Original descripiion : — "Testa sinistrorsa, profunde rimata, 

 cylindracea, ruditer suboblique striatula vel striate costata, griseo- 

 alba, in aufractibus superis corueo obsolete strigata, summo rufo- 

 cornea. Spira supra conico-attenuata, apice acutiusculo. An- 

 fractus 9 vix eonvexiusculi, leniter ac regulariter crescentes, sutura 

 inipressa, inter inferos submargiaata discreti, ultimus basi rotund- 

 atus, postice altitudinis \ vix siiperans, antice vix ascendens. 

 Apertura subsemicircularis, albida ; peristoma album, undique 

 expansum, acutuin, tenue, tenuisaime labiatum, mai'ginibus baud 

 junctis, columellari parum dilatato, patente, cum pariete apertu-

Hah. ? Northern India. 



The specimens on which the species is based were sent to 

 Dr. Kobelt by the late Miss Linter as B. arcuatus, var., but the 

 form is evidently nearer to E. vibex, from which it differs by its 

 more slender, more cylindrical shape and the more distinct sculp- 

 ture ; the markings are also more distinct and the aperture is 

 proportionately larger and wider. The Theobald collection in the 

 British Museum contains three specimens from Mahasu, \^hich I 

 refer to E. linterce ; they range in size from 15*5 x 6'5 to 20 X 

 8 ram.

I have not seen specimens ; the type, like so many of Benson's, 

 has apparently gone astray. Judging from the figures the species
