The three males in the Buo series were all courting 
the female. 
Surniculus lugubris resembles very strikingly one of 
the smaller Dicruridae in the nest of which it is said to 
deposit its eggs. The likeness is so strong that usually 
I was not sure which of the two I had shot, till I picked 
up the bird. 
112. Hierococcyx bocki Wardlaw Ramsay. 
22 imm. Suban Ajam, Redjang, Bencoolen, 
1000 M. July [Nos. 525, 529]. 
Wings 188, 190 mm. : 
The crown of the older bird is very dark grey, of the 
younger grey and rufous ; the latter has the back and wings 
dark brown clearly barred with pale rufous ; the sides of 
the neck and the breast are much suffused with rich rufous, 
the anterior underparts are longitudinally striped with dark 
brown, the posterior parts transversely barred with the 
same colour. The upper parts of the older bird are 
obscurely barred and it has much less rufous on foreneck 
and breast.

Subad. Iris pale yellow, eyelids yellow, orbital skin 
yellowish green, upper mandible brownish black, base and

and tip brownish, feet and claws chrome. 
Imm. Iris greyish yellow or dark grey with brownish 
inner ring, orbital skin lemon, upper mandible blackish, 
base greenish yellow, tip yellowish or brownish, lower 
mandible greenish yellow, tip blackish, bill interiorly 
yellow, feet and claws chrome. 
Wings, ¢ 175; @ 178, 172 (imperfect) mm. 
Two forms of this species are reported from the Sunda 
Islands, H. f. fugax (Horsf.) from Java, a resident ; and 
H. f. nisicolor (Blyth) from Nepal, a visitor : the latter is 
stated to have a smaller bill. The bill of the older of the 
above birds, taken in March, is certainly a trifle shorter 
than the others (about 1 mm.), but there is hardly sufficient 
difference between them to consider that the series repre- 
sents two subspecies. Until these specimens have been 
compared with topotypes of nisicolor their exact determina- 
tion must remain unsettled.
