This specimen, except for the bars on the tail, is 
blackish-brown throughout, slightly darker on head and 
sides of neck: it is crestless. Except for size it can be 
exactly matched by an unsexed example from Kuala 
Lumpur with a wing of 415 mm. It is the largest specimen 
we have seen, no other bird in our considerable Malay- 
sian series having so long a wing, the range being (twenty 
examples) 403-432 mm. 
It undoubtedly represents the East Siberian form 
Pernis aptvorus orientalis Taczanowski (Faune Orn. Sib. 
Or. I, 1891, p. 50), which Stresemann states visits the Sunda 
Islands in winter.

Iris golden yellow, upper mandible horn black, lower 
mandible dirty white, tip blackish, cere black, feet chrome, 
claws black. 
Contents of stomach : chrysalides of bees.

Measurements in the flesh—é No. 232, total length 
588, tail 275, wing 416, bill from gape 40, ts. 50 mm. 
Both these birds have well-developed crests. The 
second is in the phase named Pernis tweeddalei by Hume 
(cf. plate, Stray Feathers, X, 1887, p. 513): the other is 
younger and not so dark, with shaft stripes on the breast, 
the abdomen barred white and brownish rufous and a 
brownish rufous collar. 
We have little doubt that the various forms of honey- 
buzzard are only geographical races of P. apivorus, the 
northern subspecies being crestless while the southern ones 
develop a crest.
