Shell umbilicated, depressedly ovate, closely and arcuately ornamented 

 above with subcostulate striation, polished, translucent, pale yellowish 

 white. Spire low, conical, but little exserted, apex obtuse, suture but little 

 impressed. Whorls h\, the upper slightly convex, the penultimate rounded 

 behind and projecting considerably beyond the lower whorl when viewed 

 from below ; last whorl very eccentric, somewhat flattened beneath, smooth, 

 except within the umbilicus, where there are fine, irregularly flexuous 

 filiform raised lines on the surface, compressed around the umbilicus and 

 anguhite near the aperture, where there are deep indentations correspond- 

 ing to the teeth inside. Aperture oblique, truncately oval, furnished with 

 a strong re-entering parietal plait, curved within and subbifid in front, and 

 with four teeth — one columellar, one basal, and two (of wliich the upper 

 is small) inside the right margin. Peristome thickened, subcontinuous, 

 white, expanded, the margins joined by a thick callus projecting from the 

 body-whorl and bearing the parietal lamella, Major diameter 0'26, minor 

 O IG, height 0-12 inch. 



This shell resembles S. compressus in form, but it wants the angula- 

 tion of the penultimate whorl. The peristome is much thickened, as in 

 8. personatus. 



The forms of LEnnea and Streptaxis described in this paper are the 

 principal that have been collected in the Southern Indian mouutains by 

 Colonel Beddome, from whom I have received specimens from various 

 localities from time to time. All of the species of Streptaxis are some- 

 what variable,_and, with a large collection from South India, it would
