Salasiella minima PILS., Proc. A. N. S. Phila. 1903, p. 773, 

 fig. 6. 



This smallest species -of the genus is not unlike 8. modesta 

 in shape, 'but it is built on a much smaller scale. For com- 

 parison I figure a young specimen of S. modesta, the different 

 contour of which may be readily appreciated. 



5. S. PERPUSILLA (Pfeiffer). Figures 2, 3, page 171. 

 Manual, vol. I, p. 43. This species is more convex below 



the suture than S. modesta, minima, or subcylindrica. The 

 figures here given represent specimens from Diente, the orig- 

 inal of fig. 3 measuring, length 3.3, diam. 1.4, length of aper- 

 ture 1.9 mm. 



Guatemala (Stall) ; Mirador and Jalapa, State of Vera 

 Cruz, and Diente, near Monterey, State of Nuevo Leon. 



6. S. PULCHELLA (Pfeiffer). PI. 28, fig. 62.

 to be arcuately and irregularly striatulate, glossy, corneous- 

 whitish, obsoletely streaked with buff. Spire convexly conic, 

 rather acute, with a narrowly margined suture. Whorls 6, 

 moderately convex, the last scarcely two-thirds the total 

 length, somewhat tapering basally. Columella somewhat 

 straightened, narrowly truncate. Aperture vertical, sinuate- 

 semioval, long-acuminate ; peristome simple, the right margin 

 slightly dilated forward. Length 10.5, diam. 3.75, aperture
