Hills around Orizaba, about 500 feet above the town. Type No. 

 58,070, A. N. S. P., collected by Witmer Stone, of the Heilprin expedi- 

 tion of 1890. 



This smallest species of the genus is not unlike S. modcsta in shape, 

 liut it is built on a much smaller scale. For comparison I figure a 

 young specimen of *S. modcsta, the different contour of which may be 

 readily appreciated. 

 Salasiella subcylindrica n. sp. Fig. 1. 



Shell distinctly cylindric, the rather long spire tapering to an obtuse 

 apex; corneous-white; smooth except for a few impressed lines fol- 

 lowing the direction of growth-lines. Whorls 4f , slightly convex, the 

 last flattened peripherally. Suture margined by transparence. Aper- 

 ture of the usual shape ; outer lip strongly arched f orw^ard in the mid- 

 dle, retracted above and below. Columella as in other species of the 

 genus. Length 5.6, diam. 1.8, length of aperture 3.15 mm. 



Diente, near Monterey, State of Nuevo Leon. Types No. 77,169, 

 A. N. S. P., collected by S. N. Rhoads, 1899. 



This species is larger and more cylindric than S. modcsta, and the 

 columella is less concave. Its contour is quite unlike that of S. perpu- 

 silla, which also occurred at Diente. 

 Strebelia berendti (Pfr.). 



Texolo, State of Vera Cruz (Rhoads, 1899).

Diente, near Monterey, Nuevo Leon. Types No. 77,153, A. N. S. P. 

 It is rather abundant, and the locality is far to the north of any 

 former record for the genus, 

 streptostyla edwardsiana C. and F. 



Texolo, Prov. Vera Cruz (Rhoads, 1899). 



Mr. Ancey has recently added two more sjDecies of this genus, *S. 

 sumichrasti and S. clavatula.*
