figure (Plate ix. fig. 33), and also Reeve's figure (same plate, fig. 34), 

 which fairly represents the species, 



H. Texasiana, in the form of the aperture and teeth, is nearly allied 

 to II. Hindsi Pfr., and certainly more to U. ventrosula Pfr. than to H. 

 Jatigiata Say, or Iluzardi Nob. [i^licata Say). 



The figures in Chera. (ed. 2, 1. 10, fig. 11-12) said to be of H. Texasi- 

 ana, and to which Shuttleworth refers in his observations on ^./«%^ato 

 (see ante, p. 28G), appear to represent an undescribed species fi'om 

 Louisiana, of which I have specimens from the cabinet of Dr. Binney, 

 and also from Mr. Isaac Lea. 



In my cabinet there are numerous specimens of H. Texasiana Mor. 

 from Texas and Mexico, — received from Judge Tappan, Dr. Newcomb, 

 and Mr. AV, G. Binney. One from Tamaulipas has the rufous band on 

 the periphery, agreeing with Pfeifi'er's Var. y.

Green's description is not readily met with, even in the United 

 States, and I subjoin a copy of it: — 



"H. PENNSYLVANICUS. 



Shell subglobose ; spire elevated ; whorls 6 or 7, with numerous ob- 

 lique wrinkles or strise ; suture deeply impressed ; epidermis smooth, and 

 of an olive-brown color, like most of the American Helices ; umbilicus
