Northern Portion of the Malay Peninsula. 
still smaller size, wing about 1P5, tail about 7*8 inches, and by 
having the sides of the head not grey but rich rufous and 
the under surface also more chestnut. There is an adult 
male and. two somewhat younger males from N.E. Borneo 
(Colls. Hose and Everett ) in the British Museum.

Cerchneis tinnunculus (Linn.) ; Sharpe, tom. cit. p. 425. 
Tinnunculus saturatus Blyth, Journ. Asiat. Soc. Bengal, 
xxviii. p. 277 (1859). 
We obtained a single immature female of the Kestrel at 
Langkawi in November 1907, and Dr. Abbott (fide Rich¬ 
mond, in litt.) procured an adult female in Trang on 
January 17th, 1897. Our own specimen is in extremely 
worn plumage and somewhat bleached, and it is therefore 
difficult to say whether it is merely a migrant from more 
northern localities or a specimen of the resident tropical race 
described by Blyth as above. The former appears to us to 
be the more probable supposition. 
58. Pernis tweeddalii. 
Pernis tweeddalei Hume, Stray Feathers, ix. pp. 446-8

59. Pernis cristatus. 
Pernis cristatus Cuv. Regne Anim, i. p. 335 (1829). 
Pernis ptilonorhynchus (Temm.); Sharpe, tom. cit. p. 347. 
Both these species, if they are distinct, occur throughout 
the Peninsula, but specimens in the plumage figured by 
Hume as P. tweeddalii are very rare and we have only come 
across two or three of them. Immature birds without crests 
are fairly common in the winter months. 
Pandionim. 
60. Pandion haliaetus. 
Pandion haliaetus (Linn.) ; Sharpe, tom. cit. p. 449. 
On the coast and in suitable localities as far as thirty miles 
inland the Osprey is fairly common throughout the Peninsula.
