ENA. 231 



Hob. India : Alinorah, Kumaon, N.W. Prov. (Boys). 



This species is allied to E. nilagirica, Pfeiffer, but is considerably 

 smaller in size with a more conoid spire and a smaller aperture. 

 The Theobald collection comprises specimens measuring 14 x 5-5 

 mm. and 12*5 x 6-25 mm., the former being marked with transverse 

 hydrophanous streaks.

 Hills (Fairbank}. 



Nevill, in Hand List, i, p. 135, enumerates, but does not 

 describe, two varieties elongata and pulneyana. 



The shell figured as nilagiricus in Conch. Ind. does not pertain 

 to Pfeiffer's species and has been separated by Kobelt as 

 B. Tiarileyanus. 



The length indicated by Pfeiffer in the original description 

 28^ mm. is probably a misprint for 18 J, since of three specimens 

 from the Cuming collection, mounted on a tablet which bears a 

 label in Pfeiffer's writing, two measure 19*5 x 8 mm. and the 

 third is 17'5 mm. long with a diameter of 6 mm. They are 

 marked with some transverse, whitish, diaphanous streaks and 

 bear very close, incised, wavy spirals, two features not mentioned 

 in the diagnosis. In the Beddome collection are some shells 

 ranging from 16-25 x 6'25 to 15 x 6 mm. 



E. nilagirica differs from E. ceratina in having a more slender 

 spire, and a greater number of whorls ; the aperture is less dilated, 

 and the upper and outer margins of the peristome are less curved.
