Eornean specimens exhibit a distinct blackish shade at the base of 

 the outer tail-fcathors, and in this respect resemble Sumatran skins. 

 One of the chief differences, however, between C. suavis of Borneo 

 and C. tricolor consists in the very dark colour of the female bird ; 

 and I should consider this of more direct importance were it not 

 evident that a p^reater darkness of coloration in the female of C. tricolor 

 is gradually evident as the Burmese countries are reached, and is also 

 seen in examples from, the Malay Peninsula. In Java, tho female 

 birds are apparently so dark- coloured as almost to resemble the males ; 

 and hence we have three races ; — 



1. C. tricolor from India, extending through tho Burmese 

 countries down the Malayan Peninsula. 



2. C. tricolor from Java, with a black base to the outer tail- 

 feathers, and the female like the male but with a shorter tail. 



3. C. suavis, with the sexes as in the last, but with very little 

 or no black base to the outer tail-feather. 



The chief character of the Bornean bird called by Dr. Sclater C. 

 svai'is was the pure white outer tail-feather ; but this is a character 

 which Latham gives to his " Long-tailed Thrush " from Pulo Condore, 

 an island lying off tlie coast of Cochin China ; for neither in descrip- 

 tion or figure is any thing said about a black base to the outer tail- 

 feather. Until specimens from Pulo Condore are examined and 

 found to be absolutely tho same as C. suavis of Borneo, I think it 

 better to drop Latham's name, because it is almost certain that 

 Siamese and Pulo-Condore skins will bo the ordinary C. tricolor, 

 and in that case the description and figure given by Latham would 

 prove to be inaccurate. It would then be inconvenient to allow the 

 name of macrurus (with its white outer tail-feather) to stand for 

 the common Shama, when there is a Bornean race or subspecies 

 which possesses the white tail-feather, but yet was not the bird ex- 

 amined by Latham.
