TETEAONID^. 



quills aud the outer half of the wing-coverts pure white ; middle of 

 the hreast and belly usually buff, more or less mixed with white 

 feathers ; tail as above, but the middle pair of feathers are black, 

 irregularly barred with rufous. 



Adult male [autumn plumage]. Throat and chest light brick or 

 pale chestnut colour, usually with finely mottled black cross-bars ; 

 the new feathers on the upper parts black with narrow irregular 

 rufous bars, in fact very similar to those of the summer plumage, 

 but the black greatly predominates and the tips are not so conspi- 

 cuously edged with white and rufous. 



Adult female [autumn plumage]. Feathers of the chin, throat, 

 and chest similar in colour to those of the male ; but, as a rule, 

 largely intermixed with summer plumage ; upper parts black, with 

 narrow bars of rufous buff. 



Adult male. Total length 15-5 inches, wing 8-1, tail 4-8, tarsus 

 1-4. 



Adult female. Total length 15 inches, wing 7"8, tail 4-3, tarsus 

 1-35. 



Immattire specimens are mottled and sometimes blotched with 

 black along the shafts of the primaries. 



Young birds resemble the female in breeding-plumage, but the 

 markings on the upper parts are usually more concentric, and most 

 of the feathers of the mantle, scapulars, and wing-coverts have a 

 white spot at the extremity ; the primaries are pale brownish grey, 

 mottled along the outer web and round the tips with buff; chin, 

 hroat, belly, thighs, and under tail-covcrts pale buff.
