new Saxicoline form {Rhodophila melanoleuca, Jerdoii). This is 

 not much unlike Pratincola ferrea of Hodgson in structure, but 

 in habit very different from the Pratincola, as it keeps to the 

 interior, and not to the tops, of the wild-rose bushes {Rosa 

 involucrata) so abundant in all that region. It is of a shining 

 black above, and pure white below. The young of Pratincola 

 leucura, in their speckled nestling plumage, were observed in 

 plenty ; whereas the species common about Calcutta, Pr. indica, 

 nobis, is certainly a migrant. Mr. Hodgson terms this species 

 Pr. saturatior, which expresses the reverse of its distinction in 

 colouring from P. ruhicola of Europe. From the latter, however, 

 I may remark, it differs much in its note. Dr. Jerdon also obtained 

 there the true Caprimulgus mahrattensis, Sykes (to which my C 

 arenarius from Scinde must be referred), a bird not previously 

 met with in Bengal. 



P. 36. Not only is Haliaetus leucogaster a noted robber of 

 the Osprey, but also H. fulviventer (v. macei) not unfrequently 

 does the same act. 



P. 55. Phylloscopus nitidus, nobis {Musicapa nitida ? Latham), 

 is as totally distinct as any species can be from the Motacilla 

 proregulus of Pallas. Why should Phyllobasileus (1851-2?) 

 take precedence of my Reguloides (1847 ?). 



I now refer to this group the following species : — 



1. R. pulchra [Abrornis pule her et abrochroa, Hodgson), S.E. 

 Himalaya. 



2. R. trochiloides (Acanthiza trochiloides, Sundevall ; Phyllo- 

 pneuste reguloides, nobis), N. India generally, also Burmah. 



3. R. viridipennis, nobis, Sikkim and Burmah. 



4. R. super ciliosa (Gmelin), {proregulus of Pallas). 



5. R. chloronotus (Hodgson), Himalaya and China. 



Ph. nitidus, nobis, belongs to my restricted genus Phylloscopus. 



N.B. Sylvia javanica, Horsf., is referred to Zoster ops in the 

 India House Catalogue {vide antea, pp. 66, 69). 



P. 83. I consider Aquila bifasciata to be a phase of plumage 

 of A. imperialis. A. fulvescens of India is distinct from A. 

 ncevioides of Africa, which is larger and more robust ; A. hastata 

 is also a good species. I presume that A. bellicosa of Africa is 

 identified with A. bonellii, and A. morphnoides of Australia with
