1S72.] FROM JXORTHEEN BORNEO. 219 



Eagles, being about equal in size to »S'. mfipectus, Gould. The adult plumes that have appeared 

 on the thighs, under the shoulders, and on the abdomen and flanks are much paler than in my 

 Malaccan, Javan, and Cingalese examples of S. hacha. I am inclined to the opinion that it 

 belongs to a distinct and undescribed species ; yet, until a fully adult individual can be examined, 

 I propose to regard these Borncan birds as representing S. haclta in immature plumage. If it 

 eventually proves to be distinct, I venture to suggest for it the title of Spllornis pallidus. 



Two examples are sent by Mr. Everett, one without a label. One marked " Jambusan, 

 September, ? ," is of a young bird in transition plumage. The feathers of the interscapular 

 region are pale rusty fulvous, with a broad subterminal dark brown band, which is fringed with 

 albescent fulvous. On the lower back and uropygium the feathers are pale brown, terminated 

 with deeper brown and fringed with albescent-fulvous. The feathers of the head including the 

 crest, which is considerably developed, are white at their insertion, then tawny, with a dark 

 brown subterminal, drop with a terminal fringe, much decomposed, of albescent-fulvous. Below 

 each eye a bold pure white mark ; a narrow black line over the eye, joining the black ear-coverts 

 and cheeks ; chin and throat immaculate tawny. The remainder of the under surface tawny. 

 Some of the pectoral plumes with pale brown central triangular markings ; lower down some 

 with faint central streaks of pale rusty brown. Abdominal and ventral plumes, the thighs and 

 tail-coverts, and the flanks with numerous cross bars of dilute ferruginous. Axillaries barred 

 with bright pale ferruginous. The primaries are brown above, with black outer webs, deepening 

 towards the tips, which are white, and one or two slanting black bars crossing both webs. 

 Underneath the quills are white, the black bands and ends showing through as pure or mottled 

 pale brown. The rectrices at their base are brown ; then a band of very dark brown an inch and 

 a half deep, followed by a still broader pale band of albescent brown ; then a narrow subterminal 

 very dark brown band, edged by a very narrow border of light brown, and Anally fringed with Ibis, 1S72, 

 albescen t. P- ^^'^■ 



The second example, which (from its smaller dimensions) is probably of a male, has put on 

 many of its adult feathers. The chin and throat white, with a few feathers brown-centred. The 

 remainder of the under surface of the peculiar pale earthy brown colour foimd in S. cheela. The 

 breast unspotted, but the abdominal, ventral, and flank feathers, the axillaries, under wing-coverts, 

 thighs, and under tail-coverts more or less spotted with pure white ; the axillaries have their 

 ground-colour more ruddy. The under surface of the quills as in the Jambusan individual ; 

 above the black portion of the quills as in that example, but the paler brown replaced by 

 pale earthy brown mottled with albescent. The banding of the rectrices is different and very 

 irregular. The subtermimal dark brown band both individuals possess in common; the pale 

 band above is narrow, irregular, and mottled. Above this, again, the dark brown band occupies 

 less space, and is broken into by mottled pale brown and albescent, above Avhich, again, are indica- 

 tions of a third dark brown band. The plumes of the head and crest are mostly pure white at 

 the base, terminated with a broad jet-black band. The white mark under the eye persists ; but 

 the cheeks and ear-coverts are cinereous, with a jet-black shaft to each feather. The back and 

 wing-coverts are of a much paler brown.
