not mentioned in Pfeiffer's description. 



Strophia iostoma, Pfr. Mr. Sargent found very large specimens at 

 Great Inagua. 



Choanopoma occidentale, Pfr. Referred by Pfeiffer to Martinique, 

 but according to M. Maze does not occur there. Dr. V. 

 Rijgersma found it several years ago in the Island of St. Martin. 



Helix Ammonoceras, Pfr. Discovered in 1851 in New Granada 

 by Mr. Bland; since found in the Island of Grenada, W. I. 



Helix Hubbardi, A. D. Brown. Found originally in Texas by 

 Mr. Hubbard and described by Brown. It was subsequently 

 discovered in Jamaica and described by C. P. Gloyne as 

 Helix Vendryesiana. Dr. Newcornb has found it in Georgia. 

 It is allied to H labyrinthica, Say, and not to H. paludosa. 

 The distribution of H. Hubbardi is curious, but H Strebeli, 

 Pfr., which is perhaps identical with labyrinthica, belongs to 

 the Mexican fauna. 



Helicina nemoralis, Guppy, from Trinidad, is scarcely distinct from 

 H columbiana, Phil., of Venezuela. 



A uricula pellucens, Menke. A few dead specimens were found at the 

 edge of a Mangrove swamp on a small Island on the West 

 Coast of Florida, in company with a profusion ol Melampus 

 bidentatus and M. coniformis. A. pellucens is referred to 

 Demerara, and Ellobium Ceylanicum, H. & A. Ad., placed in its 

 synonymy by Pfeiffer, to Ceylon. Stimpson refers to the pres- 

 ent tropical character of the shells of the West Coast of 

 Florida as due to the influence of the Gulf Stream.

The author, in company with Prof. Harper, has collected 

 these Shells extensively at their head-quarters in many parts of 

 Kentucky and Tennessee. The great and unusual facilities they 

 possessed enabled reliable observations to be made on the habits
