PUPILLA, ASIA. 203 



tracted behind the lip ; very little and slowly ascending in 

 front. The aperture is small, rounded, subvertical, obstructed 

 by four teeth : a nodular angular, continuous with a strong 

 callous ridge running to the columella, some distance within 

 the parietal margin; a stout, curved, entering parietal lamella, 

 deeply placed ; a very strong, blunt, axially lengthened colu- 

 mellar lamella, situated rather high, and a stout lower-palatal 

 fold, deeply placed. The peristome is white, reflected, 

 strongly thickened within except at the upper curve of the 

 outer lip, where it becomes thin ; it is continuous in a raised 

 ledge across the parietal wall. Length 2.85, diam. above aper- 

 ture 1.45, length of aperture 9.5 mm. ; 6 whorls. 



Upper Burma: Ava? (coll. Indian Museum, Calcutta, from 

 W. Theobald). 



Pupa (Vertigo] sp., G. NEVILL, Handlist of Mollusca in the 

 Indian Museum, i, 1878, p. 197, no. 97. 



Nevill doubted the locality Ava. It is probably not a shell 

 of the Oriental fauna; more likely Theobald got it in Nepal, 

 as it belongs to the central Asian group comprising P. inter- 

 rupta, P. heudcana, P. diccki etc., found from northern China 

 to Persia and southern Russia. 



The type is decolored, whitish, perhaps a river-drift shell. 

 Besides the striation, which is stronger than in any of its 

 known allies, it is distinguished by the continuous peristome, 

 by the transverse parietal callus, terminating in a rounder! 

 angular tubercle, widely separated from the strong parietal 

 lamella, and by the single strong palatal fold, externally sig- 

 nalized by deep furrow. 



Named for Dr. N. Annandale, who is doing admirable work 

 on the freshwater mollusks of India.

"Shell perforate, ovate-cylindric, rather solid, somewhat 

 obliquely striatulate, rufous-chestnut, a little shining. Spire 

 ovate-cylindric, the apex obtuse, suture impressed, submar- 

 ginate. Whorls 7 to I 1 /?, convex, the last ascending in front. 

 Aperture semiovate, suboblique, toothless; peristome a little 

 expanded, whitish, the right margin outwardly thickened pos- 

 teriorly. Length 2.5, diam. 1 mm." (Benson).
