This is a somewhat anomalous genus among the Erirhininae 

 owing to its pectoral canal which, however, as in yì«èeow?/7«?^.s, 

 a genus in the same group, does not extend beyond the an- 

 terior coxtt'. The ex))onent of this genus exemplifies certain 

 sexual distinctions going to show how uncertain may be the 

 characters when taken from a single specimen only. In what, 

 from its shorter rostrum I take to be the male, the scrobes 

 begin from one quarter to one third the length of the rostrum 

 from the apex, and up to that point there are five well-marked 

 elevated lines, or cari me , the intervals filled with pale silaceous 

 scales. In the female the i-ostrum is much longer, apparently 

 .smooth and polished throughout, but in some lights faint striae 

 may be detected, and the scrobes begin in the middle ; the eyes 

 are also less roundeil. There is no doubt as to their specific 

 identity.
