NESOPUP.-E OP INDIA AND CEYLON. 345 



V. SPECIES OP INDIA AND CEYLON. 



Three of these species, filosa, brevicostis and salemensis, 

 belong near N. moreleti and its East Indian allies. N. barrack- 

 porensis is not specifically separable from Philippine speci- 

 mens referred to N. malayana, described from Borneo, and is 

 also related to species of the Comoros and Africa. The teeth 

 of N. cinghalensis have not been described or figured in suffi- 

 cient detail for a decision, but it is probably near barrack- 

 porensis. The Nesopupa fauna of the Oriental Region is thus 

 quite homogeneous. 



Specimens of filosa and barrackporensis have been exam- 

 ined, the accounts of the others being compiled. 



Angular lamella curved, rather high ; shell ovate. 



Length 2 mm., irregularly striate. N. filosa, no. 42. 



Length 1.5 to 1.75 mm. 



N. brevicostis, no. 43 ; N. salemensis, no. 44. 

 Angular lamella low, straight ; shell cylindric ; length 2 mm. 



Seven teeth. N. cinghalensis, no. 45. 



Five teeth. N. barraekporensis, no. 46.

The shell is ovate, imperf orate but shortly rimate, dull, 

 cinnamon-buff, thin, having rather strong but unequal striae 

 widely but unequally spaced, the intervals vermiculate-gra- 

 nose. Outlines of spire convex, the summit obtuse ; penult 

 whorl large, strongly convex ; last whorl having a slight 

 impression behind the outer lip, over the upper palatal fold. 

 Aperture with 5 teeth: angular lamella rather low in front, 

 higher within, curved, joining the outer lip. Parietal lamella 

 high, slightly sinuous, not entering very deeply. There is 

 usually a vestigeal infraparietal tubercule, so low that it is 

 readily overlooked. Columellar lamella rather deeply placed, 

 subhorizontal. Two rather short palatal folds, the upper low, 

 lower much higher. The peristome is narrowly reflected, 

 colored like the shell, slightly thickened, thinner at the sin-
