the Volcano of Apo and its Vicinity. 479 



a. <J . Mt. Apo, 8000 ft., March. No. 273. 



b, c. <J . Davao, March, May. Nos. 308, 454. 



"Iris pale bluish-grey; bill black; feet ashy-brown or lieht 

 slate." 



The examples of the Hairy-backed Babbler from Davao, 

 on the south-west coast, do not differ from the specimens' 

 procured on Mt. Apo at 8000 ft. 



31. ZoSTERORNIS CAPITALIS. 



Zosterornis capitalis (Tweedd.); Grant, Ibis, 1897, p. 233 ; 

 McGregor & Worcester, p. 82. 



a. $ . Piso, May. No. 422. 



b. ? . Mapugba River, May. No. 434. 



Male. " Iris light bright red ; upper mandible dark slate- 

 coloured, lower light slate-coloured; feet light slate- 

 coloured. " 



Female. "Iris light reddish-gold; upper mandible dark 

 lead-coloured, lower pale lead-coloured ; feet pale grey." 

 These specimens agree well with the type from Dinagat. 



32. PsEUDOTHARRHALEUS UNICOLOR. 



Pseudotharrhaleus unicolor Harterr, Bull. B. O. C. xiv. 

 no. cvi. p. 74 (1904) ; McGregor & Worcester, p. 80. 



Pseudotharrhaleus griseipectus Mearns, Pr. Biol. Soc. 

 Washington, xviii. p. 2 (1905) ; McGregor & Worcester, p. 81. 



a,b. S ? . Mt. Apo, 8000 ft., Feb. and March. 

 Nos. 153, 255. 



" Iris dark brown ; bill black ; feet and nails rusty-brown 

 (in the male), dull reddish-brown (in the female)." 



I have no doubt that P. griseipectus Mearns merely repre- 

 sents the adult plumage of P. unicolor Hartert ; the birds 

 procured by Mr. Goodfellow agree perfectly with Major 

 Mearns's description, and I have compared them with the 

 type of P. unicolor, which is undoubtedly in immature 

 plumage. The species is new to the British Museum. 



33. Pycnonotus goiavier. 



Pycuonotus goiavier (Scop.) ; McGregor & Worcester, p. 80. 

 a, b. J ? . Davao, Feb. Nos. 129, 1 13. 

 "Iris, bill, and feet black."
