Guimaras (Bourns & Worcester); Negros (Bourns d Worcester, Whitehcad.) 



"Adult male. General color above ochraceous brown, duller on head, 

 much brighter on rump, becoming chestnut on the tips of upper tail- 

 coverts; upper wing-coverts like back; quills nearly black, washed with 

 rusty brown on outer webs, this wash changing to whitish on the prima- 

 ries; upper surface of tail dull chestnut, the feathers becoming almost 

 black at tips; lores gray; ear-coverts and sides of hind neck like crown ; 

 a ring of feathers round eye slightly lighter; chin and entire throat 

 white; entire breast light olive-brown; flanks washed with same color; 

 abdomen pure white; under tail-coverts white, light brown at tips; 

 under wing-coverts, axillars, and inner webs of quills buffy white; bend 

 of wing olive-brown. 



"The white throat contrasts strongly with the brown of neck and 

 breast and at once distinguishes this species from all other Philippine 

 representatives of the genus. R. albigularis is a deep woods form and 

 is extremely rare in the localities visited by us." (Bourns and Wor- 

 cester.) 



"One of the most interesting birds sent from Negros is this white- 

 throated flycatcher, very nearly allied to R. pectoralis, which inhabits 

 the south of the Malay Peninsula, Sumatra, and Borneo. The present 

 species may, of course, be distinguished by its considerably larger size 

 and the absence of the white patch in front of the eye, as well as by 

 the more olivaceous brown cheeks and chest-band, which are not so 

 strongly contrasted with the white of the throat. But these differences 

 are really slight, and it seems very curious that the Negros and Gui- 

 maras birds should so closely resemble R. pectoralis from Borneo, while 

 we find two distinct but closely allied species, R. ruficauda and R. ocula- 

 ris, occurring in the intermediate islands. In Prof. Steere's collection 

 we have received the types of R. samarensis as well as two specimens 

 collected at Ayala, Mindanao, which he considers to represent an un- 

 described species. They apparently differ from his R. samarensis only 

 in having the culmen reddish brown instead of blackish brown ; but this 

 difference is due to immaturity, as is further proved by the subterminal
