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 strise — 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.

determination to publish a " Synopsis of the Birds of the 
United States." Part of this, including the first three orders, 
has already appeared in the Annals of the Lyceum of Natu- 
ral History of New York. But as circumstances beyond our 
i'ontrol are likely to delay for several months the publica-
