STACHTRIDOPSIS. 267 



(275) Stachyris chrysaea assimilis. 

 THE BURMESE GOLDEN-HEADED BABBLER. 



Stachyris assimilis Walden, Blyth's B. of B v p. 116 (1895) (Karen- 

 nee) ; Blanf. & Gates, i, p. 163. 



Vernacular names. None recorded. 



Description. Similar to the last bird but without any black eye- 

 streak ; both upper and lower plumage rather duller, below more 

 yellow, less orange. 



Colours of soft parts. Iris deep red-brown or Jake ; bill lav- 

 ender-grey, pinker at the base and on lower mandible; in some 

 specimens dark horny-brown, probably in breeding season ; legs 

 yellowish brown to greenish brown. "Wardlaw-Eamsay records 

 one male as having black irides. 



Measurements as in the others. 



Distribution. S. Shan States and Karenni and probably all 

 the hill-ranges of East Central Burma. 



Nidification and Habits similar to those of the Assam bird. 

 Three eggs sent me from the South Shan States measure about 

 15-3x12-0 mm. 



(276) Stachyris chrysaea chrysops. 

 THE MALAYAN GOLDEN-HEADED BABBLER. 



Stachyris chryscea chrysops Richmond, Proc. Biol. Soc. Wash., xv, 

 p. 157 (1902) (Trang, Lower Siam). 



Vernacular names. None recorded. 



Description. This race has a black eye-streak like the Northern 

 Indian form and has the under parts fairly bright yellow but 

 rather less so than in the typical bird; the upper parts are the 

 same as in assimilis. 



Colours of soft parts and Measurements as in assimilis. 



Distribution. Peninsular Burma and Assam and Malay Penin- 

 sula. The specimens in the British Museum collection from 

 Tenasserim seem referable to this race. 



Nidification and Habits not recorded. 



Genus STACK YRIDOPSIS Sharpe, 1883. 



This genus differs from the last in having the culmen perfectly 

 straight. It seems to be a form intermediate between Stachyris 

 and Mixornis and then leading into Alcippe. In the genus Mix- 

 ornis, however, the nostrils are oval and exposed whereas in 

 Stacliyridopsis they are covered with a membrane somewhat as in 

 the two preceding genera.
