322. Opeas nevilli, Godwin- Austen. 



Opeas nevilli, Godwin- Austen, J. A. S. B. xlv, 1876, p. 315, pi. 8, 



fig. 12. 

 Stenogyra (Opeas) nevilli, "G. Ad.", Nevill, Hand List, i, 1878, 



p 165. 



Original description : " Shell turreted, 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, which is blunt ; suture impressed ; aperture 

 angular above, outer lip thin. 



"Alt. 0-55" [ = 14 mm.], major diam. 0-10" [=2-5 mm.]. 

 Largest specimen 0-90" [ = 23 mm.]." (Godwin- Austen.} 



Hob. India: Dafla Hills, Assam (Godwin- Austen}. 



" This 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 ]S r ulla out in the plains. 

 I am not satisfied with this figure ; the whorls being rather too 

 flat and the apex too sharp." (Godwin-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 NevilPs Hand List is 

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

 Pilsbry off the track.
