name will stand, if, as Mr. Gray holds, chrysocome and catarractes 

 Forst., Gm. and Lath., are the same bird ; but I cannot agree 

 with him here. I think that these older authors had two species 

 in view, and that their chrysocome is what Gray here names 

 pachyrhyncha. 



1844. Lichtenstein, Edit. Forster's Descr. Anim. In this re- 

 presentation of Forster's labors, among other things, two new 

 names are proposed, but neither of them stands. Aptenodytes 

 patpebrata, from the Cape of Good Hope, is the original Linnsean 

 Diomedea demersa, whilst A. brasiliensis is a variety of the same 

 species, equivalent to the old torquata or magellanicus of Forster. 



1844. Gray, Am. Mag. Nat. Hist. xiii. 315. The author care- 

 fully distinguishes the two species of Aptenodytes, calling one of 

 them for steri, a name anticipated by patachonica, Forst. ; and the 

 other pennantii, which is antedated b} r longirostris of Scopoli. 



1844. Gould, P. Z. S. xii. 87. Description of a new species, 

 Apt. undina; it is the same as Apt. minor, Forst. 



1848. Peale, Ornith. of the U. S. Expl. Exped. As ornitho- 

 logists are aware, the Ornithology of the Wilkes's Expedition was 

 " official^" cancelled by the United States Government, and the 

 edition was recalled as far as possible, on account of the unsatis- 

 factory manner in which the author of the work was considered to 

 have performed his task. But the attempted suppression proved 

 impossible ; the work is extant, and must be recognized. In his 

 treatment of the penguins, Mr. Peale shows his familiarity with 

 the birds themselves, but unfortunately some ignorance of orni- 

 thological literature. With a copy of his work before us, and 

 all his original specimens, now in the Smithsonian, we find that 

 he has discriminated the species with perfect accuracy; and he 

 gives many new and interesting biographical data. His short- 

 comings are soleby in the matter of nomenclature. We are enabled 

 to make the following determinations: 



A. magnirostris, Peale, = Sph. demersus, var. magellanicus. 



"A. chrysocome, Gm.?" Peale, = Eudyptes catarractes. 



A. flavilarvata, Peale, = Pygoscelis antipodes (II. and J.) 



A. longicaudata, Peale, = Pygoscelis adelise (II. and J.) 



A. t^gniata, Peale, = Aptenodytes papua of Scopoli, but the 

 name must stand, since Scopoli's is geographically inapplicable. 

 Peale's other names are correct; his patagoniea is Forster's bird, 

 the true " emperor penguin."
