adult, and a very old female will show the frontal "hairs'"' just 

 as stront^ly developed as iu the old male, but the curve of 

 the tail is never so strongly marked in the hen as it is in the 

 male bird. The non-development of the frontal hairs and 

 the white spots on the under wing-coverts are sure signs of 

 immaturity, and as the latter disappear in the progress towards 

 maturity, so are the frontal hairs correspondingly developed. 

 It is remarkable to see how long traces of the white spots 

 on the under wing-coverts are preserved, even when the birds 

 are otherwise in beautiful plumage. Very old individuals, 

 however, are absolutely unspotted on the lower surface of 

 the wing. 



[The iris is lake, bill and feet black. Like its relation 

 Buchanga st'igmatops, this Drongo prefers the neighbourhood 

 of clearings made by man, Avhere no doubt the food-supply 

 is greater than in the thick forest. It frequents, however, 

 the more open places in the latter up to about 5000 feet. I 

 found several nests near the Dusan "campongs" containing 

 two eggs, which were of a very pale salmon-pink, dotted all 

 over with reddish spots and underlying grey spots and mot- 

 tlings, chiefly collected near tlie larger end. Length I'l- 

 1'15 in., diam. 0*8-0'85. One nest was taken on the 20th 

 of March, 1888, and another on the 20th of May. After 

 the manner of Drongos the nest is placed at the end of a 

 long bough at no great height from the ground ; it is a shallow 

 structure, consisting of roots neatly twisted round the fork 

 of a slender bough. Dusan name '^Limbas.'']

This species was described by me from Kina Balu in 1879, 

 when Mr. Burbidge met with some specimens. I have no- 

 thing to add to the remarks I then made (/. c.) . The males 

 measure 4*75-5"l inches in the wing, and the females from 

 4' 8 to 5" 15 inches.
