form by its larger size (on an average) and greater depression 
(maximum breadth 34 mm., depth 17 mm.). I found several dead 
specimens of this shell on the northern slope of the hill at differ- 
ent altitudes and there are others in the Indian Museum from 
Stoliczka’s collection. The typical form is widely distributed in 
Bengal, the northern part of the Madras Presidency and Central 
India.

This snail, which was doubtfully attributed to M. lecythis 
(a species found on the Rajmahal Hills) by Stoliczka, is appar- 
ently endemic on Parésnath. I found numerous individuals, 
most of them immature, on the north side of the hill at altitudes 
of from 4,000 to 4,500 feet. They were aestivating under stones 
at the time of my visit (April, I910) and had their shells closed 
by a wad of dried slime, but on being brought into the moister 
climate of Calcutta they resumed active life.

Numerous specimens of this snail were found together with 
those of M. sacrata in similar circumstances and condition. The
