SUTHORA. 107 
Colours of soft parts. Iris brown to red-brown ;_ bill wax- 
yellow; legs and feet slaty-grey or plumbeous tinted with blue or 
green ; ‘legs and claws green” (Cockburn). 
Measurements. Rather smaller than the last; tail about 
100 mm. ; wing 80 to 85 mm.; culmen about 8 to9 mm.; tarsus 
about 26 mm. 
Distribution. Hills south of Brahmaputra, N. Lakhimpur, 
hills of N. Burma, Shan States into western China. 
Nidification. Similar to that of the last bird but probably never 
breeds below 3,000 feet and seldom under 4,000 feet. The eggs 
also are indistinguishable and the average of 34 is 22°2 x 16-4 mm. 
Habits. Tne same as those of flavirostris, but whereas that 
bird is most common at low levels this is found at much higher 
levels and never, so far as has been recorded, in the plains or 
foot-hills. 
Genus SUTHORA Hodgson, 1838. 
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 sh arply 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. he 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.
