obsolete longitudinal furrows ; shell wide, polished, thick and 

 opaque. Aperture subquadrafce, margins thickened and subre- 

 flected ; varying from ^ to j-f- inches in length. Animal dusky ; 

 ovo-viviparous. 



" Var. A. This is in all respects a perfect miniature of the 

 foregoing, but it never seems 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 

 Afghanistan. 



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

 seldom exceeding T 7 ^- 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 defined. 

 Whorls usually seven in number, rarely eight." (Button.) 



Specimens from Kutch, presented by A. T. Daniel to the 

 British Museum, possess 9| whorls and measure 16x5 mm.; 

 others, composed of eight whorls, only reach u length of 14 mm., 

 with a diameter of 5 mm.

Apparently a rare species, which differs from Z. insularis in 

 being smoother and in having the later whorls distantly radiately 

 plicate-striate ; the aperture is also a little more transversely 

 elongate.
