BIRDS OF TENASSERIM. 267 



pillns it is confined to the throat or nearly so, and is only dark 

 shafting to the feathers. 



Third, in tho very conspicuous yellow supercilium of rubri- 

 capillus almost obsolete in gularis. 



Fourth, in the much deeper red of the crown of gularis, and 

 the strong rufescent tinge on its back and wings, which is almost 

 wanting in rubricapillus . 



Fifth, in the deeper olive green of the sides of the head, neck 

 and body in rubricapillus. 



Now, if you examine specimens beginning at the extreme 

 north of Tenasserim above Kyouknyat, you find these and 

 others from Dargwin, Pahpoon, Sal ween District, 100 miles 

 north of Moulmein, Kaukaryit on the Houngthraw River, Moul- 

 mein, Yea-boo on the Attaran, Amherst, Lemyne, Meetan, 

 Meeta Myo, Tavoy, Shymootee, south of Tavoy and Thyet- 

 choung, 20 miles south of Tavoy, all true rubricapillus, but at 

 Mergui, and every locality in Tenasserim south of this, you 

 meet with gularis, or rather in the case of nine specimens out of 

 ten, birds much nearer to gularis than to rubricapillus. 



Some specimens, as already remarked, are absolutely identical, 

 but the majority are to a certain extent intermediate ; the stria- 

 tions of the throat extend on to the breast, and are much 

 stronger than in rubricapillus, but are yet not quite so strong as 

 in most gularis ; the size is larger, but does not average 

 quite that of gularis ; the coloration is deeper everywhere than 

 in rubricapillus, but yet not so deep as in what I consider typi- 

 cal gularis; but the yellow supercilium is more strongly deve- 

 loped as a rule than in either species. Unfortunately, owing to 

 local administrative difficulties, we have been unable to explore 

 the country intervening between Thayetchoung and Mergui, a 

 breadth of about 110 miles, and we are unable at present to say 

 whether, in this intervening tract, the two forms gradually 

 grade off one into the other, or whether, as is most probable, they 

 divide abruptly somewhere between Mergui and Tavoy. I 

 say more probably for this reason that a vast number of the 

 Malayan forms do suddenly cease to appear somewhere between 

 Tavoy and Mergui.

(TongJioo, Earns.) Pahpoon ; Yea-boo. 



Sparingly distributed, where high grass occurs, at any rate 

 in the northern and central portions of the province. 



[In the dense kine grass at Pahpoon this species was not rare, 

 but very difficult to obtain, owing to the grass being so thick 

 that it was impossible to see more than a foot or two, so that 

 when one did see the bird it was too close to fire, and on trying
