P. ligiiicola* a form very closely resembling P. evezardi, but rather 

 shorter and less ovate. It is by no means improbable that intermediate 

 varieties may be found ; indeed, so much do I doubt whether the two are 

 really worthy of distinction that I should not liave described the present 

 sj^eeies if the name had not already crept into print. 



Mr. Nevill, in his Hand-list I. c, has referred the Helix orcula of 

 Benson to the same section of Pupa as P lignicola ; and in this he is, I 

 think, unquestionably right.

Shell conically ovate, rather thin, but little polished, distinctly and 

 flexuously striated, greenish horny in colour. Spire step-like, apex rather 

 pointed, suture much impressed. Whorls scarcely 3, very convex, the last 

 about f of the length. Aperture oval, oblique ; peristome thin, the right 

 margin moderately curved forwards ; the columella arcuate, receding, and 

 covered with a thin callus. Length 076, diameter O-i, height (when laid 

 mouth downwards) 0'24 inch ; length of aperture 52, breadth 36 inch. 

 The largest shell I possess measures 20 mm. in length (0-8 inch). A 

 rufous variety occurs at Torna Hill, near Sinhgarh, west of Poena. 



This is a rock-inhabiting species, f found on cliffs and large blocks 

 of basalt at Mahabaleshwar and Torna, and is allied to 8. girnarica, a 

 larger and thicker form, rather differently shaped, found by Mr. Theobald 



* J. A. S. B., 1871, vol. xl. pt. 2, p. 171. 



t It is rather difficult to understand why Succinea should be placed amongst fresh- 

 water shells in the ' Conchologia Indica.' Most of the Indian forms are found either 

 on trees (often on palms) or on rocks, and generally at a distance from water, lithotis 

 and Camptonyx arc also, I think, incorrectly classed us freshwater shells, loth being 

 found on basaltic cliffs.
