Habitat in montibus Arakanensibus provin.ciam Burmanam Pegu

A Burmese representative of the little Darjiling group of Alycati , 
which comprises A. constrictus , B. A. Bvmbex, B. and A. O.tipho - 
rus, B. A. grapliicus , although much more globose than any of the 
others, is in some respects intermediate between constrictus and 
Otiphorus, resembling the first in size and somewhat in form, and the 
latter in the reflexed left edge of the outer peristome. This charac¬ 
ter, however, is by no means so much developed in the Burmese as 
in the Darjiling species. The present has a more marked sculp¬ 
ture than either of its three allies and differs from them also in the 
very slight approximation of the costulation behind the constriction. 
Almost all the species of the genus Alycceus , are more closely and 
strongly marked upon the tumid portion of the last whorl than on 
any other part of the shell, the length of the closer ribbing and of 
the tumidity having a general relation to that of the sutural tube.* 
Several dead specimens of Al graphicus were found at Moditoung, 
a halting-place about 55 miles from Prome, on the road across the 
uninhabited Arakan Yoma range from that place to Tongoop.
