and scarcely any swelling ; aperture oblique, ovate, tlie upper outer 

 margin protruded forwards, behind the aperture; peristome simple, 

 double, rounded below, augulate near suture, nearly vertical on the 

 columellar side.

This shell I found in the Elanford colleciion, it came from me; 

 two had been sent, one was missing ; it was labelled theohnh/i, var. 

 In form it is curiously like A. commutatns an allied subspecies, 

 as well as in the type of sculpture and the operculum, but the 

 aperture is quite distinct.

Localitij. Toru[)utii Peak, Dafla Hills, two specimens {Godwin- 

 Austen). 



Shell globosely pyramidal, openly umbilicated, remains of a dark 

 epidermis ; sculpture on u])per whorls, fine, irregular, rather close, 

 raised strise, becoming finely costulate for the length of the sutural 

 tube : colour whitish, probably pale brown when younger ; spire 

 fairly high, apex small ; suture impressed, the tube moderately 

 long; whorls 4, well rounded, the last slightly constricted then 

 swelling into a straight ridge halfway between the costulate portion 

 and the aperture ; aperture oval, oblique ; peristome simple, 

 straight, yet curving slightly on the columellar side, rather flat 

 below, curving up on the outer margin ; operculum black, smooth. 



Size : maj. diam. 5"25 ; alt. axis 30 mm. 



In form quite distinct from A. tIteobahU of the Khasi Hills,

Orir/mnl description.— " Shell globosely turbinate, narrowly um-

 upper whorls, close and fine ribbing on swollen portion of the last. 

 Spire conoid, suture fairly impressed. Wht)rls 4.). closely wound, 

 the last swollen, then sharply constricted, and again enlarged and 

 descending, the expanded portion being marked with deep fold-like 

 furrows. Sutural tube moderate, aperture oblique. Peristome 

 very thick, distinctly treble in full-grown shells, outer layer termi- 

 nating just behind the aperture, the inner continuous, the two outer 

 much reflected near the umbilicus. Operculum smooth in front.
