Dr. W. L. Abbott collected one female, Bok Pyin, Tenasserim, 

 February 14, 1900 (type of pellogyna); one male and three females 

 Mergui Archipelago (Domel Island, February 24, 27, 1900; St. Luke 

 Island, January 21, 1900; the last is an immature female and the type 

 of lamprogyna). He gives the soft parts as: Iris dark brown; bill 

 black; feet pale fleshy. 



This is a slightly darker and smaller form than the Malay Penmsula 

 race. With it I would place the specimens from southern Tenasserim 

 and the Mergui Archipelago. 



In the present series there are a number of immature specimens, 

 the immature in the spotted plumage being white on the breast and 

 belty but becoming red at the next molt, not so deep as in the adult, 

 however, and the females never so deep as the males. At successive 

 molts the breast becomes darker until the fully adult plumage has 

 been assumed. The rusty edging on the wing persists after an appar- 

 ently adult plumage has been assumed and seems to be retamed in the 

 female, even in the adult. Therefore the female may vary from a 

 very light plumsige on the breast and belly in birds m the first winter 

 plumage to quite red on these parts in older birds. The reason for 

 mentioning these changes is that a number of nominal races have been 

 separated by Dr. Oberholser. 



The type of pellogyna, Bok Pyin, Tenasserim, is a female, whitish 

 on the belly and rusty on the chest. The tA'^pe of lamprogyna, St. 

 Luke Island, Mergui Archipelago, is also a female, whitish on the 

 breast and belly with less rusty on the chest. In the series of females 

 of interposita collected by Dr. Smith, the specimens vary from a 

 bird that almost matches the type of lamprogyna below to one that 

 almost matches the type of abbotti on the lower parts, and I believe 

 these races are founded upon individual age characters and are not
