ORNITHOLOGY. 



characters, or even in concluding that this bird is certainly different 

 from the last. The specimens are, however, apparently constantly 

 larger. 



To this bird, in immature plumage, Gmelin's name, cited above, ap- 

 pears to be applicable. The present specimens are from New Zealand. 



Like the preceding, the present bird is included by the Prince Bona- 

 parte in his recent Monograph, in the Genus Hypoleucus, Reichenbach. 

 He regards this species, and not the preceding, as Carho hypoleucus, 

 Brandt. We have the misfortune of not coinciding in manner and 

 form as the case stands, but we are not without a suspicion that both 

 are correct, the difference being in names, or perhaps nominal species 

 only.

Specimens in the collection of the Expedition are stated to have 

 been killed "at Manua Bay, New Zealand, in the month of March, 

 where they frequent the fresh-water or brackish creeks." This note, 

 by Mr. Peale, is the only reference to this interesting little species, 

 that we find in the journals of the naturalists of the Expedition. 



This bird is regarded by the Prince Bonaparte, in his recent Mono- 

 graph (Consp. Av. II, p. 178), as not the true Carho sulcirostris, 

 Brandt, and he accordingly proposes a new name for it, as above. We 

 continue it, however, as given by Mr. Gould, in Birds of Australia, 



* " Head, neck, and body, black, with an olive-green metallic gloss; wings and tail 

 black ; shafts black ; scapulars and wing-coverts purplish-gray, each feather edged with 

 black ; secondaries having their webs waved, somewhat like the Darters (Plotus) ; bill 

 bluish horn-color ; the upper mandible brownish ; eyelids and gular pouch purple ; irides 

 green. 



" Total length, twenty-four inches ; wing, from the carpal joint, ten and three-tenths 

 inches ; tail, five and three-tenths inches ; the outer feathers, three and eight-tenths 

 inches ; bill, one and eight-tenths inches ; to the corners of the mouth, two and six- 

 teaths inches; tarsi, one and seven-tenths inches; outer toe, three inches; nail, three- 

 tenths of an inch; hind toe, one and two-tenths inches ; nail, three-tenths of an inch."
