Pfeiffer supplies the following measurements from specimens 

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

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



Hub. India : Howrah near Calcutta (Reeve, Benson) ; Gran jam 

 (Ball, Beddome) ; Orissa (Beddome). 



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

 Myhendra Hill (Gran jam). The larger variety, found near 

 Calcutta and in Central India, and well figered by Haoley, is a 

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

 than vadalica, but specimens of that species sometimes do duty 

 for it in collections." (Beddome.) 



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

 tinct form on which I have based the next species. 



405. G-lessula ganjamensis, sp. n. 



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

 finely and closely striated under a greenish or yellowish deciduous 

 cuticle, the striae slightly nexuous 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 3'5 mm.

Type in the British Museum. 



This is the form referred to by Beddome as " the smaller variety 

 [of G. amentum'] very 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
