This species is closely allied to H. boans, Daud., from 
which it differs chiefly in having a smaller tympanum, 
smaller choane, and much smaller and weaker series of 
vomerine teeth.

The chief characters of the species that I suggest for 
separation as a new genus under the above title are the 
straight culmen, not arched or semicircular as in Sporophila, 
and the more rounded tail; its small size and peculiar colora- 
tion also help to distinguish it. 
Type, I. castanetventris (Cab.).
