Genus— PENGUINUS. 
Penguinus Brimnich, Zool. Fund., p. 78 (1772)* 
E'udyptes Vieillot, Analyse, p. 67 (1816). . 
Chrysocome Stephens, in Shaw’s Gen. Zool., XIII., p. 57 (1826) 
Microdyptes Milne-Edwards, Ann. Sci. Nat. (6), IX., Art. 9,

P. chrysocome, 
P. chrysocoyne. 
P, chrysocome. 
P. serresiana. 
Bill short and very thick, the latericorn of the upper mandible swollen. The 
fourteen to sixteen rectrices are much longer than the tad-coverts, which are 
short. Above the eyes, on each side of the head, a more or less elongated 
tuft of feathers. Five species. 
Distribution. From Tierra del Fuego to the Australian region. 
* Linn6, in the lOtli ed. of his Syst. Nat., p. 135 (1758), described Phaethon demersus, which though 
undoubtedly a “ Crested Penguin,” is obviously a young bird, and unfortunately must be regarded as indeter- 
minable. Brunnich’s genus Penguinus was certainly founded on the characters of this bird, but as no species 
was named by him, I herewith designate Aptenodytes chrysocome Forster as the type of Brunnich’s genus, 
have fully discussed the technical points of this matter elsewhere (Vow. .ZooZ., xvii., p. 495 (1910) ), and there 
accepted P. demersus Linn6 as the type of Penguinus as I identified Forster’s P. chrysocome with Linn5’s species. 
The course I now advocate I consider better, as tending to give more stability to our nomenclature.
