284- BIRDS OF TENASSERIM. 



the other points which I noted, the greater intensity of the 

 rufous coloring of the nape, and the more olivaceous tint of the 

 crown, can be insisted on as invariably constant. The more so 

 that one race, of what I must consider leucogaster for the present, 

 from the pine forests of the Sal ween, while exhibiting the 

 ferruginous on the sides of the breast and body, has a bright 

 ferruginous nuchal collar, as bright as in the brightest olivaceus ; 

 while some specimens of olivaceus that I have obtained do not 

 exhibit this rufous nuchal collar at all conspicuously. The 

 point of distinction is, that in one the ferruginous runs down the 

 sides of the breast and body ; in the other it does not. 



403 ter. — Pomatorhinus nuchalis, Tweed. A. and 

 M. N. H., December 1877, 535. 



The following is Lord Tweeddale's original description of 

 this new species or supposed species. If valid, it certainly 

 occurs in Karennee and the Karen Hills, as this is expressly 

 set forth by Lord Tweeddale ; and, judging from the remarks 

 I recorded in the last paragraph, it seems not improbable that 

 some of the specimens included by me under leucogaster would 

 be claimed for nuchalis by its describer. Having no specimens 

 with me here in the wilds of Rajpootana, I can say nothing 

 further about the species. 



" Pomatorhinus nuchalis, S.P. nov. ; Pomatorhinus leucogaster, 

 Gould apud Walden, B. Burma, No. 351. 



" Differs from P. olivaceus, Blyth, ex-Meetan and Mooleyit 

 (Tenasserim) by the ferruginous of the sides of the neck extending 

 down the flanks, and from P. schisticeps, Hodgs.=P. leucogaster, 

 Gould., by its smaller dimensions, and the absence of pure white 

 central streaks on the lateral ferruginous pectoral feathers. 



" This is the race that inhabits Thayetmyo, the Yoma and 

 Karen Hills, and Karennee. In examples from all these loca- 

 lities the nape is tinged with rufous ; but in Karennee indi- 

 viduals the rufous forms a distinct broad demi-collar. 



u This would appear to be the race identified by Mr. Hume 

 (S. F., Ill, p. 121) as P. schisticeps, Hodgs., a species which 

 cannot be separated from P. leucogaster, Gould., both described 

 from the Himalayas, the stated dimensions of P. leucogaster 

 scarcely differing from the actual dimensions of the type speci- 

 mens of P. schisticeps in the British Museum." 



I note that the birds I identified as schisticeps from Thayet- 

 myo were schisticeps, pur et simple, the larger race, and abso- 

 lutely identical with Sikhim examples. 



I distinctly say, he. cit., that specimens received from further 

 east in Northern Tenasserim are (t smaller birds with shorter 

 bills, a much less cenereous tinge upon the forehead and
