found in the plains, whilst S. crinigera crinigera is essentially 

 a hill species. 



Two specimens collected by Col. Rippon on Popa Hill, 

 Mynigyan District, have black bills, longer tails, and traces 

 of a striped plumage ; these may possibly represent another 

 subspecies or S. c. crinigera. 



I have named this subspecies after Mr. J. Pemberton 

 Cook, who first drew my attention to the differences in 

 plumage. 



SUYA CRINIGERA YUNNANENSIS, Subsp. n. 



In the Natural History Museum there are seven examples 

 of this form from Yunnan, two collected by Dr. Anderson 

 in June and five by Col. Rippon in March and April. This 

 subspecies is most noticeable on account of its very dark 

 appearance, and can be easily separated from S. c. crinigera. 



Male in summer-plumage. Head very dark sooty-brown, 

 almost black, each feather with paler edges, producing a 

 slightly mottled appearance ; back dark brown, the feathers 

 also with light edges ; wings dark brown, outer edges of the 

 primaries light brown; tail light brown. Throat and breast 

 fulvous - white, the black bases of the feathers showing 

 through; under wing-coverts buff; thighs and under tail- 

 coverts darker. Bill (in dried skin) intensely black. 



Culmen 10 mm. ; wing 58 ; tail 103; tarsus 20. 



Female in summer -plumage. In general appearance very 

 similar to the male, but slightly paler, the feathers having 

 broader edges ; also the head is of the same colour as the 

 back. 



Wing 51 mm. ; tail 90 ; tarsus 20.

Obs. The winter-plumage is at present unknown. Three 

 skins (sex undetermined), collected by Col. Rippon in March 

 and April, are much lighter than those described, and may 

 be in a transitional stage, the whole upper plumage having 

 a striped appearance caused by the shafts of the feathers
