Original description : " H. testa orbiculato-depressa, albo- 

 fucescente, obscure striata, late umbilicata ; ultimo anf ractu cylin- 

 draceo ; apertura ovato-rotundata ; margine albo, reflexo ; peri- 

 stomate continue." (Deshayes.) 



Two specimens labelled: Anamullay Forest, Nilgiries 

 forming part of the Cuming collection in the British Museum, 

 enable me to supplement the foregoing brief diagnosis. 



Shell moderately umbilicated, depressed-conoid, finely striated, 

 here and there showing traces of minute spirals ; whitish, be- 

 coming pale fawn-coloured on the last whorl, mouth dark fuscous ; 

 unicolorous or variously ornamented with dark or pale brown 

 bands. Whorls 5|, .convex above, flattened below, increasing 

 rather rapidly, the last dilated towards the mouth. Spire de- 

 pressed, apex obtuse, suture rather deep. Aperture elliptic- 

 ovate, margins approaching, united by a thin callus on the 

 parietal wall ; peristome somewhat thickened ; upper margin 

 broadly expanded, scarcely reflected, with an acute edge, regularly 

 curved ; outer margin curved, expanded and slightly reflected, 

 basal margin strongly reflected, straight, columellar margin 

 ascending, broadly triangularly dilated and overhanging the 

 moderate umbilicus, which shows half of the penultimate whorl, 

 when it suddenly becomes contracted. 



Major diam. 21, minor 17, alt. 12 mm.

 bank) ; Trichinopoly (Stoliczka) ; Anamullay Forest, Nilgiries 

 (Mus. Cuming). 



Like several other species of the subgenus Trachia, P. proxima 

 exhibits bands variable in 'size and number. I have not seen any
