chincnsis. Our peninsular species differs from the Chinese one in the following particulars. 

 It has a smaller bill, the secondaries are broadly margined with yellow on their external 

 webs, the innermost of these and the tertiaries having the outer web entirely yellow, 

 whilst in chinensis these are almost entirely black. The centre tail feathers in our bird 

 are black to their tip, being only faintly margined with yellow, whilst the Chinese one 

 has a broad yellow tip ; and the remaining rectrices have the black extending corres- 

 pondingly further than in chinensis ; the black ocular mark extends in our bird to the 

 nares, whilst in the Chinese specimens it only extends a little beyond the angle of the 

 mouth ; the band too is much narrower on the nape in the Indian bird ; the feathers of the 

 back have usually a greenish tinge, and the yellow throughout is less pure and bright 

 than in the Chinese bird ; and lastly the tail is considerably shorter. Swainson's 0. coronatus 

 from Java (as described) differs from our peninsular bird, and also from true chine7isis, in 

 its smaller size, shorter wings, tail, and tarsus, and in the narrowness of the black nuchal 

 band. Its bill appears to be somewhat larger than in ours, but shorter than in chinensis. 

 Wagler's description of O. hippocrepis, which he considers the same as chinensis auct., 

 corresponds with it in the yellow tips of the centre tail feathers, and with our peninsular 

 bird in having the black ocular band extending to the nares, and in other points. As how- 

 ever his specimens were obtained chiefly from Java and Sumatra, it is most probably 

 Swainson's coronatus, with which indeed it agrees in dimensions pretty nearly, as will be 

 seen in the accompanying table I give for the sake of comparison.
