Contributions to Indian Malacology. 
Lately, however, during a hurried search at Akouktoung, I had the 
good fortune to find some living specimens of what, I have little 
doubt, is the same species as that which I first obtained, the only 
difference being the absence of any sculpture except on the tumid 
portion of the last whorl. From those specimens the above descrip¬ 
tion has been corrected. 
A. Tiumilis resembles somewhat the minute A. armillatus , B. but 
differs in the very much greater distance to which the strongly 
marked costulation upon the tumid portion of the last whorl is car¬ 
ried back from the constriction, the distance being in both species 
proportional to the length of the sutural tube. A. Tiumilis is fur¬ 
ther distinguished by its longer constriction, by the descent of the 
mouth, and the greater tumidity of the last whorl. The colour, as 
in many Alyccci , is probably not quite constant, some specimens being 
white and translucent. 
With A. Tiumilis at Myanoung I found a single broken specimen 
of another Alycceus which resembles the singular little Darjiling A. 
plcctocTieilus in the form of the peristome. The specimen being im¬ 
perfect and weathered, I delay publishing a description of it in the 
hopes of succeeding in obtaining better specimens before doing so.*
