PUPISOMA. 35 



haps a trifle more open. It appears to be a form of orcula. 

 Hedley 's line figures are copied. 



14. Pupisoma vimontianum (Crosse). PI. 3, fig. 13. 



Shell having an almost wholly covered umbilical crevice, 

 oval-conic, marked with minute, oblique, very fine striae, vis- 

 ible only under a lens, thin, but little shining, translucent, 

 clear corneous. Spire convexly conic, the summit obtuse. 

 Suture well marked. Whorls 4, convex, the last rounded, 

 nearly as long as the spire. Aperture subvertical, rounded- 

 semilunar, inside colored like the shell. Peristome simple, 

 with converging margins; columellar margin short, straight, 

 reflected, almost wholly covering the umbilical crevice, whit- 

 ish; basal and outer margins rounded and sharp. Height a 

 little less than 2, greatest diam. 1% mm.; length and width 

 of the aperture % mm. (Crosse).

 Not known to me by specimens. Compare P. orcula. 



15. Pupisoma steudneri (Jickeli). PI. 2, figs. 6a-d. 



The imperforate conic-globose shell is of a somewhat green- 

 ish color, under the lens covered with close, oblique, cuticular 

 longitudinal riblets. The conic spire has an obtuse apex. 

 The 4 inflated whorls are separated by a deep suture. The 

 last whorl forms two-fifths of the total length, descends very 

 slightly in front, and is inconspicuously angular at its periph- 

 ery. The oblique aperture is long-rounded, with a straight, 

 thin peristome, reflected and dilated at the insertion of the 

 columellar margin; on account of the very strong expansion 

 of the columellar reflection an umbilical crevice may be 

 spoken of. The terminations of the lip converge. On the 

 base of the last whorl a very delicate spiral striation may be 

 observed in some examples, under a very strong lens. Alt.
