S Bonaparte's Catalogue of the 



Note. — In the same locality where the S. Jeffersoniana 

 was found, I also observed a new species of Helix, of which 

 the following is a description: 



Helix Pennsylvanicus. — Shell subglobose — spire eleva- 

 ted — whorls six or seven, with numerous oblique wrinkles 

 or striae — sutures deeply impressed — epidermis smooth and 

 of an olive brown colour like most of the American Heli- 

 ces — umbilicus closed or masked — aperture slightly con- 

 tracted at the base — a small callosity on the inner margin 

 of the other lip, near its lower angle — shell rather more 

 than half an inch in diameter. 



This shell somewhat resembles the H. Clausa of Mr. Say, 

 but may very readily be distinguished from that species by 

 the closed umbilicus, the number of its whorls, and its gen- 

 eral form. 



This shell is not uncommon in the moist ground near 

 Chartier's creek, in Washington county, Pa. I obtained 

 five or six specimens with but very little trouble at that 

 locality^ associated with the H. Solitaria, Profunda, and 

 Paliata.

The following catalogue was originally drawn up for the

 determination to publish a " Synopsis of the Birds of the 

 ( Fnited States." Part of this, including the first three orders, 

 has already appeared in the Annals of the Lyceum of Natu- 

 I History of New York. But as circumstances beyond our
