 1910. [W.G.; & Nos. 1186, 1187, 1210, 1305, 1322, 1331, 

 1377, 1421, 1446, 1447, G. C. S.] 



o. S imm. Canoe Camp, 21st Dec. 1912. [C. B. Z.] 



Iris brown ; bill black; legs slate-colour. 



Total length in the flesh about 170 mm. (=6| ins.). 



In the adult males the patch o£ white on the throat varies 

 greatly in individuals ; in one example (No. 1421) it is 

 represented by a few partially white feathers, and in another 

 specimen, also procured by Mr. Groodfellow on the Wataikwa 

 River, the white is reduced to a small spot. 



Messrs. Rothschild and Hartert (op. cit. p. 508) have 

 described a bird from the Upper Setakwa River which 

 they believe to be the unknown female of this species, 

 but it does not agree with the adult females in the series 

 listed above. These resemble the male, but are not of 

 quite so brilliant a yellow on the back and underparts. 

 Mr. Rothschild's specimen may be a quite young example, 

 for in a young male (No. 1377) some of the feathers of the 

 crown are slightly edged with pale olive. 



In younger males and females the back is washed with 

 olive, and the black wing-coverts and upper tail-coverts are 

 more or less fringed with the same colour. 



This fine species is new to the British Museum. 

 " Chunggat, one of the Dyaks who was at Wataikwa, 

 told me this Golden-yellow Thick-head usually frequented 

 the banks of reeds and rough stuff growing in the wide 

 stony bed of that river." — C. H. B. G.
