Drymocataphus rubiginosus Sharpe, Cat. Birds Brit. Mus. 

 vii. p. 560 (1883) ; Oates, Faun. Brit. Ind. i. p. 145 (1889). 



The only examples of this so-called species are two 

 from Karennee, both in the British Museum. Both are 

 quite young birds, and very similar to young examples of 

 Pomatorhinus imberbis Salvadori, a species which was also 

 first described from Karennee, and of which there are now 

 numerous specimens in the British Museum from the Shan 

 States, Burma. 



The immature types of P. rubiginosus differ from speci- 

 mens of P. imberbis of a similar age in having the upperparts 

 much browner and the breast and flanks dull chestnut 

 instead of rusty-red. 



I am indebted to Dr. R. Gestro, of Genoa, who has most 

 kindly forwarded the type-specimen of P. imberbis Salvadori, 

 to the British Museum for comparison with P. rubiginosus 

 (Walden) . 



The adult of P. rubiginosus still remains to be discovered. 



Pyctorhis altirostris griseigularis Hume. 



Pyctorhis aliirostris griseigularis Hume, Stray Feathers, 

 v. p. 116 (1877). 



I find that Hume's species from Assam, and the Butan 

 Doars, is quite distinct from Jerdom's P. altirostris, from 

 Burma. There are now several specimens of each in the 

 British Museum, and the differences are quite apparent.

Mr. Erwin Stresemann made the following remarks on 

 the British House-Sparrow : —
