ORNITHOLOGY. 



not determine, however, that this species is identical with G. carun- 

 culatus (Gmelin), though such a conclusion has been adopted to some 

 extent by ornithologists. 



This species is larger than the preceding, with a similar longitudi- 

 nal stripe on the throat, but of greater extent. Under parts white, 

 which color extends upwards on the neck, leaving between its termi- 

 nation and that of the white stripe on the throat, a narrow, transverse 

 band of glossy black, with a blue lustre, which is the color of the 

 head and neck behind. Back, wing-coverts, and shorter quills brown, 

 with a greenish and bronzed lustre ; middle of the back and rump, 

 greenish-blue. Sides (under the wings), and large space on the flanks 

 and tibise, deep black, with a bluish lustre ; under tail-coverts black. 

 Feet light colored.. Total length of prepared specimen, about thirtj^- 

 one inches; wing, eleven and a half inches; tail, four and a half 

 inches. This is apparently a more mature plumage than the succeed- 

 ing. 



Younger ? Under parts from the base of the lower mandible white. 

 Upper parts like the preceding, but tinged with brown on the head 

 and neck, and much less glossy. 



We find no notes, relating to either this bird or the preceding, placed 

 on record by either of the naturalists of the Expedition, and like the 

 preceding species, the present has not been figured in the plumages 

 which we regard as most mature, and we have doubts whether the 

 figures of Reichenbach, cited above, are really of this species. The 

 description, however, of Garho BougainviUii, as above, seems to be ap- 

 plicable to our present bird, and the name synonymous with Pliala- 

 crocorax atriceps, as given at the head of this article. 



This species is arranged by the Prince Bonaparte, as belonging to 

 his Genus Vrile, in his Monograph of the Plicdacrocoracidae, in Con- 

 spectus Avium, II, p. 176. Specimens in good preservation are in the 

 collection of the Expedition.
