of a species, with 

 the name Helix pretiosa. This name was used by Ferussac 

 for a species of Achatina, A. Peruviana. It is however, in ac- 

 cordance with the usage of many, still admissible for a true 

 Helix. Another name certainly would have been preferable, 

 had not the present name been used by us already to distin- 

 guish the type as a variety. 



No. 38"4. The name Ancylus obliquus having been antici* 

 pated by Mr. Broderip for a Chilian s| ecies, Proc. Zool. Soc. 

 Lond., 1832, p. 202, we propose for this Jamaica species the 

 name of A. Chittyi, in honor of its discoverer. 



Mr. Redfield informs us that in the September number of 

 Reeve's Conch. Icon., which has not yet been received here, 

 (Amherst), Helix incerta and H. lima, regarded by^ Mr. 

 Reeve as one species, are said to inhabit Jamaica. It is well 

 known to collectors in this country that H. lima inhabits 

 Porto Rico, and that H. incerta comes from St. John's, near 

 St. Thomas. AVe are confident that neither of them inhabits 

 Jamaica. 



In the same number of the Iconica, the habitat of Helix 

 angustata is said, on our authority, to be Jamaica. "We have 

 before remarked (p. 177,) on what authority this species was 

 included in the catalogue of Jamaica shells, although we have 

 never seen it in Jamaica ; and since it is said to occur both in 

 Hayti and in Jamaica, it is not improbable that it inhabits 

 Hayti only.
