“The Sikkim and Landour H. vimicola, Bens., is the nearest form 
to H, injussa with which we are acquainted. The Nilgiri shell has 
a higher spire, and is considerably smaller in size. From the com- 
paratively large H. infula, Bens., H. injussa may be easily distin- 
guished by the absence of the peculiar sculpture of that species, as 
well as by its fewer whorls and smaller size.” 
The specimen figured is in Mr. Blanford’s collection and from 
original locality ; there are two other specimens also from the Nilgiri 
Hills, No. 58 of his MS. list. 
On the last whorl rather strong, spiral, parallel, somewhat wavy 
ridges are crossed by irregular lines of growth; on the apical whorls 
the transverse ridges are more regular and close together, giving an 
almost decussate appearance. ‘The aperture is very oblique, and the 
peristome on outer margin sinuate above, so that the columellar 
margin is distinctly seen from the side. This specimen measures 
in major diam. 4:2, alt, axis 3-2 mm.

«« This species bears a general resemblance to H. tricarinata above 
described, but is readily distinguishable by its higher spire, the 
absence of the characteristic triple carination, and the flatness of 
its basal surface. The two specimens received from Mr. Foote are 
both much weathered, and have lost their colour and much of the
