keels, but if dry, the shell seems to be "pale ash-colour", in every other respect the specimens 

 agree with the description. The type has been collected at the Andaman-isles.

This common and widely spread species is very variable in many respects, and so I can 

 agree with the views of Tryon, who unites several species with it. I have however found no 

 specimens corresponding to T. fusco-cincta Petit. The colour varies from nearly white (probably 

 bleached) to yellowish-brown and even uniformly rather dark brown, in which latter case the 

 brown sutural band is scarcely perceptible. The whorls are more or less convex; in most cases, 

 but not always, the upper whorls are flatter, the lower ones convex. The sculpture varies in 

 distinctness of the keels, which are more or less granular on one, two or on all the lirae, and 

 this only on the upper whorls or on the whole shell, with many intermediate stages; in conse- 

 quence it is impossible, with so many specimens as I could compare, to separate them in 

 different species, even the specimens from the same locality, are as variable as those from 

 different parts of the Archipelago.
