Fig. 2. A throat-hackle of the Eaveu of Sikhiin (a) and of the 

 Raven of the Punjab (b). 



Coloration. Entirely black, glossed with steel-blue, purple, and 

 likic ; ihe throat-hackles long and conspicuous. 



Iris brown; bill and legs shining black (Hume Coll.). 



The following are the dimensions of the larger race found in 

 the Himalayas: length 28 inches; tail 11*5; wing up to 19-3; 

 tarsus 2*7 ; bill from gape 3*2. The smaller race from the plains 

 measures: length about 24; tail 9'5 ; wing 16 '3 to 17*4; tar- 

 sus 2'3 ; bill from gape 2-8. 



The Eaven of Tibet, Sikhiin, Nepal, and the higher portions of 

 the Himalayas is recognizably distinct from the Raven which is 

 found as a permanent resident in Sind, Eajputana, and the Punjab. 

 The Alpine race, a dweller in a cold bracing climate, has developed 

 into an immense bird somewhat larger than any I have been able 

 to pick out from a series of more than 50 Ravens from all parts
