44 Records of the Indian Museum. [VoL. XVIII, 
mented with very fine longitudinal tidges and striae but without 
transverse striae. The shape is regularly, narrowly ovate, with 
the apex sharply pointed. The suture is not impressed and slightly 
oblique. The whorls, of which there are 44, increase gradually in 
size. The spire is prominent, but short, slightly oblique as a 
whole. It occupies a little less than } of the total length in dorsal 
view and is only a little longer in ventral view. The body-whorl 
is ovate and not at all swollen, almost bilaterally symmetrical. In 
dorsal view the internal profile forms for the greater part of its 
length from the base of the spire a regular arc a little less than a 
semi-circle but is distinctly constricted in front of the internal 
anterior angle, which is broadly rounded and slightly produced. 
The mouth of the shell is long and narrowly pear-shaped, pointed 
and slightly introverted posteriorly. It runs backwards for about 
the length of the body-whorl. The outer lip is sharp, not at all 
thickened internally, broadly and regularly arched but not ex- 
panded. The columella is straight and slightly folded. Its callus, 
which is continuous with the outer lip posteriorly, is moderately 
developed. The anterior margin of the mouth is rounded and 
projects slightly. The columellar callus completely covers the 
very narrowly rimate or altogether closed umbilicus.

Shells from the two localities only differ in size. Our speci- 
mens are those examined by Nevill. 
Radula. We have extracted the radula from one of Blanford’s 
specimens in which remains of the animal persisted. It is of the 
same type as that of L. bactriana but differs in several particulars. 
‘The base of the central tooth is distinctly bilobed. The three 
cusps of the inner lateral teeth are long and sharp, but those of 
the intermediate bicuspid teeth are short and blunt, the inner 
cusp being broadly truncate. The marginal teeth are somewhat 
remarkable, having the outer margin coarsely denticulate, one of 
the denticulations being often of a lobular nature. The dental 
formula is approximately 12.7.1.7.12.

Localities. ‘The only specimens we have seen are those col- 
lected by Dr. Blanford in Persian Baluchistan and at Magas in 
Southern Persia. There is a good series from each locality.
