to be universally diffused between the 30tli and 55th degrees of 

 S. lat. 



Procellaria flavirostris, n. sp. — Feathers of the head and all the 

 upper surface brown with paler edges^ fading into white on the 

 tips of the upper tail-coverts ; wings and tail deep blackish brown ; 

 all the under surface pure white; the feathers of the under sur- 

 face of the shoulder with a streak of brown down the centre ; bill 

 yellow, passing into dark horn-colour at the tip ; tarsi and feet 

 fleshy white. 



Total length 19 inches ; bill 2| ; wing 15 ; tail 6^ ; tarsi 2| ; 

 middle toe and nail 3^. 



This fine species was procured ofi* the Cape of Good Hope, in 

 lat. 36° 39' S., long. 10'3'E., by His Excellency Governor Grey, 

 on his passage to South Australia. It is distinguished from its 

 congeners by its much larger size, and by the yellow colouring of 

 the bill. The female is somewhat smaller than her mate. 



This bird so nearly approaches in form the members of the 

 genus PuffinuSy that it is almost questionable whether it should 

 not be included in that group. 



Procellaria Antarctica, Gmel. — Inhabits the whole of the frozen 

 regions of the Antarctic circle, out of which it is rarely to be met 

 with. 



Procellaria Glacialoides, Smith. — Abundant between the 30th 

 and 50th degrees of S. lat. I have a specimen killed at New 

 Zealand, and I observed it to increase in numbers as we ap- 

 proached Cape Horn ; it is also equally abundant off the Cape of 

 Good Hope. I caught many of this species with the hook and 

 line. 



Procellaria nivea, Gmel. — An inhabitant of the icy regions of 

 the Antarctic circle. My specimens difi*er so much in size as to 

 suggest the idea that there may be more than one species of these 

 snow-white Petrels. 



Puffinus brevicaudus, n. sp. — Found in all the Australian seas, 

 and breeds in the greatest abundance on several of the islands 

 in Basses Straits. 



Puffinus carneipes, Gould in Proc. of Zool. Soc. March 26, 1844, 

 n. sp. — The whole of the plumage chocolate- black ; bill fleshy 

 white j the culmen and tips of the mandibles brown ; legs, feet 

 and membranes yellowish flesh-colour. 



Total length 15 inches; bill 1|; wing 12; tail 5; tarsi 2; mid- 

 dle toe and nail 2^. 



Numerous on the seas bounding the western coast of Australia, 

 and breeding on the small islands off Cape Leeuwin, where my 

 specimens were procured. 



Puffinus sphenurus, n. sp. — All the upper surface dark choco- 

 late-brown, which gradually deepens into black on the primaries
