Hab. Ankafana, 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 strie 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 strie crossing the 
lines of increase and rendering them beautifully granular on the 
upper surface.

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. Hutton, 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, darker 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. Volutions 4, 
very rapidly increasing, convex, separated by a deepish suture ; two 
upper 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 Jines of growth, 
and oblique, close, short indentations like the upper surface, rounded 
at the periphery. Aperture obliquely elongate, bluish lilac within. 
Lip whitish, 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,
