The genus Suthora is one which has been much split up by some Ornithologists. Harington accepted Heteromorpha, Chleuasicus, Suthora and Neosuthora as good genera. Whilst,, however, the last named is sharply divided from the others by its very short tail, I can find no generic differences between the three first and retain them all under Suthora.
The characteristics of the genus are the short, thick bill, a trifle longer than deep, the culmen strongly curved but with the com¬missure almost straight. The nostrils are very small, circular, and completely concealed by plumules. The sixth primary is a little longer than the fifth and seventh or subequal. The tail-feathers are long and narrow and greatly graduated, the outer being about half the length of the central. The plumage is soft and full and there is a short thick crest.
