tuted ; the name holds for the crested group, if these are con- 

 sidered worthy of generic rank. 



1820-26. Vieillot, Galerie, etc. Aptenodytes papua, Sco-p.is 

 figured (pi. 299). 



1825. Stephens, Cont. of Shaw's Gen. Zool. Genus Ghryso- 

 coma, a synonym of Eudyptes, Y., 1816, is instituted. 



1825. Weddell, Froriep's Notizen, xii. 198. On species of Ap- 

 tenodytes, etc., from the South Georgians. 



1832. Wagler, Isis. A genus, Pygoscelis, is based upon Apte- 

 nodytes papua, Scop. 



1833. Yarrell, P. Z. S. i. 33, 65. On the hairy and woolly 

 penguins of Latham. 



1834. Bennett, P. Z. S. ii. 34. Habits of Aptenodytes. 



1834. Meyen, Nova Acta Acad. Gses. Leop.-Garol. xvi. supp. 

 i. 110, pi. 21. A species is named Spheniscus humboldtii, from 

 Peru ; it is a synonym of S. demersus. The author, indeed, 

 remarks upon the likelihood of its being the same as P. E. 382. 

 I have seen specimens precisely like the plate here given. 



1835. Reid, P. Z. S.i'n. 132. Anatomy of Apt. patagonica. 

 1831. Brandt, Bull. Acad. Sc. St. Petersb. ii. 305. A very 



important and valuable contribution, like the rest of this emi- 

 nent naturalist's publications. A new species, Gatarractes chry- 

 solophus (the first valid new one for half a century!) is described. 



1841. Hombron and Jacquinot, Ann. Sc. Nat. xii. p. 320. A 

 notable article. Two valid new species are described, viz., Gatar- 

 ractes adelise and G. antipodes, raising the number of known 

 species to eleven. A few years subsequently (1846), these species 

 are figured by the same authors (Yoy. Pole Sud, pi. 33), and one 

 of them (adelise) is made the tj^pe of a new genus, Dasyrliamphus. 

 (See also Comptes Bendus, 1841, xiii. 360, on the same species.) 



1842. Gloger, . Institutes the genus Dypsicles, type de- 

 mersus. (According to Gray ; I have no means of verifying the 

 citation.) 



184-. Gray, Voyage of the Erebus and Terror, Birds. In 

 this very acceptable contribution, Mr. Gray figures three of the 

 previously known species, viz., papua, antarctica, and antipodes, 

 in pis. 25, 26, 2T respectively, and describes and figures a new 

 species, Pygoscelis brevirostris, pi. 28 ; this last, however, is identi- 

 cal with adelise, as the author soon discovered. He also describes 

 another new species, Eudyptes pachyrhyncha, p. 11 ; and the
