 p. ]] ; Pfr. (Helix) Mun. Hc4. v, 1868, p. 244; H. 8,- T. (Helix) 

 a I. 1876, pi. 25, fig. 2, pi. 52, fig. 4. 



Hemiplecta tinostoma, BIf. J. A. S. B. xlix, 1880, p. 187, pi. 3, fig. 1. 



Hemiplecta enisa, Blf. t. c. p. 188, pi. 3, fig. 2. 



Shell narrowly umbilic.atetl, depressed, tliick, covered with a 

 yellowish-brown epidermis, beneath the epidermis pale purplish, 

 with a narrow whitish band above the ])eriphery, darker and 

 browner below the band : sculpture subgranular, formed by striae of 

 growth decussated by close, fine, slightly flexuous impressed lines ; 

 spire convex, low, suture slightly impressed, more so near the 

 mouth ; whorls 4|, the upper nearly flat, the last more convex 

 above, moderately tumid below, rounded at the periphery, scarcely 

 or not descending anteriorly ; aperture oblique, oblong-ovately 

 lunate ; peristome thickened in old shells, especially at the basal 

 margin, columellar margin oblique, reflected, partly covering the 

 umbilicus and terminating abruptly in a small point. 



Major diam. 45 (a large shell 53), min. 38, axis 24 mm. ; mouth 

 23 broad, 17 high. 



Hah. Hills near Kotiyam, Travancore (Dai/), Pulueys and 

 Anairaalais, 7000' (Beddome). Not known north of the Palghat 

 Gap. 



A. tinostoma is much depressed, with an elongate mouth, having 

 the upper and basal margins parallel and the last whorl broad 

 near the aperture and subangulate at the periphery. 



Major diam. 49, min. 40, axis 21 mm. ; aperture 26 broad and 

 18 high. 



A single specimen was obtained on the Tinnevelly Ghats, east 

 of Papanassam, at 5000 feet elevation, by Col. Beddome. 



A. enisa was found, also by Col. Beddome, at an elevation of 

 6000 feet on the top of Aghastyamalai, a hill near Cape Comorin, 

 between Tinnevelly and Ti avancore. It is smaller and less thick 

 than typical A. hasilessa, and the aperture is less elongate. 



Major diaui. 46, min. 38, axis 23 mm.; aperture 24 broad, 19 

 high. 



These two forms look very different at first, but they are, I 

 think, varieties of A. hasilessa, which, if they are included, inhabits 

 the Travancore hills generally ; A. enisa, as noticed under A. clienui, 

 passes into that species. 



Ariophanta gardeneri, i/r.* (Helix) Mart. ^- Chemn. Conch.-Cuh. 

 ed. 2, 1846, Helix, uo. 703, pi. 112. figs. 12, 13; id. (Helix) 

 Mon. Hel. i, 1847, p. 47 ; id. t. e. vii, 1876, p. 87 ; K. S^ T. (Helix) 

 C. I. 1876, pi. 84, fig. 7. 



Shell subobtectly perforate, turbinate, solid, yellowish brown to 

 dull chestnut, with a narrow pale band round the periphery, sub- 

 costulately striated, with a few decussating spiral lines at con- 

 siderable regular intervals, these lines, formed of raised points on 

 the striae, are continued to the epidermis but are often wanting ;
