HARELDA, Leach. 
" Harelda, Leach, 1816," Gray. Type Anas glacialis, L. 
Clangula, Fleming, Philos. Zool. 1822. Same type. 
Pugonetta, Kaup, Europ. Tliierw. 1829. 
Ch.— Bill shorter than the head and tarsus, tapering laterally to the end ; the nail very broad, occupying the entire tip. 
Lateral profile of lower edge of upper mandible straight to near the end, then rising suddenly tt> the prominent decurved nail. 
Nostrils large, in the posterior half of the bill, their centre about opposite the middle of the commissure. Tertials long, 
lanceolate, and straight. Tail pointed, of 14 feathers, the central feathers very long, equal to the wings. Bill with almost no 
posterior lateral upper angle ; the feathers of the sides advancing obliquely forwards. Feathers of chin reaching beyond the 
middle of the commissure, or almost to the anterior extremity of nostrils. Tail of 14 feathers. 
The genus Harelda, of Leach, is stated by Gray to have been established in 1816, probably 
in the "Catalogue of British Museum." If not published until 1824, in Shaw's General 
Zoology, the name will be anticipated by Clangula of Fleming, 1822. 
The characters of the single species are as follows : 
Summer. — Blackish ; the belly and sides whitish. Scapulars and lower part of back with 
rufous edgings. A grayish patch on the side of head, passing behind into whitish. No white 
spots, nor speculum. Inside of wing, and axillars, dark brown. 
Winter. — Similar, but with the head, neck, and scapulars, whitish.......... H. glacialis.
