AET. 12 BIEDS FEOM ISLANDS NEAR BORNEO RILEY 15 



To Dinopium everetti of the Palawan group of islands in the 

 Philippines, Dinopium raveni bears a certain resemblance, but the 

 latter is smaller, lacks the black barring on the breast, the throat 

 is buffy- white instead of cinnamon, the chest buffy brown with buffy- 

 white shaft streaks instead of cinnamon without shaft streaks ; in the 

 male, the malar stripe is without any red, and there are other 

 differences. 



Dinopium raveni is hardly confined to Eraban, an island that is 

 separated from the main island of Borneo only at high tide, but the 

 short wing-tip seems to indicate that it is more or less local. 



Since writing the above, I have discovered an additional female 

 of Dinopiwn raveni in the National Museum that was overlooked. 

 It is from Tanjong Batoe, northeast Dutch Borneo, collected August 

 25, and is No. 181,841. The feathers of the chest are lighter than 

 in the Pulo Eraban specimen, more of a wood brown, each feather 

 lighter in the center and narrowly fringed with dusky at the tip and 

 with two incipient bars separated by the lighter center along the 

 shaft; the breast and abdomen yellowish white, washed with wood 

 brown, each feather with one or more subterminal bars of dusky; 

 on the middle of the breast there is a single yellowish white feather 

 crossed by two subterminal blackish bars; otherwise it is much like 

 the Eraban specimen. It measures : Wing, 119 ; tail, 81 ; culmen, 26.5.

 23. CYORNIS BECCARIANA BECCARIANA (Salvador!)

 (Sarawak). 



One adult female and one immature female, Pulo Raboe Eaboe, 

 May 4 and July 27. 



Raven took two adult males on the opposite shores of the main 

 island of Borneo (Segah River and Sungei Ritan). The female 

 from Raboe Raboe, belongs without much doubt, to the same form 

 as the males. 



The above female from Raboe Raboe is indigo blue above 

 from the bill to and including the tail and the outer aspect of the 

 closed wing; the lores whitish; the auriculars bluish black; below 

 ochraceous-orange, belly whitish. The males are indulin blue on 

 the head shading off into dusky blue on the back, or, in some posi- 

 tions, even eton blue, especially on the rump. 



From the above it will be seen that the female is only a duller, 

 duskier blue above than the male.
