" Iris brown ; bill and feet black ; stomach, insects. Island 

 of Negros." 



The single specimen sent has the under wing-coverts entirely 

 black as in C. pluto (Temm.). This at once distinguishes the 

 Negros bird from the Dhayals of India, Ceylon, Burma, Ma- 

 layan peninsula, and Java. Unfortunately the Negros example 

 possesses only eight perfect rectrices ; but these are entirely black. 

 The stump of a ninth, however, is present ; and it, as far as it 

 remains, is also black. It may be inferred, therefore, that at 

 least ten of the rectrices of the Negros Copsychus are black, and 

 it may be possible that all the twelve are black. Without other 

 Philippine examples to compare with, it cannot be decided 

 whether this Negros individual agrees with the Mindanao species. 

 I3ut for the present it is proposed to regard the two as identical. 



The Malayan and Javan Copsychus hitherto referred to Tardus 

 mindane)isis, Gm., differs from this Negros individual in having 

 six white outer rectrices, and in having the under wing-coverts 

 white centred with black. These characteristics have been 

 verified by an examination of a considerable series of Malayan- 

 peninsular and Javan specimens. As is well known, Indian, 

 Cingalese, and Burmese examples have the under wing-coverts 

 pure white, and possess eight white rectrices. 



The oldest title for the Malayan and Javan Copsychus ap- 

 pears to be Lanius musicus, Raffles, Tr. Linn, Soc. xiii. p. 307 

 (1822), given to the Sumatran species, which in all probability 

 will be found to agree with the Malayan and Javan. 



In many individuals of C. saularis the fourth pair of rectrices, 

 and in C. musicus the third pair, are more or less brown or black.
