Original description: "Testa sinistrorsa, profimde rimata, 

 cylindracea, ruditer suboblique striatula vel striato costata, griseo- 

 alba, in anfractibus superis corneo obsolete strigata, summo rufo- 

 cornea. Spira supra coDico-atteDuata, apice acutiusculo. An- 

 fractus 9 vix convexiusculi, leniter ac regulariter crescentes, sutura 

 impressa, inter iiiferos submarginata discreti, ulthnus basi rotuud- 

 atus, postice altitudinis 1 vix superans, antice vix ascendens. 

 Apertura subsemicircularis, albida ; peristoma album, undique 

 expansum, acututn, tenue, tenuissime labiatum, marginibus baud 

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

 rali angulum distincte formante. 



" Alt. 10. diam. anfr. ult. 7'5, alt. apert. 6-5 mm." (Kobelt.) 



Hal. ? 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, which I 

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

 8 mm.

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

 has apparently gone astray. Judging from the figures the species
