PALUDINIDiE. 895 



faintly stained with brown, by the almost entire apparent absence of coloration 

 on the last whorl, especially in the absence of the second broad band within the 

 aperture. Unfortunately, all the specimens have lost their opercula. The specimen 

 figured in the * Con. Indica ' is a very old decollated one.

Specimens of this very handsome species from Ava, Pegu, and Mandalay are 

 in the Indian Museum; it is well characterised by its seven produced and solid 

 whorls, acute and prominent spire; the Ava specimens are not decollated, though 

 quite adult ; those from the other two localities have, however, all lost their first 

 three or four whorls ; both young and old shells are perfectly smooth, with the 

 exception of a deeply incised spiral groove below the suture ; the figure in the 

 ' Con. Indica, ' pi. 108, fig. 8, is excellent ; perhaps it scarcely shows sufficiently 

 clearly the three broad spiral brown bands; from the peculiar thickness, even 

 of young shells, these bands are, however, often scarcely visible. The oper- 

 culum resembles that of P. regulata, Bens., only it is little flatter ; both differ 

 considerably from that of P. andersoniana, being much smoother on their inner 

 side.

Shell small, very thick, spire depressed, in shape closely resembling the Euro- 

 pean Litorina ohtusata ; only two whorls, the others decollated in both young and 

 old specimens ; smooth, with a few irregular striae at the suture ; columella very thick, 

 pure white ; aperture somewhat compressed, as in typical P. laUosa, not globosely 

 expanded as in P. hlanfordiana ; in all the ten specimens found, only three instead 

 of four bands, the upper one exceedingly broad, covering nearly half the last 

 whorl, the middle one narrow, the basal one broad, but not diffused over any part 

 of the columella ; these bands are of the most intense black within the aperture, 

 even in very old, thick specimens ; epidermis unusually thick, dark olive-green, 

 closely covered with regular raised pustules of a lighter colour.

The operculum is Uke that of P. regulata, a shade darker in colour, nucleolar 

 portion on the inner side a little more distinctly spirally rugose. The broad and 

 richly coloured bands (only three in number), pure white columella, and pecuhar
