POMATORHINUS EKYTHBOGENYS GRAVIVOX,* David. 



DavicVs Scimitar Babbler. 



1\ gravivox, David, Ann. Sci. Nat., xviii., art. v., p. 2 (1873), Hartert, Pal. 

 Vog., i., 638; Harington, B. N. H. S. J., xix., p. 115. 



Very similar to P. e. macclellandi, Jerdon, from Assam differs in having its 

 upper plumage of a more greenish tinge, and the stripes on the throat 

 black instead of grey ; the sides of the body and flanks a rich chestnut 

 instead of olive-brown. 



Distribution. — The Bhamo hills, Yunnan, Schensi, and Kansu China. 



Nesting. — I found this bird fairly plentiful in the Bhamo Hills, and 

 procured its nest, this is an untidy dome-shaped structure placed on the 

 ground, the eggs measuring 1'07 x '87 inches. 



POJMAXORINUS HYPOLEUCUS. 



The Giant Scimitar Babblers. 



These three nearly allied forms are giants amongst the Scimitar-Babblers 

 and almost constitute a genus by themselves. 



Their range at present is not satisfactorily known, but probably extends 

 from Assam down both sides of the Chin Hills ; and from Tenasserim 

 down the Malay Peninsula. 



Three closely allied forms are known. 



P. h. liypoleucus, Blyth. From Assam and Manipur and Arracan. P. k. 

 tickellii, Blyth., Tenasserim, P. h. lorayi, Sharpe, Perak Mountains. Malay 

 Peninsula. 



'"' A very nearly allied sub-species.

Hab. — Occurs in Szechuen and Tibet. 



PoMATOUHiNus (Drymocataphus) rubiginosus, Waldcn. 



Trichostoma rubiginosa, Walden, A.M.N.H. (4), xv., p. 402 (1875). 

 Drymocataphus rubiginosus, Sharpe, Cat. B. M., ii. v., p. 5600 : Gates, F.B.I. , i.. p. 

 145. 

 Pomatorhinus rubiginosus, Haring'ton, Bui., B.O.C., xxxiii., p. 46 (1913). 



'■ The only examples of this so-called species are two from Karennee, both in the 

 British Museum. These are quite young birds, and are very similar to young- 

 examples of Pomatorhinus imberbis, Salvadori, a species which 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, diiier from specimens of P. imberbis 

 of a similar ag"e in having" tae upper parts much browner and the breast and flanks 

 dull chestnut instead of rusty red." 



" The adult of P. rubiginosus still remains to be discovered." (Harington). 



On re-examining these two specimens and comparing them with the young of 

 P. erythrogenys, I find that they agree in colour with the only specimen of the 

 young of that species available, but both, the specimens of P. rubiginosus, Walden, 

 and the young bird of P. erathrogenys, difEer in the same way from the adults of 

 these t\%'-o species, which are so similar in coloration, in having a much more rufous 

 tinge to their upper and lower plumage, which I think must be caused by chemical 

 action. It is most improbable that there should be nearly allied undescribed sub- 

 species of Scimitar-Babbler in the Karennee Hills, from which locality there are 

 numerous specimens now available of P. imberbis. 



I therefore consider these two specimens to be merely the young P. e. imberbis, 

 Salvadori. 



As the name rubiginosus. Blyth, is a synonym of P. /. ferruginosus, Blyth. 

 Walden's name, therefore, could not stand in any case.
