COPSYCHUS MUSICUS. 



Copsychus musicus (Raffl.), Tweedd. i.e. p. 309. 



The Marquis of Tweeddale is no doubt right in adding C. 

 problematicus of Sharpe (Ibis, 1876, p. 36) to this species, 

 the latter gentleman having evidently overlooked Lord Tweed- 

 dale's previous remarks on this subject. Mr. Buxton's pre- 

 sent collection contains a very large series, including the young 

 birds from the nestling stage upwards, as well as several adult 

 individuals of both sexes. This series, which is now in the 

 British Museum, will prove useful to anybody engaged in 

 working out this puzzling genus. I must mention also that 

 there are two birds in the series which seem referable to C. 

 amosnus of Horsfield, but are not so entirely black underneath 

 as adult individuals of that species. The question requires a 

 longer period of study than I am able to give during my 

 hurried visits to London ; but I must confess myself rather 

 puzzled by the two specimens in question, which seem to 

 indicate either a complete gradation from C. musicus to C. 

 ammnus, or else hybrids between the two species.
