Shell imperforate (sometimes apparently subperforate behind 

 the columellar callus), depressedly globose, thin, opaque, not 

 polished, having an olivaceous rather silky epidermis, and sculp- 

 tured with plicate transverse striae of growth, and with very 

 close, minute, longitudinal (spiral) lines, not always easily detected ; 

 spire subconoidly convex, apex blunt, suture moderately im- 

 pressed ; w^horls 5, convex, somewhat flattened above, the last 

 large, rounded at periphery and swollen beneath, base smoother ; 

 aperture diagonal. Innately oval, having a pearly lustre within; 

 peristome with the epidermis projecting beyond the shell, margins 

 converging, arcuately dilated between upper and outer margin, 

 columellar deeply curved, meeting penultimate whorl at an obtuse 

 angle, reflexed above, forming a callus. 



Major diam. 32, min. 24, height 17 mm. Some shells measure 

 as much as 42 x 31 x 20. 



Hah. The ranges around Mari and in Hazara ; common at 

 Tandiani {Theobald). The original locality was by some error 

 given as " Scind '' ; but the box in the British Museum is marked 

 " collected 10,000 feet above the sea on the Murri Hills, 

 N. Punjab." AVhether P. jiemincii is found east of the Jhelum 

 Eiver is not known. 



The animal differs from other F/<n'«a-like mollusca and much 

 resembles Macrochlamys. The shell-lobes of tlie mantle are long 

 and pointed ; the mucous pore is large, with a distinct overhanging 

 lobe. In the generative organs the male organ is attached to the 

 retractor muscle by a disk-like coil, as in Oxytes orohia and most 

 species of Macrochlamys. Dart-sac large, spermatheca well deve- 

 loped, and a rather large kale-sac. The teeth on the radula 

 are thus arranged : 62 . 3 . 24 . 1 . 24 . 3 . 62 (89 . 1 . 89) ; central 

 tooth tricuspid, those on each side of it bicuspid ; outermost 

 laterals very minute, bicuspid.

Shell depressed, thin, covered with a thin olivaceous epidermis, 

 marked with transverse striae of growth and with fine subobsolete 

 spiral lines, scarcely polished above, more so beneath ; spire low, 

 convex, suture impressed ; whorls 4|, flatly convex above, the 

 last not descending, rounded at periphery and beneath ; aperture 

 oblique. Innately oval ; peristome thin, margins converging, upper
