from the Sulu Archipelago. 255 



The female, however, is totally different from the hen of 

 E. morio, being uniform grey underneath like the upper 

 surface of the body, whereas E. morio is rufescent below 

 with dusky bars, and has rufous under tail-coverts. Total 

 length 8 inches, wing 4*65 . 



68. Gerygone simplex. 



Gerygone simplex, Cab.; Sharpe, Cat. B. iv. p. 213. 



Two adult females from Bongao, marked : " Bill and legs 

 black ; iris orange-brown." 



These birds appear to me to be absolutely identical with 

 Philippine specimens. 



69. Hypothymis occipitalis. 



Hypothymis occipitalis, Vigors; Sharpe, Cat. B.iv. p. 275; 

 Guillem. P. Z. S. 1885, p. 260. 



An adult female from Bongao, and an adult male from 

 Sibutu. 



70. Rhipidura nigritorquis. 



Rhipidura nigritorquis, Vigors ; Sharpe, Cat. B. iv. p. 334) 

 (1879) ; Guillem. P. Z. S. 1885, p. 260. 

 A pair of adult birds from Bongao. 



71. Zeocbphus cinnamomeus. 



Zeocephus cinnamomeus, Sharpe ; id. Cat. B. iv. p. 343. 



Zeocephus rufus, Blasius, J. f. O. 1890, p. 139. 



An adult female from Bongao, marked : " Bill dark blue, 

 tipped with black ; legs dark blue, nails black ; iris chocolate- 

 brown ; eye-wattle dark blue." 



I suspect that Blasius^s Zeocephus rufus is the same as 

 that now procured on Bongao Island, but the latter is 

 certainly identical with the Basilan bird which I called 

 Z. cinnamomeus, 



72. Rhinomyias ruficauda. 



Rhinomyias ruficauda, Sharpe ; id. Cat. B. iv. p. 368 

 (1879). 



An adult male from Tawi-Tawi appears to be identical 

 with birds from Basilan.
