LUTEOVENTRIS, Hodgson, & DUMETICOLA AFFINIS, Hodgson. 285 



en inside of leg ; bill brown, but pale towards base of lower 

 mandible ; legs, feet, and claws light brown. 



The tail is much graduated, the outer tail feathers being '65 

 shorter than the central ones. 



From tip of bill to back of skull measures 125 inches. The 

 bill is stronger, longer, and deeper than in Tribura luteoventris. 

 Legs and feet of very similar character. 



The form of the wing is that of Dumeticola ; the 1st or small 

 primary is about '70 in length, the 2nd is *3 short of tip of 

 wing, the 3rd '08 from tip, the 4th "05, the 5th is the longest, 

 the 6th is intermediate in length between 3rd and 4th, and 

 from this they gradually diminish by about twentieths of inches; 

 the 11th is equal in length to the 2nd. 



From Tribura luteoventris it is easily distinguished by the 

 much larger and stronger bill ; also by the grey breast, and be- 

 ing subject to spots on the throat like D. major, Brooks, and 

 D. affinis, Hodgson. 



From D. major it is at once distinguished by its very rufous 

 tone of plumage and stouter bill. 



From D. ajjinis it k distinguished by its larger size, longer 

 tail, and very rufous tone of plumage. 



I should have remarked that the breast of No. 1 is of a 

 light brownish grey, while that of No. 2 is ash grey. 

 By the very similar form of bill, and tha upper surface of 

 each bird's plumage being of the very same tone of colour, 

 it is evident that they belong to the same species. 



No. 1 is from Native Sikhim, November 1873 ; and No. 2 is 

 from Native Sikhim, April 1874. 



Tribura luteoventris, {Hodgson) 



I have examined six of Mandelli's examples of this species.
