Spizaetus sphinx. 



Spizaetus sphynx, Hume, Str. F. i. p. 323 (1873). 



A smgle skin of a Sjii^aefiis is in the Museum, with no history attached, which 

 1 feel inclined to refer to S. sjihinx of Hume. It agrees exactly in description, but 

 is larger, being perhaps a female. I can hardly believe, liowever, that the bird 

 can be separated from S. cirrhatits ; but perhaps I have not got Mr. Hume's 

 actual species before me. The broad subterminal bar and preceding interspace 

 occur in young Madras specimens, and in one immature bird from Jsepal.

The general colour of the ujiper surface in this species is a dark umber-brown ; 

 but the base of the feathers of the crest is white, and the margins of the other 

 occipital feathers are of a light yellowish brown. Some of the scapulars and 

 other alar feathers (especially the latter) are slightly tipped with the same ; the 

 tail, which is of a somewhat lighter brown than the back, is tipped with a very 

 narrow edging of white, and is also crossed by seven blackish brown bars, the 

 upper one, however, being somewhat indistinct, and the two lower being sepa- 

 rated by an interval which is twice the breadth of the spaces between the other 

 bars. The throat has a broad blackish band running Aovm the centre, with two 

 similar and nearly parallel bands proceeding from the corners of the mouth, tlie 

 three bands all merging in a cluster of dark-brown lanceolate marks upon the 

 upper portion of the breast, the intervals between these markings, and abo the 

 whole sternal and abdominal regions, being tinged with a yellowish rufous ; the 

 under tail-coverts are barred with brown and white, the former bars being much 

 broader than the latter ; and the thighs and toes are marked throughout their 

 length witli narrow, equidistant, transverse bars of the same colour. Total 

 length 25 inches, crest 24, wing from carpal joint 14|, tail 1 IJ, tarsus 3 j, middle 

 toe and claw 3.
