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

 fatigiata Say, or Hazardi Nob. (plicata Say). 



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

 ana, and to which Shuttleworth refers in his observations on H. fatigiata 

 (see ante, p. 286), appear to represent an undescribed species from 

 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. W. G. Binney. One from Tamaulipas has the rufous baud on 

 the periphery, agreeing with Pfeiffer's Yar. y.

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

 States, and I subjoin a copy of it: —

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

 lique wrinkles or stria3 ; suture deeply impressed ; epidermis smooth, and 

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