Orifjlnal descriptioH: — "Shell elongately subulate, apex some- 

 wbat papillary, whorls fourtiieu to fifteen in number. Hat, 

 obliquely very closely and somewhat rudely sculptured with 

 rib-like "striae, sutures impressed. Columella arched, abruptly 

 truncated ; whitish, covered with a tliiu olive-brown epidermis. 

 The rib-like striie of this fine species, contributed by Mr. Benson,

Ilah. India: Naga Hills (/i'o/>e;-?s) ; Toruputu, Xaga Hills and 

 Dafla Hills {Godwin- Austen) ; X. Cachar Hills {Filshrij). 



Eeeve, when describing and figuring the species, attributed it 

 to the Cassia [Khasi] Hills, but Lt.-Col. Godwin-Austen states 

 (P. Z. S. 1872, p. 517, footnote) that he obtained itin the Xaga 

 Hills, never in the Khasi. Later he again referred to it (J. A . S. B. 

 xlix, 1875, p. 3) saying that he suspected Griffith's specimens were 

 obtained in the Naga Hills and sent to Benson, who imagined 

 they were from the Khasi Hills.
