According to Theobald the present species cannot be separated 

 from E. canddaris, Pfeiffer, as he considered the main distinction 

 to be in the texture of the shell. A careful examination of a con- 

 siderable number of the two species, however, has convinced me 

 that they can be readily distinguished, not by the texture, but by 

 the shape of the shell, domina having a much greater diameter in 

 proportion to its length, while it is also much more marked with 

 dark transverse streaks, candelaris being generally of a chalky white, 

 only the upper whorls occasionally being variegated in this manner. 



The Theobald collection contains dextral forms of E. domina, 

 from Tandiaui, Hasara, a station at an elevation of 5000 feet, and 

 sinistral specimens from Mari [Murree]. The former range from 

 29-5 x 9-5 to 26-5 x 9-25 mm., and the latter measure 30-5 x 10 mm. 

 There are besides in the British Museum two shells collected by 

 Major Spratt at Lundi Kotal.

Shell moderately umbilicated, fusiform-pyramidal, white, shining, 

 distantly and irregularly striated, the striae crossed by obsolete 

 spirals. Whorls 9, the protoconch consisting of 2 whorls 

 smooth and polished, rather convex, the remainder more flattened, 

 increasing rather rapidly, the last slightly ascending, equalling J 

 of the spire. Spire subconoid, suture shallow. Aperture scarcely 

 oblique, obovate ; margins connivent, united by a thin callus on 

 the parietal wall ; peristome slightly thickened, expanded, and 

 reflexed, with acute edges ; upper, outer, and basal margins regu- 

 larly curved ; columellar margin vertical, triangularly dilated ; 

 umbilicus narrow, rimate, subangulated around the base of the 

 shell.
