 slaty horn, cere and gonys yellowish green; feet dull yellow.

These birds are both immature, as is shown by the pale 

 edgings to the feathers of the upper surface, which is dark 

 brown, with a greyish tinge, the head much darker. Three 

 rather broad clearly defined dark bars on the tail and a dark 

 tip. Throat white, with a somewhat broad dark median 

 streak. Croj)-region with broad longitudinal stripes of dark 

 brown. Rest of the under surface broadly barred with reddish 

 brown, the bars more marked on the Hanks. Thighs 

 regularly barred with white and reddish brown. Under tail- 

 coverts white or slightly flecked with reddish brown. Fourth 

 primary longest, third nearly equal to it, fifth rather shorter. 

 Wing 165, 166 mm. 



There is little doubt that these two specimens represent 

 the Himalayan A. affinis hi winter quarter.s. Specimens 

 precisely agreeing with them except in size have been shot 

 in considerable numbers on small islands in the Straits of 

 Malacca, in company, however, with adult birds Avith little 

 or no barring on the under surface, that can with difficulty 

 be separated from the true Sundaic A. viryatus.
