dark earthy brown. The wings are of moderate length, the third, fourth, fifth and sixth 
luills being subequal and longest ; tail medium length and rounded at the sides ; tarsus 
short ; feet as in the other genera. 
There are only two species belonging to this strange genus, which differs greatly in per- 
sonal appearance from any other of the family, and, as Mr. Blyth justly remarks, closely 
i esembles the smaller members of the RamphasUdce group. 
I hey are small dingy birds. The bill when seen in profile looks huge in comparison with 
the size of the bird ; but when seen from above, it is not broader than that of a Sylvia. 
•^ome authors consider that the difference is only sexual, and that both come from Sumatra 
(as is the opinion of Mons. Jules Yerreaux). Mr. A. R. Wallace, the latest scientific orni- 
thologist who has visited Borneo and Sumatra, and obtained both species, has no hesitation 
in saying, fiom his own experience, that the red-breasted bird is Bornean, and the yellow- 
breasted Sumatran. I his evidence is sufficient to warrant a separation.
