238 Mr. Blythes Commentary 
with T. alaudarius } and Athene castanotus of Ceylon with A. 
radiatus . 
15. LlTHOFALCO iESALOX. 
“Peking, Amoy, and Foochow” (Swinhoe, P. Z. S. 1863, 
p. 260). In ‘ Ibis/ 1864, p. 418, Mr. Swinhoe records having- 
noticed a pair of Merlins at sea, on the voyage from Bombay to 
2 ij Galle ! (Were these satisfactorily identified ?) Capt. T. Hutton 
23 L remarks that the Merlin occurs at Kandahar (Journ. As. Soc. B. 
xvi. p. 775). 
17. Tinnunculus alaudarius. 
There is a Tenasserim (Siamese province) Kestrel to which 
attention should be directed— T. saturatus , Blyth (J. A. S. B. 
xxviii. p. 277). An adult female received from Ye is noticed in 
my ‘ Catalogue 3 of the Birds in the Calcutta Museum (No. 69) 
as " perhaps the female of a distinct race, remarkable for the 
great development of the black markings of its plumage.” A 
young female of the same race was subsequently obtained, in 
which the cap is fuscous, with scarcely an indication of rufous 
margining the feathers, the fuscous colour also predominating over 
the rufous upon the whole upper plumage; and on the tail the 
rufous bands are narrower than the black bands. An adult male 
Kestrel, from the vicinity of Moulmein (though rather deeper- 
coloured than usual), differed in no respect from the common T. 
alaudarius ; but it might well have been a stray individual of the 
latter, which is common in the adjacent Peguan province of the 
Indo-Chinese subregion; or perhaps, though less probably, the 
adult male of T. saturatus may prove to be less strongly distin¬ 
guished, as is indeed exemplified by T. japonicus (Faun. Japon. 
tab 1 & 1 b). T. saturatus is quite distinct from T. moluccensis 
(Hombr. et Jacq. 1 Voyage au Pole Sud/ Ois., tab. 1 & 2). 
19. Erythropus vespertinus*. 
The rufous plumage of the adult female of this species was 
unknown to Dr. Jerdon. In the f Annals of Natural History ; for 
* [It would he very desirable to ascertain whether examples of the so- 
called E. vespertinus from India are to be referred to the western form of 
Red-footed Falcon or to the eastern, with the light-coloured under surface 
to the wings, E. amurensis. Vide supra, p. 119. — Ed.]
