BIRDS OF TENASSERIM. 311 



Legs and feet are reddish brown, darker in some, paler in 

 others ; bill almost black ; irides varying from burnt sienna 

 brown to dark cinnabar red. 



The cap is grey brown ; each feather margined rather paler, 

 and here and there a little tinged with olive green. 



The entire back, scapulars and rump hair brown ; the feathers 

 so broadly fringed with olive green that little else is visible ; 

 wings hair brown ; the quills broadly margined on the outer 

 webs with a yellower shade of the color of the back ; the 

 coverts margined and more or less overlaid with the same color ; 

 the tail feathers brown, more or less overlaid on the outer webs 

 with the color of the back, and more or less strongly margined 

 on the same with the yellowish olive green of the wings ; lores 

 dusky brown ; cheeks and ear-coverts grey brown ; the feathers 

 with conspicuous paler shaft stripes ; chin and throat albescent, 

 shaded with pale grey brown; breast and abdomen grey bro,vn, 

 a little pencilled and streaked with pale yellow, the yellow 

 having a faint ochraceous tinge ; sides and flanks darker and 

 browner ; lower tail-coverts decidedly pale ochraceous ; wing- 

 lining and axillaries very pale, somewhat ochraceous yellow ; 

 edge of the wing often yellower or greener ; internal margins of 

 quills on lower surface white, tinged creamy or pale buffy. 



To give a better idea of the average difference in size be- 

 tween this species and bmnneus, and between the two sexes of 

 each species, I give the exact dimensions of wings, and of bills 

 from forehead to point, of a number of specimens of each sex : — 



Therefore, although dimensions alone will not necessarily 

 suffice to separate specimens of the two species, or to separate 

 the males from the females in either species, yet, as a body, speci- 

 mens of plumosus average larger than brunneus, and the males, 

 in both species, average larger than their respective females.
