10 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I07 



phia, vol. 98, 1946, pp. 114-115). It is highly noteworthy that a race 

 quite distinct from shanense is found in the Siamese province of 

 Chiang Rai, less than 30 miles distant from Mong Len, one of the 

 localities for this new form. 



10. PELLORNEUM RUFICEPS HILARUM, new subspecies 



Type. — M.C.Z, No. 265793, adult female, collected at Kyundaw 

 (lat. 2i°oi' N., long. 94°35' E.), Pakokku District, Magwe Divi- 

 sion, Burma, on January 28, 1938, by Gerd Heinrich (original num- 

 ber 1274). 



Diagnosis. — The feathers of the uppermost back have the dark 

 brown centers even more obsolescent than is the case with P. r. 

 shanense. 



This race furthermore has the rufous of the front, crown, and 

 nape paler and slightly more grayish than in shanense (near to the 

 color of these parts in chamelum) ; the remaining upper parts grayish 

 olivaceous brown (but little browner than are these parts in punc- 

 tatum) ; the ground color of the under parts pale buff (slightly paler 

 than in shanense, with which it agrees, however, in the breadth and 

 abundance of the dark streaks on the breast and sides of the 

 abdomen). 



Range. — Central Burma (Mandalay, Meiktila, Pakokku, Lower 

 Chindwin Districts, and southern part of Upper Chindwin District). 



Specimens examined. — Burma: Mandalay District: Maymyo (i 

 male, i female) ; Meiktila District: "Kalaw" (i unsexed) ; Pakokku 

 District: Kyundaw (i female), Dudaw Taung (i male, i female); 

 Lower Chindwin District: Taungbauk (i male); Upper Chindwin 

 District: Mingin (i male, i female). 



Remarks. — So far as one may judge from a single example, the 

 bird collected at "Kalaw" belongs with this race. Kalaw lies just at 

 the western edge of the Shan Plateau, above the plains of Meiktila, 

 and one would hardly expect the population of the plateau to be out- 

 wardly identical with that of the lowland Dry Zone. Since the speci- 

 men has by no means as full data as one could wish, I have assumed 

 that the locality is only roughly correct, and that the bird was collected 

 somewhere near, but west of and below, Kalaw, and thus in the Meik- 

 tila District. 



11. PELLORNEUM RUFICEPS VICTORIAE, new subspecies 



Type. — A.M.N.H. No. 306134, adult male, collected on Mount 

 Victoria (lat. 21 "15' N., long. 93° 5 5' E.), Kanpetlet District,
