Hab. Ankafaiia, Betsileo province {Cowan). 



There is only one other Madagascar Helix which is likely to be 

 confounded with this species, namely H, balstoni of Angas. The 

 latter has the whole surface minutely sculptured with raised criss- 

 cross strice in addition to the lines of growth. It is also more 

 acutely carinate, has a less convex spire, and the body-whorl is con- 

 siderably smaller and less inflated below the periphery. In H. 

 cleamesi the sculpture consists of concentric strice crossing the 

 lines of increase and rendering them beautifully granular on the 

 upper surface.

Hab. About 30 miles east of Antananarivo [Johnson). 



On comparing the three specimens of this species from the above 

 locality with a series from Simla in India, presented to the British 

 Museum by Capt. T. Button, and also with the types described by 

 Pfeiffer, I am unable to find any distinction, and consequently con- 

 clude that this species (like Achatina fulica) has been introduced 

 into India.

Shell large, ovate, ventricose, imperforate or narrowly rimate ; 

 light olive-brown above, daiker brown towards the lip, with the 

 lower surface beneath the periphery still deeper in tint, encircled 

 by two dark-brown slightly raised narrow bands, one at the peri- 

 phery, the other and more distinct one above it. Spire depressed, 

 convex, only a little raised above the body-whorl. A^olutions 4, 

 very rapidly increasing, convex, separated by a deepish suture ; two 

 npper ones striated by simple arcuate lines of growth ; the third 

 coarsely granular, the lines of growth being but feebly expressed ; 

 the last very large, much descending in front, granular at its com- 

 mencement, the granules gradually disappearing and replaced by 

 close, oblique, short indentations, also exhibiting five or six nearly 

 obsolete concentric ridges above the upper brown zone, and two or 

 three between it and the lower one, the lines of increase being more 

 distinct upon this than the preceding whorl. Lower surface swollen 

 around the umbilical region, marked with arcuate lines of growth, 

 and oblique, close, short indentations like the upper surface, rounded 

 at the periphery. Aj)erture obliquely elongate, bluish lilac within. 

 Lip wliitish, expanded, reflexed. Columella thickened, arched 

 forward a trifle just beneath the umbilicus, very granular, expanded 

 and reflexed over the perforation, sometimes not quite closing it.
