Forster, Comm. Society Reg. Scient. Gotting., vol. in, p. 781, 

 characterizes the genus Aptenodytes, and gives descriptions of the 

 following species : — 



CRISTATE. 



Aptenodytes chrysocoma. 



ALOPEL^. 



Aptenodytes patachonica. 



Aptenodytes patagonica Miiller. 

 Aptenodytes papua. 

 Aptenodytes antarctica. 

 Aptenodytes magellanicus. 

 Aptenodytes demersus. 



Spheniscus ncevius Briss. 



Diomedea demersa Linn. 

 Aptenodytes catarractes. 



Phaeton demersus Linn. 

 Aptenodytes torquata. 



S. demersus, var. 

 Aptenodytes minor. 



The name Aptenodytes must belong to A. patagonica, since A. 

 chrysocoma is of the same group as Catarractes Briss., Splieniscus 

 catarractes Schl. The genus Pinguinaria has for a type Pinguinarla 

 patachonica Shaw, Nat. Miscel., vol. iv, pi. 409, Dec. 1799. Refer- 

 ence is also made to Mus. Leverianum, No. 3, t. 144, p. 11, for first 

 description P. patagonica, but this I have not seen. 



Eudyptes, Vieillot, Analyse, etc., 1816, p. 67, is the first tenable 

 distinctive name of the crested genus. In 1825, according to Gray, 

 Vieillot used Brisson's original name of Catarractes, which, however, 

 is antedated by Moehring (1752) for a genus of Alcidae. 



Stephens, in Shaw's General Zoology, 1825, established a new 

 genus from the same group, Chrysocoma, which, however, also in- 

 cluded Spheniscus minor. 



Whether Vieillot included in Eudyptes species which were not 

 plumed on the head I cannot say, not having had access to his work. 



Pygoscelis has Wagler's authority. From an extract in the Isis, 

 1832, it may be seen that the characteristics are the '•' gestalt" of 

 the beak and the length of the tail. These characteristics are taken 

 from Wagler's Nat. Syst. d. Amph., to which I have not had access. 

 The type is Aptenodytes papua Forster.
