streaks, the female in full green plumage, like the first-men- 
tioned male. 
I have compared these Sibu birds with a large series from 
Sarawak (Wallace), Malacca (Wallacé), KE. Java (Wallace), 
and Tenasserim (Packman), and I find them all identical. 
The Philippine bird is duller and more bronzy, with a shghtly 
stronger bill, as pointed out by Count Salvadori; but the slight 
purplish violet shade mentioned by him is not a character, as 1t 
exists in Malaccan skins sometimes. The Philippine species 
is C. panayensis (Scop.), and measures 4°15 inches in the 
wing, which is about the size of C. chalybea. 
C. tyileri, from the Andamans and Nicobars, must be kept 
distinct: it is dull-coloured, like the Philippine species, but 
very much larger: wing 4°5 inches. Lord Walden considers 

it to be the same as continental examples of C. affinis (Ibis, ~~ 
1874, p. 145). I have four specimens before me from the 
Islands of the Bay of Bengal; and I cannot consider them 
quite the same as two Tenasserim birds, which, in tint of green 
and in size, agree with Malaccan ones. C. ¢ytleri, however, is 
not a very strongly marked species. [Cf. also Lord Walden’s 
recent observations (Ibis, 1871, p. 461).]| 
The following remarks apply to Lord Walden’s synopsis 
of the genus Calornis (Tr. Z. S. vi. pp. 79, 81), where the 
best review of the genus is to be found :— 
C. neglecta, Walden, l.c.. Hab. Celebes and Sula Islands. 
The single Celebean specimen (Meyer) in the Museum not 
being quite full-plumaged, I cannot speak with certainty as 
to its complete identity with the Sula-Island bird; but the 
shade of green seems darker in the latter. Lord Walden, 
however, who has had better series to examine than I have, 
says they are the same. The long tail (4°4 inches) will dis- 
tinguish this species from C. chalybea, which it approaches 
in colour ; it measures nearly an inch more than in the latter 
bird, whose tail does not seem to exceed 3°5 inches. 
Calornis obscura, Forst. A very dull green species, of 
which the Museum has a series of specimens from Batchian, 
Gilolo, and Morty, all collected by Mr. Wallace. 
Calornis crassirostris, Walden, I. c. p. 80. This species I
