 p. 410. The CRESTED JAY, 



Whole head, crest, chin, throat and entire lower plumage black ; back, 

 scapulars, wings and wing coverts, rump and upper tail coverts rich olive 

 brown ; tail dark brown ; a large patch of white on either side of the neck, 

 two white patches of the same at the back of the eye. The young is paler 

 brown, the forehead greyish, lores whitish, the white patch behind the eye and 

 on the neck, margined with blackish ; wings reddish brown ; under surface of 

 body slaty ; bill and legs black ; irides reddish brown. 



Length. II inches; wing 5-5 ; tail 5 ; tarsus 1-3; culmen 1-35. 



Hab. The Malay Peninsula, and Tennaserim. 



The Crested Jay has been met with in Tennaserim by Mr. Davison, and Gates 

 procured several specimens at Malewoon. Davison says it occurs only in the 

 evergreen forests of the extreme south of Tennaserim. It is a restless bird 

 flying from tree to tree and branch to branch incessantly, sometimes close to the 

 ground ; and sometimes high up. Even when seated it appears to be unable 

 to keep the body quiet, but keeps bobbing and bowing. 1 1 always keeps its crest 

 fully erect, and as Dr. Stolickza remarked, it looks like a gigantic Lophophanes, 

 Its note is very peculiar, and once heard not easily forgotten. It is a sharp, 

 clicking metallic rattle. The food is believed to consist entirely of insects, 

 such as beetles. It is almost always seen in pairs. 



Platylophus coronal us is recorded from Southern Borneo. 



Gen. Cochoa. Eodgs.
