about Kathai fort on the right bank, where it is abundant, 

 although he saw only dead shells. He further observes that its 

 range must be very limited, not having noticed it to the eastward, 

 or anywhere in the cis-Ravi country. 



E. pretiosa has a close affinity with such species as E. eremita 

 and E. ccelebs, but is more conoid in the spire than the former 

 and considerably smaller than the latter, being also differently 

 marked. From E. rufistrigata, another ally, it may be separated 

 by the broader base and the more convex spire. Three specimens 

 in the Theobald collection are from the type locality. They 

 agree with Reeve's figure, except in size, measuring 16x7'5 mm. 

 They are rather thin in texture, and are densely covered with 

 excessively minute, wavy spirals, a feature not mentioned in the 

 original description. The upper margin of the peristome strongly 

 arches forward. In the British Museum are also five specimens 

 collected by Major Spratt at Lundi Kotal. These range in size 

 between 21 x 8, 18-5 x 7, and 16 x 7 mm.

Original description : " Narrowly and superficially rimate, 

 subcylindrically conical, of stout, smooth, and polished substance ; 

 striated, strisB'less oblique than in the preceding \_stoliczJcanus\ y 

 fewer and more regular, not crowded together in the same way, 

 here and there one more developed than the others, with inter- 

 mediate ones more or less obsolete ; light horny-brown, variegated 

 with opaque white markings, as in B. pretiosus ; these markings 

 are fewer, of a more zigzag, broader, and more irregular nature 

 than those of the preceding ; spire produced, apex scarcely 

 obtuse ; whorls 7, the three apical ones unusually short compared 

 with the others, last whorl compressed ; aperture very small, 

 almost as broad as high, peristome pure white, outer margin con- 

 siderably thickened ; columella very broadly reflected, straighter 

 than in the preceding, slightly subangulate, instead of rounded, 

 at base. 



"Long. 10, diam. 4J (last whorl to base of aperture, 5|) ; 

 apert. alt. 3|, lat. 3 mm."

" There is no Indian species with which I can compare this 

 species. As to shape, the nearest I know of are some small 

 dwarf forms of Cylindrus insularis ; the species is, however, next 

 allied to B. pretiosus and B. ruftstngatus." (Nevill.} 



Theobald collected what he took to be a variety of this shell on 

 the hills north-west of the Pakli Valley from 4000 to 5000 feet,
