SPECIES PREVIOUSLY DESCRIBED. 57 



D. cinereigulare. Chin and upper throat yellow. 8ides<of throat and 

 lower throat grey washed witb yellow. Breast brilliant orange nearly 

 equalling that of D. dorsale in intensity. 



D. assimilis. Rump heavily washed with yellow. TJproat ashy 

 MUCH DARKER than in D. sibuyanica.- Breast tinged with orange. 



D. sibutense. Throat uniform with head. Lower back and rump 

 slightly washed with olive. 



Bach of these species is, so far as we know, confined to a definite 

 area so that no two overlap. 



Prionochilus quadricolor Tweed. 

 Prionochilus quadricolor Tweed.; Sharpe, Cat. B. Brit. Mus. x. p. 70 (1885). 



This fine species is not uocommon in the forest of Cebu but seems 

 never to be found in open country, and as the small amount of forest 

 remaining on the island is rapidly being cleared away we fear that 

 P. quadricolor will become extinct before many years if, as seems 

 at present possible, it is confined to the island of Cebu. 



We are now abje to furnish descriptions of the adult female and 

 young. 



Adult female. Above brown, head faintly washed with olive. 

 Back, wing-coverts and outer webs of secondaries heavily washed 

 with olive yellow. Rump almost entirely of the latter color. Entire 

 under surface greyish white faintly tinged with olive yellow, lighter 

 along center of breast and abdomen. Under wing-coverts, axilla- 

 ries and inner webs of quills pure white. 



Young male like female but lacks yellow wash on outer webs of 

 secondaries, the wing and tail being black as in adult male. 



Prionochilus modestus Hume. 

 Prionochilus modestus Hume. Str. F. p. 289 (1875). 



A series of birds obtained by us in Palawan most nearly agree with 

 the above species and are provisionally so identified pending com- 

 parison. 



Zosterops ever6tti Tweed. 



Zosterops everetti Tweed.; Gadow, Cat. B. Brit. Mus. ix. p. 163 (1884). 

 Zosterops basilanica Steere, List B. & M. Steere Exped. p. 21 (1890); id. 

 Ibis, 1891, p. 314. 



After examining a large series of birds from Cesbu, Samar, Min- 

 danao, Basilan, Sulu and Tawi Tawi we have come to the conclu- 

 sion that there is no ground for separating the birds from the south. 



The specimens collected by the Steere Expedition were obtained 

 in the month of November while those from Cebu, Leyte and Samar
