" A Burmese representative of the little Uarjiling group of 

 Alyccei, which comprises A. consirictus, B., A, bembex, B., and 

 ^•1. otiphorus, B. A. (iraphicus, although much more globose than 

 any of the others, is in some respects intermediate between 

 constrictus and otiphorus, resembling the tirst in size and some- 

 what in form, and the latter in the reflexed left edge of the outer 

 peristome. This character, however, is by no means so mucli 

 developed in the Burmese as in the Darjiliug species. The 

 present has a more marked sculpture 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 Ahjcams 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.'' (BJcuifonl.)
