MOLLUSCA OF IlfDIA. 399 



" Major diara. 0-14, minor diam. 0-10, alt. 0-08 inch. 



" Hab. Obtained by me on the hill-ranges from near Tellizo Peak 

 to the eastward and on Miuigching Hill in Manipur, Abundant. 

 • " This species is very close to A. crispatus, G.-A., from the Khasi 

 and Jaintia Hills, J. A. 8. B. xl. pi. iv. fig. 1, but is a much more 

 closely wound shell — a character which, when a large series of the 

 two were placed side b)' side, was found to be constant ; and this, 

 with the absence of the ridge on the constriction, marks it as 

 distinct. A. sculptilis, Bs., originally described from Burma — of this 

 I collected identical specimens in Munipur — is another form near 

 A. scuJpturus, but has no crenulation of the peristome and is plain 

 and ridgeless on the constriction ; the three forms pass into one 

 another." 



The above reference to A. scuJptiKs was unfortunately made 

 under some misconception of the form of the species, the Munipur 

 specimens referred to are described as A. tanghali. 



Typical A. sculpi'dis seen since in Blanford's collection from 

 Thyatmyo, Pegu, has very fine serration within the aperture (see 

 PI. CLV. fig. 8).

Original description : — " Shell globosely turbinate, thick, pale 

 horny, finely and closely ribbed from the swell of the first whorl as 

 far back as the end of the sutural tube, thence to the apex distantly 

 and finely costulated, narrowly umbilicated ; spire conoid, apex 

 blunt ; suture well impressed ; whorls 4|, rounded, the last 

 swollen, then sharply constricted close to the origin of the sutural 

 tube, again swelling and expanding to the mouth ; constriction 

 smooth, with a few distant lines of costulation. The sutural tube 

 peculiarly long. Aperture oblique, circular ; peristome double, 

 outer lip small, the inner much produced and expanded into two 

 broad, shallow channels on the inside of the outer margin, separated 

 by a V-shaped thickening of the same (see fig. 3 b). Operculum 

 black, concave, of the usual multispiral form.
