148 Mr. P, L. Sclater on an undescribed species of Hawk. 



is from this country, and the beautiful Accipiter castanilitis of 

 Prince Bonaparte* comes from the maritime portion of the 

 same EepubUc. The bird we are now about to describe is a 

 close ally of the latter species. It is an inhabitant of the in- 

 terior of New Granada, an adult example in the gallery of the 

 British Museum having been received with other birds from 

 Bogota in 1854. Dr. Kaup of Darmstadt, who has devoted 

 much attention to the Birds of Prey, attached to this specimen 

 some years ago the MS. title ' Micronisus collai'is' but never 

 published a description of it. I adopt Dr. Kaup's specific term 

 but prefer to place the bird in the genus Accipiter, to which it 

 appears quite sufficiently related. The front figure (Plate VI.) 

 is taken from the typical example. The younger bird in the 

 background is drawn from a specimen in Mr. J. H. Gurney's 

 collection, selected out of a large series of Bogotan birds in 1859, 

 and kindly submitted to my examination. To the same gentle- 

 man's liberality I am indebted for the plate illustrating this 

 species, from the pencil of Mr. AVolf. It may be characterized 

 as follows : — 



Accipiter collaris. (Plate VI.) 



Micronisus collaris, Kaup, in Mus. Brit. 

 Supra fusco-niger : subtus albus, vittis latis fusco-nigi-is regu- 

 lariter transfasciatus : gula immaculate alba : cauda fasciis 

 quinque, subtus albis supra cinereis apparent! bus : rostro 

 nigrOj cera et pedibus flavis, unguibus nigris. Long, tota 

 ]0'5, alse 6'75, caudse 5*0, tarsi 2"0. 

 Hab. in Nova Granada interiore. 

 Mus. Brit, et Joh. Henr. Gurney. 



An irregular white collar at the back of the head shows itself 

 on disturbing the feathers. The wings underneath are white, 

 distinctly and broadly banded with black. The tail-bands are 

 nearly obsolete on each outer rectrix. The wings reach to about 

 two inches from the end of the tail : the third primary is longest, 

 the second equals the fourth, and the first is slightly longer than 

 the fifth. 



There is no American species of Accipiter that this can easily 

 be confounded with, but it somewhat resembles A. minullus of 

 Southern Africa.
