a. $ ad. Kina Balu, March 2, 1887. Wing 137 inches. 



b. ? ad. Kina Balu, April 3, 1887. Wing 13*7 inches. 

 Althoiigh there is scarcely any difference in size, there 



is a marked variation in the colour of this pair. The 

 male is much the lighter of the two, with a good deal of 

 white on the ear-tufts, the wing, scapulars, greater wing- 

 coverts, and end of tail. The female is remarkable for the 

 uniformity of the upper surface, which shows scarcely any 

 white markings. In the character of the light-brown cross- 

 barring both birds are exactly alike. Beneath the male is 

 much the whiter, and has the throat and chest almost 

 similar to the abdomen, the cross-barring being merely 

 rather closer and broader, but the ground-colour is white ; 

 whereas in the female there is a distinct contrast between 

 the throat and chest and the rest of the under surface, the 

 former parts being nearly as dark as the upper surface of the 

 body. The male has the under aspect of the quills much 

 more distinctly banded than the female. Of course some of 

 this light coloration of the male bird may be due to youth ; 

 but it is, in my opinion, quite an adult bird, though not so 

 old as the female.
