size than those described by Morelet, and Fischer and Crosse, 

 viz: Specimen from Peten, whorls 9-10, length 12-13, diam. 

 3;' aperture long. 2^, ddam. I 1 /) millim.; specimen from Liv- 

 ingston, whorls ll 1 /^, length 15, diiam. 3y 2 ; aperture long. 3, 

 diam. l 1 /^ millim. Nevertheless, the specimens from Living- 

 ston agree so well with Fischer and Crosse 's figure of Subu- 

 lina lirifera that I do not think they can be separated, not 

 even as a variety. The very concave shape of the columellar 

 margin gives the species somewhat the facies of Tornaxis."

The rib-stria3 are a little more spaced than in berendti, and 

 the columella is less distinctly truncate. Length 14, diam. 3, 

 aperture nearly 3 mm. ; whorls 12. The largest shell is 15 

 mm. long with 12 whorls.

Shell cylindric-turrite, rather solid, closely plicate, some- 

 what glossy, subdiaphanous, whitish-waxen. Spire subregu- 

 larly tapering, rather obtuse ; suture subcrenulate. Whorls 

 12, the upper very convex, the following natter, last whorl 

 scarcely one-fifth the total length, rounded below. Colu- 

 mella short, slightly arcuate, obliquely truncate. Aperture 

 suboblique, elliptic-oval; peristome simple, the right margin 

 slightly arched forward. Length 13, diam. 3, aperture 2.66
