"Alt. 3, diaoi. 2 mill." (Benson.) 



Hah. India : Teluk Sendur, near Hoshungabad, not far from 

 the Nerbudda River {Theobald) ; Mul River, Western India 

 (Theohald). 



This appears to be a rare form. I have not seen s])ecimens. 

 Benson in his diagnosis states that there are four denticles, one 

 being columellar, but the figure in Conch. lud. shows five, two of 

 which are situate on the columella.

Orhjinal description : — " Testa I'imata, ovato-obliqua, subcj'lin- 

 dracea, hyalina, glabra, apice obtuso ; anfractibus 5, convexis ; 

 apertura ovato-rotundata, quinqueplicata ; peristomate expansi- 

 usculo, marginibus callo tenui junctis ; plica unica irregulari, 

 sinnata, parietalis, columellaribus duobus, palatalibus duobus 

 profundis. 



"Long. Ig mill., lat. vix 1 mill." {Benson.) 



Hah. India: Simla (7/m<<oh) ; ^iwA {Blanford) ; Kashmir and 

 Deccan {Sioliczka) ; Ahmednuggar {Theobald); Wadale {Fair- 

 bank); Kashmir: Panjal Range (I'/teoftrtZcZ). 



Some shells from Simla in the Theobald collection are referred 

 here with some doubt. Tlie parietal plica is bifid and in some 

 specimens there is an additional plica nearer the columella ; 

 others have only one columellar plica. The shells range in 

 length from 1*75 to 2 mm. A number of himalayana from 

 Simla, presented to the British Museum by Hutton in J 856, 

 comprised a specimen of huttoniana. The Beddome collection 

 also contains ten shells of huttoniana collected in Kashmir by 

 Stoliczka; these have likewise a bifid parietal plica, while a single 

 columellar plica occurs in some and two in others.
