 edges obscurely crenulate ; anal orifice circular, close to the 

 bases of the lobes ; the usual incisions (two on each side), 

 with thickened edges ; spines very small ; squames large, 

 narrow, but branched, extending a little beyond the lobes ; 

 two squames between the lobes, about eleven on each side 

 beyond the lobe, placed close together.

 lobes separated by a moderate interval, obliquely truncate, 

 with rounded corners ; plates very inconspicuous ; margin 

 beyond the lobes serrulate, with three or four small promin-
