with the exception of the colouring of the tail and breast. The 

 tail is rufouSj hardly so vivid as in typical specimens of T.rufi- 

 collis, but much more vivid than in any specimen of T. atro- 

 gularis. The breast is a fine deep vandyke-brown, much 

 darker than in any specimen of T. rujicollis, and easily 

 distinguishable from that of T. atrogularis. 



It is apparently Dybowski^s T. hyemalis ; but I leave it for 

 Mr. Seebohm to pronounce on its merits as a hybrid or a 

 good species. Mr. Seebohm's collection contains a similar 

 specimen from Lake Baikal ; and I have also one shot in 

 Yarkund. 



Q7. TuRDUs ATROGULARiSj Tcmm. 



When I wrote concerning this species in a former paper 

 (Ibis, 1881, p. 53), I did not observe that I had before me a 

 specimen of an adult male in a melanistic form of plumage. 

 The feathers of the head and hinder part of the neck are 

 tinged with black ; the tail is much darker than in other spe- 

 cimens ; and the axillaries and under coverts are dull brown. 

 All other specimens that I have seen have the axillaries and 

 under wing-coverts dull rufous. 



70. Trocalopteron lineatum, Vigors. 



My Gilgit specimens of this Babbler are much paler 

 than those I have from Cashmere, which, again, are paler 

 than those sent me by Mandelli. The difference between 

 Gilgit and Simla forms, however, is greater than between 

 the Simla and Darjeeling forms. Specimens of Sibia capis- 

 trata from Murree and Sikkim show the same differences of 

 coloration. 



72. Pratincola indica, Blyth. 



PrATINCOLA MAURA, Pall. 



73. Pratincola robusta, Tristram. 



Dr. Scully has shown (Ibis, 1881, p. 441) that our large 

 Gilgit Bush-Chat is not Canon Tristram^s species ; but I can- 

 not allow that all the Chats of the P. indica (or maura) type 

 are referable to a single species. My collection contains 

 forty-eight adult specimens from different localities. These
