No. 7 comprises an enormous area, in which the Alyccei differ 

 considerably from those on the west (previous Sections 1-6). Only 

 the hills near the Irravadi below Mandalay above and up to Bamao 

 may be said to have been collected in. In the Shan States collect- 

 ing has been very desultory, the limestone formation of that part 

 would yield a fine harvest of very interesting forms. Nothing is 

 known of the mollusca of the hill country west of the Kyengdwen 

 in the Chin and Lushai Hills, or norihward at the head of that 

 river. South we have but few from the Sittoung and Salween, 

 by no means what might be expected to occur.
