26 LEPTACHATINA, GROUP F. 



Gulick 's, for granifera are: Length 7.0, diam. 3.3 mm.; 

 length of body whorl 4.5 mm. 



I have followed Mr. Sykes in referring Pfeiffer's and. 

 Gulick 's species to accincta. Unfortunately Mighels's type is 

 probably lost as no trace of it could be found. The figure in 

 the U. S. Exp. Exped., Moll., pi. 7, fig. 97, belongs to an en- 

 tirely different species, L. ventulus Fer. 



31. L. CRYSTALLINA (Gulick). PL 3, fig. 50. 



" Shell dextral, imperf orate, oblong, thin, shining, trans- 

 parent, vitreous, microscopically very finely striated; apex 

 somewhat obtuse ; spire convexly conical ; suture simple, mod- 

 erately impressed; whorls 6, somewhat convex; columellar 

 fold central, corneous, but slightly developed; aperture ro- 

 tundately lunate; peristome simple, bordered with white; 

 with dextral margin unreflected, arcuate; columellar margin 

 dilated. Length 6.0, diam. 3.0, length of body whorl 4.0 

 mm." (Gulick.)

A small ovate species related to the shells referred to 

 L. accincta Mighels, but more slender, with a less conical 

 spire, and with a more perpendicular and narrower aperture. 

 A specimen in the collection of the Academy of Natural 

 Science of Philadelphia, no. 91807, has the following meas- 

 urements: length 6.6, diam. 2.9, length of apert. 2.8 mm.
