PRO CELLAR I A HASITATA, Kuhl 
Great Grey Petrel. 
Procellaria hasitata, Kuhl, Forst. Drawings, No. 92.— Gould in Ann. and Mag. of Nat. Hist., vol. xiii. p. 364. 
This species, which is very similar to the Puffinus cmereus, enjoys so wide a range of habitat that it may be 
said to be universally diffused between the 30th and 55th degrees of S. latitude. I first observed it in lat. 
38° 41' S., long. 36° 30' W., on the 16th of August 1838 ; during the next five days not more than a single 
specimen was seen at one time; on the 21st it was very numerous, and the day being nearly calm I had a 
boat lowered, and succeeded in killing several in lat. 39° 23' S., long. 54° W. Its powers of flight are very 
great, and in its passage over the ocean it often mounts higher in the air than most other members of the 
group, and descends again with the utmost eagerness to seize any fat substance thrown overboard. Its 
actions and flight differ slightly from those of the other Petrels, and more closely resemble those of the 
Albatroses. 
I subsequently observed this bird in lat. 41° 12' S., long. 115° W., and obtained specimens on my passage 
from Hobart Town to Sydney. 
On my voyage homeward it appeared in considerable numbers during some strong heavy gales which 
occurred on the 6th of May 1840 in lat. 40° S., long. 154° W., and it was very abundant in the South Atlantic 
on the 12th of June in lat. 41° S., long. 34^° W. 
Little or no difference is observable in the sexes, but the female is rather smaller than the male. 
Crown of the head, ear-coverts, nape and upper surface, tips of the tail-feathers, tips of the under tail- 
coverts and the primaries dark brownish grey ; throat, chest and under surface white ; irides dark brown ; 
culmen and nostrils black; tip of the upper mandible blackish horn-colour; tomia whitish horn-colour ; 
lower part of the under mandible blackish horn-colour ; feet white, tinged with blue, the outer toe brownish 
black. 
The Plate represents a male of the natural size.
