Mr. R. Swinhoe on Birds from Hakodadi. 331 
he has nothing to compare the latter with. Length 17f, 
wing 9f. 
He mentions having received a male Osprey from Kam- 
tchatka, giving its measurements 20i x 19|. This, from its 
large size, would appear to be the Pandion haliaetus (L.). 
He also adds, “ Hirundo, an example from Kamtchatka, 
agrees with Wilson's description of H. americana <$ , 7\ x 4f. 
(Baird's description in f Pacific R.R. Report/ 1858, is im¬ 
perfect.) Differs from H. gutturalis in having whole under¬ 
parts, except breast-collar, fine bright chestnut, but lighter 
than forehead and chin. No white, except on tail-feathers, 
which are also tinged with chestnut. N.B. H. gutturalis is 
sometimes tinged with light chestnut about the neck and 
under wing-plumes." This is Pallas's Siberian variety of 
Hirundo domestica ( = 11. rustica, L.), to which he (Zoograph. 
Rosso-Asiat. i. p. 228) gives no special name. Wilson's name 
is a synonym of H. horreorum , Barton ( = H. erythrogaster , 
Bodd.). 
Blakiston notes Cypselus pacificus, but sends no specimen; 
so I do not enter it under a number. Last time, he sent 
Acanthylis caudacuta under this name; but this time I 
think be is right. He says, Only one example. Length 
about 7 inches, wing 6|. Upper parts dull sooty black, ex¬ 
cept white rump. Underparts same, with white on chin and at 
end of its breast-feathers." 
127. Caprimulgus jotaka, T. & S. 
The wings and head of this species have come. 
128. Ceryle rudis. 
No specimen sent. “ Males and females do not differ ma¬ 
terially." This is the first occurrence of this bird so far 
north. I did not find it in China further north than the 
Yangtsze. 
He asks if I was right in identifying the two Shrikes 
he sent the last time, the one as Lanius bucephalus, the 
other as L. superciliosus. If so, his specimen sent in 1862 
was misnamed. I can vouch for mine being rightly de¬ 
termined.
