Pfeiffer supplies the following measurements from specimens 

 sent to him by Benson (Mon. Helic. A'iv. iii, p. 499) ; " Long. 22, 

 diam. 7 mill. Ap. oblique Ik mill, longa, medio 4 lata."

" I fonnd the smaller variety very abundant on the top of 

 Myhendra Hill (Ganjam). The larger variety, found near 

 Calcutta and in Central India, and well tigered by llauley, is a 

 rare shell. It has a shorter and blunter apex and fewer whorls 

 than vadaUca, but specimens of that species sometimes do duty 

 for it in collections." (Beddomc.) 



The " smaller variety,'' referred to by Beddome, is quite a dis- 

 tinct form on which I have based the next species. 



405. Grlessula ganjamensis, sp. n. 



Shell cylindrico-conoid, opaque, rather solid, a little shining, 

 finelv and closely striated under a greenish or yellowish deciduous 

 cuticle, the striae slightly tlexiious near the upper suture. Spire 

 convex; suture impressed, crenulate ; apex obtuse. Whorls 7, 

 slightly convex and somewhat gibbous at the upper suture, the 

 last whorl equalling in width about ^ of the entire length of 

 the shell. Aperture nearly vertical, sub-ovate ; peristome a little 

 thickened, parietal callus scarcely perceptible ; outer margin 

 slightly curved, basal margin deeply curved ; columella deeply 

 arcuate, obliquely truncate. 



Length 16-25, diam. 7 mm. ; apert. : height 6, width 35 mm.

This is the form referred to by Beddome as " the smallei" varietv 

 [of 6r. amentum'] \evy abundant on the top of Myhendra Hill.'' 

 It is, however, quite distinct from G. amentum., being not only 

 considerably smaller but more solid, with a more convex spire, a 

 less obtuse apex, a more tumid and relatively higher last whorl, 

 and a narrower aperture. The cuticle appears to be rather 

 deciduous and many specimens have the apex corroded. One 

 specimen with 8 whorls measures 17 mm. in length. Another
