SYKES : NON-MARINE SHELLS FROM THE EAST INDIES. QI 



Papuina laneeolata, Pfr. 

 var. pulehrizona, n. vai\ 



Shell similar in shape to the typical form, but a trifle more elevated and the 

 lower margin of the peristome a little more curved. Colour pattern of the 

 base precisely as in the type, but there is a broad zone of a chestnut colour 

 above the periphery leaving a narrow white zone both above and below it, 

 the upper white zone being seen on earlier whorls. 



Hah —Obi. 



I think this is only a colour mutation, but as seen from above, it looks 

 quite a distinct species. My specimen is not quite so beaked as the typical 

 form, but this is probably not a constant character. 



Pepriepia eanefriana, n. sp. 



PI. ix, figs. 3, 4. 



Shell sinistral, spire elongate and gradually tapering towards the apex, trun- 

 cate, uniform dark chestnut brown in colour, somewhat polished ; sculpture 

 well marked lines of growth ; whorls remaining 7, plano-convex, regularly 

 increasing to the last whorl, very little, if at all, ascending in front ; aperture 

 somewhat pyriform, dusky brown within, peristome whitish, continuous, 

 somewhat thickened, the outer margin a little expanded, and the columella 

 rather twisted and truncate. 



Alt, 24.5 ; diam. max. 6.4 : alt. apert. 7.3, diam. apert. 5 millim.

This interesting discovery extends the range of the genus, hitherto known 

 only from New Guinea. The present species is by far the smallest of the 

 three described and may be separated from P. minor, Smith, by its darker 

 colour, more tapering form, and by the columella being more twisted. As 

 Mr. Pilsbry states *^' "the internal structure of the shell has not been investi- 

 2;ated," I have broken up a specimen, which is now figured. The axis is 

 much twisted, and I am unable to trace any armature upon it. I doubt if 

 Perrieria belongs to the Mri/asiiiriilae ; may it not be really referable to the 

 Achatinidae ? 



Leptopoma ponsonbyi, n. bp. 

 PL ix, fig. 15. 



Shell turrited, moderately umbilicated, obscurely marked by lines of growth, 

 microscopically densely spirally striated, with a number of small filiform 

 carinae, five on the last whorl but one, these carinae being most numerous 

 in the umbilical region ; colour horny brown with a pale zone just below 

 the suture, this zone being marked with irregular blackish-brown blotches ; 

 whorls 5I, convex ; aperture round, duplex, the outer portion very widely 

 expanded except on the columellar margin, flattened, bending a trifle back- 

 wards and the surface a little wrinkled. 



Alt. 8.3 ; diam. max. (with lip) 8 millim.
