CEINIGER. TRTCHOLESTES. 257 



correspond with Tenasserim birds in other respects. In Sumatra, in 

 addition to the present, there occurs another species or race, 

 recognizable by its deep greyish-brown head. It has been named 

 C. sumatranus by Warctlaw llamsay. The Chinese bird was named 

 C. pallidus by Swinhoe ; but I cannot discover that it differs in 

 any respect from (J. yutturalis. 



Distribution. This species appears to be abundant in Tenasserim 

 from its southern extremity up to the neighbourhood of Tavoy, and 

 Bingham records the occurrence of a specimen at Moulmein. It 

 extends down the Malay peninsula to Sumatra and Borneo.

Criniger griseiceps, Hume, 8. F. i, p. 478 (1873), iii, p. 124 ; Hume, 

 Cat. no. 451 bis (part.) ; Sharpe, Cat. B. M. vi, p. 77 (part.) : Oates. 

 S. F. x, p. 209 ; id. B. B. i, p. 183 (part.). 



Coloration. Lores, cheeks, and ear-coverts pale grey ; chin, throat, 

 and upper breast white ; lower plumage ochraceous, tending to 

 buff on the under tail-coverts ; head, crest, and nape grey ; upper 

 plumage with the smaller wing-coverts yellowish green ; upper tail- 

 coverts and tail rufescent ; wings and greater coverts dark brown, 

 the outer webs rufescent ; in birds the plumage of which is much 

 worn the colours are more dull. 



Bill bluish, darker on the anterior half of the culmen and the tip ; 

 eyelids plumbeous ; iris reddish brown ; inside of mouth bluish 

 fleshy ; legs pinkish brown ; claws pale horn. 



Length nearly 9 ; tail 3'8 ; wing 3*9 ; tarsus -85 ; bill from 

 gape 1. 



This species is allied to C. gutturalis, from which it differs in 

 having the upper part of the breast white and the head and crest 

 grey. 



Distribution. The eastern slopes of the Pegu hills from the lati- 

 tude of Thayetmyo to that of Rangoon. The range of the present 

 species probably extends north of these limits. 



Genus TEICHOLESTES, Salvadori, 1874. 



The genus Tricholestes is remarkable for the numerous long hairs 

 which spring from the back. These hairs lie close to the feathers, 

 and are not distinctly visible till lifted up. 



In Tricholestes the bill is very strong for the size of the bird. 

 The culmen is straight for half its length, and the tip of the upper 

 mandible is strongly hooked and notched ; the frontal and rictal 

 bristles are long. The head is not crested. The wing is blunt, 

 the tail slightly rounded, and the feet are exceedingly small and 

 weak.
