NOTES ON A NEW DUMETICOLA AND ON TRIBURA 



The average colour is reddish brown above, rather darker on 

 the head, but No. 6 is of a paler and more olive tone than the 

 others ; there is a fulvous supercilium ; cheeks and ear-coverts 

 mottled with brown and fulvous ; chin and throat white ; pale 

 rufous across upper breast ; abdomen white ; sides of breast 

 and flanks rufous brown ; vent and lower tail-coverts pale ru- 

 fous brown, in some tipped with dull white. In the generally 

 pale rufous colour of the lower tail-coverts it differs from the 

 allied species ; tibial plumage pale rufous brown externally, and 

 whitish on the inside of the leg ; tail reddish brown, and obso- 

 letely rayed ; bill brown, pale on lower mandible, save towards 

 the tip ; legs, feet, and claws, light brown. 



No. 1, Native Sikhim, June 1874; No. 2, Native Sikhim, 

 April 1874 ; No. 3, interior of Sikhim, May 1874 ; No. 4, 

 Sikhim, March 1872 ; No. 5, Lower Hills, Bhotan Dooars, 

 February 1874 ; No. 6, Bhotan Dooars, February 1874. The 

 form of the bill is exceedingly like that of D. affinis ; outer tail 

 feathers '84 short of end of tail ; lower tail-coverts of the same 

 length as the outer tail feathers. From tip of bill to back of 

 skull 1*22 inches. 



I cannot make out any generic difference between Tribura 

 and Dumeticola, and for convenience sake, it would be better to 

 term Tribura luteoventris, Dumeticola luleoventris in future. 



Dumeticola aflinis, (Hodgson.) 



Eight examples of Mr. Mandelli's examined : —

 mandible ; of No. 2, all shining black ; No. 3, the same ; No. 4, 

 the same ; No. 5, black, but pale at base of lower mandible ; No. 

 6, all black ; No. 7, very dark brown, and light coloured on 

 lower mandible, except towards tip; No. 8 the same. The 

 plumage of Nos. 1 to 5 is dark rich olive brown above, with a 

 rufous tinge, the general tone being much darker than that of
