Assensole, India, lOth July, 1872. 

 Dear Sir, — I wish to make a few remarks upon Mr. Hume's 

 six new species described in ' The Ibis ' for April 1872, p. 107. 



1. Chrysomitris thibetana. — Is a true Siskin ; but 1 am 

 not sure of its distinctness from C. spinus $ . I think it 

 would have been better if Mr. Hume had reserved this bird till 

 he had an opportunity of comparing it with female specimens of 

 C. spinvLS. When I was at Simla, we had nothing to compare 

 it with but the descriptions of Macgillivray and Yarrell. 



C spinoides is not a Siskin, but a Greenfinch allied to 

 C. chloris. Like the latter bird, it has no regular song; but 

 its call-notes are very similar to those of its ally. In Cashmere I 

 did not observe C. spinoides after passing the first (or Pir-Punjal) 

 snowy range of the Himalayas. 



2. DuMETicoLA CYANOCARPA. — We certainly made a mistake 

 iu thinking that a Dumeticola could have any blue about it. 

 Mr. Hume's bird belongs to some other genus, and is much 

 closer to Brachjjiteryx than to Dumeticola. To the best of my 

 recollection I did not agree to this bird being classed as a 

 Dumeticola. 



The Dumeticola I procured in Cashmere was not D. affinis, 

 but a species an inch longer and with a much longer bill. It 

 has been described in the ' Journal of the Asiatic Society,' 

 part ii. no. 1, 1872, p. 77, as Dumeticola major. When I mis- 

 named this bird " D. affinis," I had not seen Mr. Hodgson's 

 drawing of that species. By " i). affinis" Mr. Hume refers to 

 my birds ; for neither of us had then seen the true D. affinis.
