342 EAST INDIAN NESOPUP^E. 



lamella high, rather thin, curving outwardly to join the callus 

 in the posterior termination of the lip. Parietal lamella 

 larger; columellar lamella well developed, subhorizontal ; a 

 small basal fold where the columella curves into the basal 

 margin. The two palatal folds are strong, the upper one 

 high but rather short, the lower more immersed, long, enter- 

 ing deeply. The peristome is well expanded, thickened 

 within, the outer lip rather strongly bent inward in the 

 middle. 



Length 1.55, diam. 0.9 mm.; 4% whorls. 



Length 1.4, diam. 0.9 mm.

This species is distinguished by its fine, regular rib-striae 

 and the absence of accessory teeth. It is also smaller than the 

 related forms. The columellar lamella enters horizontally, its 

 inner end not turned either up or down. The specimen de- 

 scribed and figured is from Quadras. 



N. nannodes is similar to Afripupa in sculpture and prob- 

 ably belongs to that section. 



Section Insulipupa P. & C., n. sect. 



Angular lamella straight, low, joining the outer lip but not 

 penetrating much beyond the outer end of the parietal lamella. 

 Columellar lamella straight or slightly turned up at its inner 

 end. Type N. minutalis (Morel.). 



39. NESOPUPA MALAYANA (Issel.). PL 32, figs. 14, 15, 16. 



Shell very minute, rimate, cylindric-ovate, ornamented with 

 oblique, rough, lamellar riblets under a strong lens ; corneous 

 buff, translucid. Spire tapering, the apex obtuse. Whorls 6, 

 a little convex, parted by an impressed suture, the last about 

 one-third of the total length, slightly ascending at the aper- 

 ture, a little compressed in the middle. Aperture nearly 

 semioval, vertical, 6-toothed: two deep parietal teeth; two 

 columellar, the lower one smaller; two lamelliform palatals. 

 Peristome reflected, the right margin sinuate, columellar ob- 

 lique, lightly arcuate (Issel).
