This fairly reviews the state of affairs at 1840, when Gray {fJst Gen. Birds 

 p. 77) typified the various geoera previously proposed. Omitting all reference to 

 Penguiims Biiinnich, Apterodita Scopoli, or Chrtjsocoma Ste[)hens, he accei)ted four 

 genera as follows : — 



Spliciiiscas Briss. Type <S'. demersus (L.) Tenim. 



Ei(di/ptes Vieill. „ E. chnjsocoine (Forster) Vieill. 



Pi/goscdis Wagl. „ P. papua (Forster) Wagl. 



ApUnodytei Forster. ,, A. pntnchonica (Forster). 



If this action be allowed to overrule Vieillot's disposition, which seems to be 

 a matter for more consideration, we arrive at the foliowiug : — 



Peiigiiinas Briinnicb, 1772. Type Pit- demersi/s Linne. 



The synonymy includes Catarractes Scopoli, 1777; Eudi/ptes Vieill., 181(5; 

 Chri/goroma .Stephens, 1826. 



Spheniscus Briinnich, 1772. Type D. demersa Linne. 



Tills is Sphenisciis of Brissou and most recent authors. 



AptcHodijtes Forster, 1781. Type A. patacho/iicd Forster. 



As synonyms may be noted Apterodita'&co^oW, 178G ; Pii/guinaria Shaw, 1793. 

 I'l/goscelis Wagler, 1832. Type A. papua Forster. 



This arrangement only necessitates the introduction of Pengiiinus Briiunich 

 vice Catarractes Brisson into the nomenclature as at present generally accepted. 

 Recognition of Vieillot's separation will incur many other changes, and, if necessary, 

 these must be made at once.

 In the Amer.'O. L'. Chech Li.tt 3rd Ed. I9li) Thalas.i.eas Boie has been accepted 

 instead of Hydroprogne, but clearly the matter requires reconsideration. I make 

 out the claim of llgdroprogne to stand as follows: Thala,<ii<iiti>t was introduced by 

 Boie in the Isiis 1822 p. 503 for three species, ca.spia, cantiaca, and anglica. Kaup
