 well truncate at the end. 



35. S. PAUCISPIRA Martens. PL 14, fig. 51. 



Shell elongate, almost turrited, without umbilical fissure, 

 finely striate, the growth-striae just below the suture some- 

 what stronger and somewhat curving backward; glossy, 

 pale yellowish, translucent. Whorls 8, <the first globose, form- 

 ing an obtuse apex, the second hardly wider than 'the first; 

 from the third whorl on it increases regularly in diameter, 

 with a very slightly sunken suture, the last whorl rounded, 

 gradually tapering. Aperture rather oblique, about a third 

 the total length, acutely ovate; outer margin thin, moder- 

 ately arcuate; basal margin narrowly rounded; columellar 

 margin strongly arcuate, obliquely but very decidedly trun- 

 cate. Length 25, diam. 7.5, aperture 8x4 mm. A slender 

 example measures, length 23, diam. 6.5, aperture 7 x nearly 

 4 mm. (Marts.).

This species has on first sight the appearance of a Hapalus 

 (Curvella), from its thin, very glossy shell, the comparatively 

 large last whorl and the retraction of the striaB below the 

 suture ; but the structure of the eolrunellar margin is wholly 

 that of Subulina. Also, the further course of the growth- 

 strise is not arched forward, and the obtuse apex agrees better 

 with Subulina. (Marts.)
