the Wynaad in SouLhern India that appears undistinguishable. I have also 

 several specimens of a Macrochlamys from the ancient town of Champanir, 

 near Broach, that may very possibly be a variety of M platyclilamys. The 

 specimens are larger than the Bombay types, an adult measuring 16 mm. 

 by 14 in its two diameters, and some individuals attain even greater dimen- 

 sions ; the mouth too is rather more convex beneath, but otherwise the two 

 forms agree very closely. 



The figure gives the idea of a rather thick shell, and the form of the 

 mouth is incorrect, being too convex below and, consec[uently, too high in 

 comparison with the breadth.

Shell openly perforate, turbinate, thin, yellow or fulvous horny, smooth, 

 polished, transparent, obliquely striated, and under the lens finely decussat- 

 ed on the upper whorls with minute, close, impressed spiral lines. Spire 

 subconical, the sides a little convex, apex obtuse, suture slightly impressed. 

 Whorls 5|-6, rather convex, regularly increasing, the last not descending, 

 obsoletely subangulate at the periphery (in immature shells distinctly angu- 

 late), the angle disappearing near the mouth, convex below and radiately 

 striated. Aperture oblique, ovately lunate, broader than high. Peristome 

 thin, straight, the margins approaching each other slightly, columellar
