Fig. 202. — Cassidix oryzivora. ■ 



This genus is easily recognised by the flattened culmen on its 

 posterior portion, where it assumes the form o£ a frontal plate, 

 and the elongated feathers on the sides o£ the neck. The short 

 velvet-like feathers at the back of the nostrils are present as in 

 Cassicus. The bill is long and sharply pointed, the width and depth 

 at the base being nearly equal to half the length of the cuhnen. 

 The wing is slightly pointed, the first primary being longest, the 

 second 5 mm. shorter, the third 8 mm. shorter, and the fourth 

 19 mm. shorter than the first. The tail is rounded at the tip and 

 about two-thirds the length of the wing. The tarsus, which 

 jexoeeds the length of the exposed culmen, is equal in measurement 

 to the middle toe and claw. Coloration : male and female simiLtr.
