Original description : " Shell elongately subulate, apex some- 

 what papillary, whorls fourteen to fifteen in number, flat, 

 obliquely very closely and somewhat rudely sculptured with 

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

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

 The rib-like stria3 of this fine species, contributed by Mr. Benson, 

 have an oblique plicate growth." (Reeve.} 



Bab. India : Naga Hills (Roberts) ; Toruputu, Naga Hills and 

 Dana Hills (Godwin- Austen) : N. Cachar Hills (Pilsbry). 



Reeve, 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 it in the Naga 

 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.
