into China, and down the Malayan peninsula, all the speci- 

 mens from Northern India being rather paler in colour, espe- 

 cially as females. 



Great variation in size exists, and this alone would not 

 serve to separate species of this genus : thus the tarsus varies 

 from rOo to 1*2 inch, being, however, generally smaller in 

 the hen birds. A Burmese female has it 1-15 inch in length. 

 The wing varies from 3*75 to 4 inches in the male, and from 

 3-65 to 38 in the female, the example from Burmah measur- 

 ing only 3 '35 in the wdng, and 3 inches in the tail. 



I am not disposed to separate the Malaccan species (usually, 

 though erroneously, called C. mindanensis ; cf. Walden, Tr. Z. 

 S. ix. p. 194) from C. saularis. The amount of white on 

 the third pair of rectrices is a character which must be re- 

 ceived with a great deal of caution, as it increases with age. 

 This is certainly the case with C. saularis, and, I doubt not, 

 w ith the allied species also ; and I have examined Malaccan 

 examples which have the same tail-markings as Indian birds. 

 Then, again, with regard to the dark coloration of the Ma- 

 laccan females, this is certainly noteworthy to a certain extent ; 

 but a Madras female in the Museum is quite as dark : the 

 birds from Northern India and Burmah seem paler. 



Of the Andaman species I am only able to judge by a single 

 female in the Museum ; and this bird is apparently different 

 on account of its rufescent flanks. Mr. Hume separates the 

 bird from this locality as C. andamanensis ; and in this he is 

 probably right. 



The Javan C. amoenus is distinguished by its grey under 

 sm'face in the female, the male being entirely blackish below. 

 It is represented in the Museum by specimens from W. Java 

 {Wallace), Bali.(fF«//ace), Labuan {Low), and Banjermassing 

 (Motley) . The Bali bird is glossy black on the under surface, 

 and has no admixture of grey like the Javan and Bornean skins. 



Lastly, Mr. Everett's Sibu skin remains ; and its specific 

 characters may be shortly summed up as follows : — Similis 

 C. saulari, sed tectricibus alarum inferioribus nigris, vix albo 

 anguste limbatis distinguendus. Long. tot. 8*6, alse 4-05 

 caudse 3'8, tarsi r25.
