286 PUPTLLIDJE. 



two species identical * may possibly have had specimens of 

 barrackporensit [indica, Pir., uon Benson] labelled brevicostis 

 before him, and was thus misled. The two are perfectly distinct 

 as will be seen on comparison of the figures. 



254. Pupilla cinghalensis, sp. n. 



Shell narrowly perforate, almost riniate, cylindrical-ovate, rather 

 solid, very minutely striatulate, the earlier whorls corneous, the 

 later ones rufous. Spire convex, apex obtuse, suture impressed. 

 "Whorls 5, slightly convex, the last flattened and scrobiculate 

 behind the peristome, shortly ascending, slightly compressed and 

 subangulated around the extremely narrow perforation of the 

 umbilicus. Aperture oblique, broadly obovate, furnished with 

 seven denticles ; 2 compressed, elongate, on the parietal wall, 

 2 very minute and deeply seated, on the columella, 3 also very

minute and deeply seated, on the palatal wall. Peristome rufous, 

 slightly thickened and reflexed ; outer margin slightly inflexed, 

 basal margin rounded, columellar margin obliquely ascending and 

 slightly dilated above. 



Long. 2, diarn. 1 mm. 



Hob. Ceylon. Type in the British Museum. 



This new species is based on a specimen from Ceylon, without 

 precise indication of habitat, acquired by me some years ago at a 

 sale. It differs from P. barrackporensis, its nearest ally, in 

 having se\ 7 en instead of four denticles in the aperture, and in 

 having the peristome fulvous instead of white.
