654 Notices of some Land and Fresh Water Shells [July, 



scored with obsolete longitudinal furrows ; shell nude, polished, thick 

 and opaque. Aperture subquadrate, margins thickened and subre- 

 flected ; varying from \\ to if inches in length. Animal dusky ; 

 ovo-viviparous. Buries itself in the earth beneath rocks, trees, &c. 

 stopping the aperture with a thin plate of hardened viscous matter. 



Var. A. — This is in all respects a perfect miniature of the foregoing, 

 but it seems never to have more than eight whorls, and seldom exceeds 

 ^ an inch in length ; it is far less ventricose, and generally shows the 

 obsolete longitudinal furrows more plainly. This variety occurs both 

 in India and near Quettah in Afghanisthan. 



Var. B. — With the general sculpture of the last, but shorter, seldom 

 exceeding T ?-g- of an inch ; whorls ventricose and spire more suddenly 

 obtuse than either of the foregoing ; with scarcely more than half the 

 length of P. Indica, it still rivals it in breadth, and the longitudinal 

 furrows appear to be constant and better denned. Whorls usually 

 seven in number, rarely eight. 



The exuviae of all three may be seen in abundance scattered over 

 the sands of the Bhawulpore district. 



10. — Pupa ccenopicta, (Hutton,) J. A. S. Vol. III. p. 85, No. 7. 



Animal blackish. 



Shell cylindrico-pyramidal, with 6 whorls, minutely striate ; body 

 whorl ventricose, the others gradually tapering to an obtuse apex ; 

 aperture ovato-lunate ; lips subreflected and white within ; a single 

 tooth at the junction of the outer lip with the body whorl ; colour 

 brown. Length T \ inches. 



In living specimens the shell is often painted over with a coating of 

 mud, which assimilates it so much to the colour of the rocks it inhabits, 

 as to render it difficult of detection. It was discovered by me in 1832 

 adhering to the face of a bare rock at Beeana near Agra, and again at 

 Neemuch in 1834, adhering to the bricks of a ruined temple. Mr. 

 Benson has likewise taken it beneath stones at Delhi, but in such situa- 

 tions it is destitute of its coating of mud. 



It occurred in Afghanistan beneath stones at Dusht-i-be-dowlut. 



In the single tooth at the angle of the mouth, it makes an approach 

 to Pupa umbilicata, (Gray) of England, but it differs altogether in 

 shape ; in being larger, less abruptly obtuse and more tapering.
