Podiceps gularis, Gould in Proc. of Zool. Soc, Part V., 1 837. 
Remark. The above description answers to the spring or nuptial dress, which is common to both 
sexes ; at other seasons the rich markings of the head give place to a uniform tint of greyish brown, 
and the general colouring is also much lighter. 
Habitat. Australia : locality. New South Wales. 
PODICEPS NESTOR, Gould. 
Fig. 2. 
Pod. capite plumis elongatis sericeis albis induto ; gutture et occipite nigris ; corpore supra intense 
brunneo, subtiis argenteo-griseo, ad latera brunneo lavato ; rostra nigra ad apicem pallidiore ; 
tarsis olivaceo-nigris. 
Long. tot. 9 unc. ; rostri, 1 ; ala;, 4^ ; tarsi, 1§. 
Head covered with long fine hair-like white feathers ; throat and occiput, upper surface dark brown, 
under surface silvery grey, tinged with brown on the flanks ; bill black with a light tip ; tarsi blackish 
olive. 
Podiceps Nestor, Gould in Proc. of Zool. Soc, Part V., 1837. 
Remark. The above is the plumage of the breeding-season ; at other periods the head is plain brown, 
and destitute of the elongated hair-like feathers. 
The Podiceps poliocephalus of Messrs. Jardine and Selby's Illustrations of Ornithology (vol. i. pi. 13.) 
may possibly be identical with the present bird in one of its changes ; at the same time this point is 
not so clear that we could feel satisfied in figuring it vmder their name. 
Habitat, Australia : localities, Van Diemen's Land and New South Wales.
