‘The banded variety which is common at Mussoorie is precisely 
the same in every respect, but not quite so numerous as the other 
described above ; the band is situated just above the periphery, and 
is near 4 mm. in width.” 
Theobald writes under — 
Hemipiecta Monticota, Hutton. 
“Generally distributed throughout the Western Himalayas. In 
the valley of the Bichliri River, an affluent of the Chenab, this 
species occurs remarkably fine and in incredible numbers in the 
fissures of rock, though few live specimens were procurable at the 
time of my visit. The colour of the shell is dark chestnut, both 
above and below, and there are four or five prominent pale bars or 
transverse stripes, marking the seasonal arrest of growth and the 
position of successive epiphragms, formed during the period of 
hybernation. ‘The epidermis is very thin and a pale yellow, and the 
shell does not attain maturity under seven or eight years. The first 
five whorls are minutely shagreened ; the remaining ones smooth, 
but more or less transversely rugose. 
“« My largest specinien measures 47 xX 39x 23mm. The species is 
particularly common below Nachilana in the Bichlari valley.” 
There is a small variety in Mr. Blanford’s collection, also from 
Stoliczka, from Fagu, near Simla, with the same well-marked 
varices of growth ; it has the full number of whorls, but enly 19°25 
mm, in maj. diam.
