blunt angulation is persistent. NV. bajadera, too, has a fine vitreous 
lustre, while intwmescens is dull; and the former shell is usually of 
a greenish-olive colour, though varying in this character, and some- 
times resembling the latter. The animals also show a difference in 
colour: that of IV. intwmescens is uniformly, so far as I have seen, 
dark cinereous, while that of bajadera is much lighter, but very 
variable. The latter shell is found mostly on shrubs, the former 
on the ground ; and while intwmescens has as yet only been found at 
Mahableshwur, 4500 feet above the sea, bajadera (which is rare 
at’ Mahableshwur) abounds on the equally or nearly equally high 
hills of Singhur and Poorundhur, and along the summit of the 
Western Ghats at about 2000 feet. It abounds at Khandalla at 
the top of the Bhore Ghat. 
«7 have already mentioned in a previous paper (Ann. Mag. Nat. 
Hist. for February 1863) that an examination of the type specimens 
of NV. bajadera, Pfr., and NV. ammonia, Valenciennes, has showed 
these two supposed species to be identical. 
“T long doubted the distinctness of the species now described 
from IV. bajadera; but although I have specimens of the latter from 
many different places, they are all easily distinguished from J. 
intumescens.” 
The teeth are similar to those of A. enterrupta, var., but the 
median teeth have a decided small tooth on the inner margin, ren- 
dering them tricuspid; the laterals are long and narrow and gradually 
become very small on the outer margin, and are more numerous.
