Characters. This is a somewhat aberrant| genus of the Eurylemide. The high, 
ridged bill projects only half or less than that beyond the frontal feathers. The back of the 
metatarsus is soft in life, rough tin the skin, with noticeable separate scutellae near the base. 
The front is covered with five large scutes. The feathers cover about the basal third of the 
metatarsus, which is hardly as long as the] middle toe. The wing is very broad, the second- 
aries being very long, the tip of the longest primaries not more than about 2 cm. longer than 
the secondaries. The third primary is longest, the fourth hardly shorter or fully as long, the 
second distinctly less, the first much shorter, sometimes not much longer than the secondaries. . 
The tail is slightly rounded, nearly square, about two thirds of the length of the wing. Coloura- 
tion green with black, one species (C. hosei) with the middle of the undersurface blue. Nest a 
rough mass of material, suspended from a branch, eggs cream-colour, unspotted. 
Geographical Distribution of the Species. From Southern Tenasserim throughout — 
the Malayan Peninsula to Sumatra and Borneo.
