12 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 10/ 



Specimens examined. — Burma : Thayetmyo District : Thayetmyo 

 (i male), Pyalo (i male) ; Prome District: Shwedaung (i female) ; 

 Tharrawaddy District: Pinmezali Resthouse (i female) ; Insein Dis- 

 trict: Insein (i male) ; Rangoon Town District: Rangoon (2 males, 

 4 females). 



Remarks. — Bowdler Sharpe based his intermediimi upon two ex- 

 amples (one a juvenile) from Dilkhusha (a locality not shown on 

 modern maps, but situated on the Barak River in the Cachar District 

 of Assam) and an unknown number of specimens from Thayetmyo 

 (borrowed from Wardlaw Ramsay). The description is unsatisfac- 

 tory, and no type was designated, but the colored plate appears to have 

 been taken from one of Ramsay's southern birds ; certainly it is not like 

 the form from the hills north of the Surma Valley that I have called 

 chanielum. Whatever race is found at Dilkhusha cannot possibly be 

 identical with that of Thayetmyo, and I adjudge it best to make 

 Sharpe's name an absolute synonym of Hume's minus and thus to 

 remove it from all further consideration. 



14. PELLORNEUM RUFICEPS SUBOCHRACEUM Swinhoe 



Pellorncmn siibochraccum Swinhoe, Ann. Alag. Nat. Hist., ser. 4, vol. 7, Apr. 

 1871, p. 257 ("the Tenasserim provinces": type locality here restricted to 

 Moulmein, Amherst District, Tenasserim Division, Burma). 



Diagnosis. — Similar to P. r. minus, but distinguished by having 

 the brown of the upper parts paler and less olivaceous, more rufes- 

 cent ; the under parts washed with a more vivid buff. 



Range. — Burma (Salween, Thaton, Amherst, Tavoy Districts, and 

 mainland Mergui District). 



Specimens examined. — Burma: Salween District: Sinzwe Forest, 

 Yunzalin River (i male) ; Thaton or Amherst District: "Thaungyin 

 Valley" (3 females); Amherst District: "Hteekleethoo Choung" (i 

 female), Mepale (i male, 2 females), Kaukareik (i male), Lampha 

 (i female); Mergui District: Bokpyin (2 males). Ban Sadein (i 

 female). 



Remarks. — Although P. r. snbochraceiim is not a strongly marked 

 form, yet it seems to be readily separable in series; it is in some 

 respects transitional between minus and the following archipelagic 

 race.
