Areas 
Three areas are recognized in the Southern Superarea, 
namely, Circumpolar Area, Indo-Pacific Area, and South 
Atlantic Area, and two in the Northern Superarea, namely, 
North Pacific Area and North Atlantic Area. The bound- 
aries are necessarily more or less tentative, owing to our im- 
perfect knowledge of the breeding stations of many species. 
The Circumpolar Area lies chiefly between parallels 78° S. - 
and 40° S., and includes Tristan da Cunha, but not Chatham, 
South, or Stewart islands, New Zealand, or Tasmania. Its 
northern boundary coincides well with the isotherm of 15° C. 
for January. The climatic conditions are Antarctic and sub- 
Antarctic. The following are apparently characteristic species: 
Thalassarche melanophris Halobena cerulea 
Thalassarche bulleri Pagodroma nivea 
Thalassarche culminata Pterodroma lessoni 
Pheebetria palpebrata Pterodroma brevirostris 
Macronectes giganteus Procellaria equinoctialis 
Priocella antarctica Puffinus gravis 
Thalassoica antarctica Oceanites oceanicus 
Petrella capensis 
The Indo-Pacific Area embraces approximately the Indian 
and Pacific oceans south of the Equator and north of the 
isotherm of 15° C. for January, including the immediate 
vicinity of Stewart, South, and Chatham islands, New Zea-
