Original description : — '■'■ ^heW turretecl, very elongate, pale, 

 silky with a green tinge, older specimens of a pale straw- colour, 

 covered with a thin epidermis, beautifully striate under lens. 

 Whorls 11-12, moderately rounded and very gradually diminishing 

 in size to the apex, Mliieh is blunt ; suture impressed ; aperture 

 angular above, outer lip thin. 



"Alt. 0-55" [ = 14 mm.], major diam. OlO" [ = 2-5 mm.]. 

 Largest specimen 0-90" [ = 23 mm.]." {Godwin- Austen.) 



Hah. India: Dafla Hills, Assam ((?ocZ«'in-^«,s<eu). 



"■ Tliis very delicate elongate shell was common on Toruputu 

 Peak, but far finer specimens, equal in size to the figure, were 

 obtained on the banks of the Pichola Nulla out in the plains. 

 I am not satisfied with this fi.gure ; the whorls being i-ather too 

 fiat and the apex too sharp." (Godtvin- Austen.) 



Prof. Pilsbry (Man. Conch, ser. 2, xviii, 1906, p. 157) states, 

 '• Nevill in his Hand List Ind. Mus. i, p. 165, lists Stenogyra 

 (Opeas) nevilli, G. Ad., from the Dafla Hills. It is undescribed 

 and unknown to me." The " Gr. Ad." in Nevill's Hand List is 

 evidently a printer's error for '* G.-A." and this probably put 

 Pilsbry off the track.
