age character. As a matter of fact, the series more closely resembles 

 a specimen of S. d. mmidelUi from Assam than it does S. d. genestieri. 

 It is not quite so biiffy on the throat and jugulum; the sides of neck 

 are unstreaked, or nearly so; the bill is smaller; the back and tail 

 are darker, more olive without so much of a reddish cast. 



104. STACHYRIDOPSIS RUFICEPS BHAMOENSIS Harington 



Stachyridopsis ritficeps bhamoetisis Harington, Ann. and Mag. Nat. Hist., 

 ser. 8, vol. 2, 1908, p. 245 (Bhamo, Burma). 



One male, Linchia, March 12. 



With only one specimen of jS. r. ruficeps from Annam — possibly 

 not the same as the Indian bird — it is hard to say exactly how they 

 differ. The Annam bird is considerably smaller than the present 

 specimen, more grayish on the back, and much lighter below. 

 /Stachyridopsis praecognitus (Swinhoe) is only a form of S. r. 

 ruflceps with a somewhat smaller bill, more restricted crown patch, 

 the back citrine not grayish or brownish, the lower parts more 

 yellowish.

Five adult males, two immature males, and three females, Li- 

 kiang Mountains. 10,000-12,000 feet, June-July. 



The adult males in this series are much darker below than two 

 males in the National Museum from Sikkim {Heteroxenicus cru- 

 ralis), especially on the breast and belly. In the Sikkim specimens 

 the breast and belly are neutral gray, sparingly streaked and tinged 

 with indigo, giving a bluish-gray cast. In certain particulars the 

 Likiang specimens do not agree with Stuart Baker's -" description. 



The concealed part of the wings and tail are not " dark brown " 

 but blackish or in the case of the tail, bluish. , It may well be that 

 they do not belong to the present species at all, but they agree better 

 with it than they do with any other form attributed to China. 



A specimen (296614) marked as a male is exacly like the adult 

 female, except it has a silky-white superciliary. A still younger 

 bird of the same sex in spotted plumage lacks the white superciliary. 



A female taken in June (297038) is lighter on the back, the fore- 

 head, and lores, and has a slightly smaller bill than the others in 

 the series and may not belong to this species at all, but I do not 

 loiow at present Avhere else to place it.
