 constricted by indentations behind 



the peristome ; aperture semioval,

Shell rimate, perforate, depressedly ovate, solid, with flexuous 

 costulate striation above, smooth beneath ; spire depressedly conoid ; 

 whorls 6^, flattish, penultimate obtusely keeled, projecting by fully 

 half its breadth beneath beyond the last whorl, which is slightly 

 convex below, compressed and subangulate near the aperture, 

 rugosely striated inside the umbilicus ; indented outside behind 

 the peristome ; aperture semioval, with 1 or 2 parietal lamellse, 

 the outer small or wanting, and 3 palatal teeth ; peristome

30. Streptaxis compressus, Blf. J. A. S. B, xlix, pt. 2, 1880, p. 201, 



pi. 2, fig. 13. 



Shell openly subuinbilicated, very depressed, striate, translucent, 

 dull yellowish ; spire almost flat ; whorls 4|, flattened above, but 

 with the suture impressed, the penultimate whorl bluntly carinate, 

 projecting by nearly its whole breadth when seen from beneath, 

 last whorl flattened below except near the peristome, where it is 

 compressed into a ridge, indented behind the aperture, which is 

 nearly semioval, but with the margins converging distally ; peri- 

 stome expanded, slightly sinuate at angle ; parietal lamella bifid 

 or double ; palatal teeth 4 or 5, two columellar teeth being close 

 together and generally united. 



Length 6|, breadth 3|, height 3 mm. 



Hob. Sivagiri Hills, Tinnevelly ; and hills near Cumbum in 

 same district. The variety from the latter locality is filiformly 

 striated above and within the umbilicus, and the parietal lamella 

 is double.
