conica, apice obtuso, sutura subprofunda ; anfractibus 5, convexis, 

 ultimo antice ascendente circa umbilicum excavatum coinpressius- 

 culo; apertura quaclrato-ovata, niarginibus, expansis subreflexis con- 

 coloribus callo parietali expanse superne junctis, 4-dentata, dente 

 parietal! 1 entrante majore, palatalibus 2 miuutis remotiusculis,

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



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

 tbe Nerbudda Eiver (Theobald] ; Mul Eiver, Western India 

 (Theobald). 



This appears to be a rare form. I have not seen specimens. 

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

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

 which are situate on the columella.

Original description : " Testa rimata, ovato-obliqua, subcylin- 

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

 apertura ovato-rotundata, quinqueplicata ; peristornate expaiisi- 

 usculo, marginibus callo tenui junctis ; plica unica irregulari, 

 sinuata, parietalis, columellaribus duobus, palatalibus duobus 

 profundis. 



" Long. 1| mill., lat. vix 1 mill." (Benson.) 



Hob. India : Simla (Hutton) Siud (Blanford) ; Kashmir and 

 Deccan (Stoliczka) ; Ahmeduuggar (Theobald)-, Wadale (Fair- 

 lank) ; Kashmir : Panjal Range (Theobald). 



Some shells from Simla in the Theobald collection are referred 

 here with some doubt. The 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 J856, 

 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.
