XIII, D, 6 Zimmer: Birds of Southern Palawan 343 



but the bird shows signs of immaturity and is in rather poor 

 plumage, so that I would hesitate, without a series of sibirica at 

 hand, to place my specimen in that species. There is a single 

 record of sihiHca from Palawan. 



Cyornis lemprieri Sharpe. 



Lempriere's cyornis was not abundant but was rather well 

 distributed and of sylvan habits. My records are from Brooke's 

 Point, Dandelit, Candauaga, and Balabac. Specimens were taken 

 at the first three localities. 



Two of my males are typical Cyornis lempneri, but a third, 

 No. 1445, is indistinguishable from C. philippinensis by the char- 

 acters usually given for the separation of the two species. The 

 orange hue of the under surface of the body is no paler than in 

 my Luzon birds, and while the throat is paler, inclining to 

 whitish, the same character is exhibited in some specimens of 

 C. philippinensis. With this fact in mind I made a comparison 

 of my specimens with the series in the Bureau of Science collec- 

 tion and found the existence of other characters which serve 

 very well to separate the two forms, as represented in the two 

 collections. In all of the males of C. philippinensis the black chin 

 spot is present and well marked. In some of the males of C. 

 lemprieri this spot is also present but never to the extent ex- 

 hibited by the maximum of philippinensis, while it is sometimes 

 entirely lacking. Where it is present, the specimens all possess 

 the lighter tints on breast and throat, as indeed they do in some 

 cases where the chin is not black, but in all cases where the 

 ventral coloration approaches that of C. philippinensis the black 

 chin spot is lacking. In C. lemprieri, also, the sides of the 

 breast average more broadly blue, and in one of my specimens the 

 feathers across the breast are narrowly edged with blue. The 

 females are, of course, unmistakable. 



Cyanoptila bella (Hay). 



On March 28 at Brooke's Point I collected a female of this 

 interesting species at the edge of the forest, where it was con- 

 ducting forays from a perch on a vine-covered stump, darting 

 out after insects and returning to its post in true flycatcher 

 fashion. It was the only one of its species that I saw. 



Collected by Everett in Balabac, and recorded by him in 1895, 

 the Japanese blue flycatcher has not been found since in the Phil- 

 ippines; nor is there any other evidence of its occurence there 

 except the notation by Sharpe in his Hand-list, in which Pala- 

 wan Island is given as a habitat of the species as well as Balabac
