and contained two young birds, in one instance three. The 

 two long centre tail-feathers are often much worn, making 

 it difficult to obtain good specimens. 



I greatly doubt the fact of Mr. Treacher's specimen of 

 C. minor having really come from Labuan, and think there 

 must have been some mistake in the label. The species is 

 such a thorough mountaineer, and would be so utterly out 

 of place in a barren locality like Labuan, that I fancy it 

 must have really come from the Lawas district.]

Cissa jefferyi, Sharpe, Ibis, 1888, p. 383. 



When a series of this species is laid oiit side by side with 

 a similar series of C. minor, a great difference is noticeable at 

 once in the green colour of the bird, which is very decided, 

 and no yellow of any kind appears on the crown. Sometimes 

 a little bright blue can be seen in the plumage of the back, 

 but never appears on the uuderparts. Independently of the 

 striking differences in the wings and tail-feathers, pointed out 

 by me in my original description, C. jefferyi, as seen in a row 

 of specimens, can at once be distinguished from C. minor 

 by the much narrower tips to the tail-feathers, and these 

 pale ends are distinctly greenish white. 



The males of C. jefferyi have the wing 5*25-5"5 inches, 

 and the females 5'2-5'4. A young bird has a blackish bill, 

 the colour is more dingy, and there is no subterminal black 

 band on the tail at all. 



[Bill and feet deep lake-red, much darker than in C minor. 

 Iris white, with a faint pink tinge round the pupil. In the 

 young birds the bill is duller in colour, blackish towards the 

 base. 



I first met with this beautiful bird at 8000 feet, and I 

 could tell at once, from its note, that it was a different 

 species from C. minor, and concluded that it must be a high- 

 land representative of the latter; but when camping at 3000 

 feet this species w^as met with again, so that it is evidently 

 the thick forest which divides the two species. While 

 C. minor inhabits the more open and cultivated districts, 

 C. jefferyi, even at its lowest altitude, never quits the true
