42 COKVIDJE. 



This species is not a true Raven, but is a large form of C. levail- 

 lantii. It is larger in general appearance; but it is exceeded 

 in lengtb of wiug and tail by some specimens of the Malayan birds, 

 as will be seen by the above measuremeDts. I therefore consider it 

 only a race of that -widespread form which, under the titles of C. le- 

 vaillantii or C. macrorhi/mhn, is spread over the greater part of Asia.

Adult female. Black, with a very rich purple gloss, all the bases 

 to the feathers pure white ; wings rich purple, like the back, the edge 

 of the wing, the primary-coverts, and the outer aspect of the primaries 

 deep greenish black ; tail purplish black, shaded with steel-green on 

 the outer feather ; head all round greenish black, the feathers of the 

 thi-oat distinctly glossed with green and somewhat lanceolate, the 

 hinder neck somewhat greyish purple ; remainder of under surface 

 ashy black, with a slight purplish gloss ; bill and feet black. Total 

 length 21 inches, culmen 3-1, wing 13-4, tail 7'8, tarsus 2-1 5. 



Adult male. Similar to the adult female described, but decidedly 

 more grey, the feathers under certain lights having greyish margins 

 both on the upper and under surface. Total length 20 inches, 

 culmen 3-2, wing 13-3, tail 7'0, tarsus 2-15. 



Ohs. Professor Schlcgel refers this species to the neighbourhood of 

 Corone. vcdida, C. enca, and its aUies ; but in reality it is a strong- 

 billed representative of C. macrorJii/ncha, distinguishable from that 

 species by its long and peculiarly shaped bill and by the purplish, 

 not green, shade of the underparts. He also states that the Crows 

 of Kaioa Island are referable to this species. The birds collected 

 there by Mr. Wallace, however, belong to the race known as 

 C. orru.
