PUPILLA, ASIA. 193 



sometimes the angular dropping out. The embryonic whorls 

 are closely, shallowly pitted, producing an irregular reticula- 

 tion of raised wrinkles, coarser than in the muscorum group. 



16. PUPILLA AEMENIACA (Issel). PL 22, figs. 16, 17. 



Shell deeply rimate, ovate-cylindric, obtuse, very delicately 

 obliquely striate, tawny-corneous, not glossy; whorls 7, a 

 little convex, slowly, regularly increasing, separated by an im- 

 pressed suture ; the last whorl more than one-fourth the total 

 length, slightly ascending to the aperture, compressed around 

 the perforation, carinate. Aperture small, regular, the pari- 

 etal wall having a deeply placed denticle; peristome thick- 

 ened, a little reflected, spreading ; lateral margins subparallel. 

 Length 3, diam. 1.5 mm. (Issel).

No palatal teeth are mentioned. It probably belongs to the 

 P. signata group. 



17. PUPILLA ANTINORII (Palad.). PI. 21, fig. 4. 



Shell broadly and deeply umbilicate, cylindric, slightly sub- 

 ovate, very finely striatulate, little shining, whitish-buff. Spire 

 convex-conic, at the minute apex obtuse. Whorls 7}.<>, little 

 convex, rapidly increasing, especially from the third, separ- 

 ated by a not very deep suture; the last whorl stronglj- 

 ascending at aperture, having two impressed scars behind, 

 somewhat constricted at aperture ; umbilicus surrounded with 

 an indistinct keel; free margin convexly-subsinuous. Aper- 

 ture subovate, wider above ; parietal wall having a rather long 

 tooth-like fold in the middle. Peristome expanded, reflected, 

 the margins separated ; outer margin a little arcuate, having 

 a minute fold somewhat approaching the free end of the pari- 

 etal tooth. One palatal fold, forming a shallow pit outside. 

 Coluraella slightly r.rcuate, having a deeply immersed fold. 

 Outer and inner margins strongly approaching by the in- 

 curving of the lips above. Length 4, diam. 2 mm. (Palad.).
