it as the typical form of the genus. Fortunately, it is immaterial in 
this instance which species is taken, for it is quite clear what group 
of shells Aalella is intended to include, and either three species 
might be taken for the type. I wish one could say this of some 
other genera—Nanina, Gray, for instance. The first two species of 
Mr. Blanford’s genus were included by Albers (‘ Die Heliceen,’ 1860, 
edit. Von Martens) in his genus Trochomorpha; but, as he has taken 
trochiformis, Fér., from the Fiji Islands, as the type, it must be 
exclusively used for species from that part of the world, which are 
not at all likely to be related to these Indian forms; moreover, when 
Trochomorpha was made to hold such very dissimilar shells as fas- 
tigiata, anceps, and serrula, the sooner it was restricted the better ; 
and attegia, infula, cacuminifera, and arv were soon removed from 
it by Stoliczka, the first becoming the type of his genus Conulema 
(J. A. S. B. 1871, p. 236), the second the type of Adams’s genus 
Sitala, which has priority. Drawings of species of this genus I hope 
to give at an early date.

The animal is of a pale colour, with a distinct gland at the ex- 
tremity of the foot, with a well-defined lobe above it. Stoliczka, 
in his description attached to a drawing left to us by him, says— 
‘“T have not seen any mantle-lobes; pinkish grey, tentacles and 
head darker.” In J. A.S. B. 1871, p. 237, the same author writes— 
“The anatomy of H. barrakporensis closely resembles that of 
Conulema, but the dentition is different, that species haying fewer 
teeth in a transverse row and a great number of the median ones 
enlarged, all being squarish, not pectiniform.” 
Locality ? Ex Museum Cuming, now in collection of W. 
T. Blanford, marked an authentic specimen. 
Shell pyramidal, subperforate ; sculpture very fine close-set rib- 
bing, with fine spiral lines on base; colour umber-brown ; spire 
high, conic, sides slightly convex; suture moderately deep; whorls 
53, convex, keeled on last, convex below; aperture suboblique, 
quadrately lunate ; peristome thin, columellar margin subvertical 
and slightly reflected near the perforation.
