microscopically sculptured protoconch. Suter himself has drawn 
attention to the very characteristic apex in which the present spec¬ 
ies difTers from all other Mangiliinae so essentially in its coarse 
revolving ribs, that the creation of a new genus for its reception 
seems well founded. This peculiar protoconch places this genus in 
a section of its own, differing as well from the smooth tipped Man¬ 
giliinae as from the Daphnellinae with their minute spiral or elabo- 
rate sculpture of the protoconch. Liracraea may besides this type 
of the genus comprise the similarly equipped Mangilia devia of 
Suter, which, however, I had no opportunity to examine.
