Show 380 MR. E. A. SMITH ON THE [Apr. 18, Greatest width 26 millim., height 17. 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 crisscross stria in addition to the lines of growth. It is also more acutely carinate, has a less convex spire, and the body-whorl is considerably smaller and less inflated below the periphery. In H. cleamesi the sculpture consists of concentric stria crossing the lines of increase and rendering them beautifully granular on the upper surface. HELIX (KALIELLA) BARRAKPORENSIS, Pfeiffer. Helix (Kaliella) barrakporensis, Pfeiffer, Conch. Cab. pl. 147, f. 20-22; Reeve, Con. Ic. f. 816; Hanley, Conch. Indica, pl. 87. f. 7. Hab. About 30 miles east of Antananarivo (Johnson). On comparing the three specimens of this species from tbe 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 conclude that this species (like Achatina fulica) has been introduced into India. HELIX (HELICOPHANTA) BICINGULATA, sp. nov. (Plate XXI. figs. 13, 14.) Helix cornu-giganteum, Angas (non Chemnitz), Proc. Zool. Soc. 1877, p. 527. H. guestieriana, Angas (non Crosse), op. cit. 1878, p. 312. 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 periphery, 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 commencement, 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. Aperture obliquely elongate, bluish lilac within. Lip wbitish, expanded, reflexed. Columella thickened, arched forward a trifle just beneath the umbilicus, very granular, expanded and reflexed over tbe perforation, sometimes not quite closing it |
