Shell im perforate (sometimes apparently subperf orate 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 ; whorls 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 42x31x20. 



Hob. 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." Whether P. flemingi is found east of the Jhelum 

 River is not known. 



The animal differs from other Ft*nna-like mollusca and much 

 resembles Macrochlamys. The shell-lobes of the 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 Ox-ytes orobia 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.

sp. 17. 



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
