Genus — P AGODROMA. 
Pagodroma Bonaparte, Gomptes Rendus Sci., Paris, 
Vol. XLII., p. 768, 1856 . . . . . . . . Type P. nivea (Forster). 
This genus is recognisable by its resemblance to Pterodroma, but from which it 
is easily differentiated by its comparatively short, high, and very compressed 
bill, its more strongly developed hallux, and the coarse scuteUations on the 
tarsus and feet. It has usually been considered a monotypic genus. 
Hitherto only one species has been recognised, and the authority quoted 
as Gmelin, but I find the earliest description was published by Forster, and the 
correet reference should read Procellaria nivea Forster, Voyage Round the World, 
Vol. I., pp. 96 and 98, 1777, where it is thus described: “A petrel about the size 
of a pigeon, entirely white with a black biU and blueish feet ; its colour induced 
us to caU it the snowy petrel ” ; thereafter named Procellaria nivea. Forster’s 
detailed description was not pubhshed until the Descr. Anim. were edited by 
Lichtenstein in 1844, when we find the following account (p. 58) : — 
Dec. 1772. Procellaria nivea F. Fig. picta G. The Snowy Petrel or Snowbird. 
Procellaria tota nivea, rostro atro, pedibus glaueis. 
Habitat in Oceano antarctico a gradu Latitudinis australis 62 usque in circulum 
Antarcticum, plerumque observavimus eas in vicinia glaciei.

The “ Fig. picta G ” refers to paintings made by George Forster, and we 
find one finished and one unfinished picture in the Banksian collection. 
No. 90 is a pencil-drawing of a flying Petrel with ship and icebergs in the 
background. It is not quite accurate in its details, such as the shape of the 
biU and the proportions, and agrees with the suggestion that it was drawn 
on December 11th, 1772, as I noted the foUowing in Cook's Voyage Bound the
