ment in separate sacs thus early of the spermatozoa and ova. The 
albumen-gland is covered by the long thin lobes of the liver, is ovoid 
in form, with one flat side. Oviduct as usual. The spermatheca is 
buried in its folds and elongately pear-shaped. The amatorial 
organ is cylindrical, somewhat bent, conforming to the coils of the 
animal’s body, and with the usual muscle-attachment. The penis is 
very peculiar: at a short distance from the generative aperture it is 
like a cecum coiled on itself in a circular or discoid form (fig. 5 5), 
with a short retractor muscle given off from its periphery ; it is then 
free for a short distance to where the vas deferens unites with it, 
and here is an elongate, oval, rather pointed, spindle-like kalk-sac, or 
cecum caleiferum. 
Odontophore (fig. 3). Central tooth elongately triangular, broad 
at base, with two minute denticles on either side ; central cusp very 
pointed ; first laterals broad, with a single small blunt tooth on the 
outer margin at one third its length from the point; tenth and 
eleventh hardly show a trace of this tooth; and all the remaining 
laterals are simple, curved, styliform, and gradually decreasing in 
size.

“This shell, like labiata, monticola, and other Himalayan Helices, 
has frequent varices, the edges of former apertures, distinguished by 
obliquely radiate bands of a darker colour. It was received by Dr. 
J. F. Bacon from Darjiling. A specimen from Dr. Pearson isin the
