CINEREOUS SHEARWATER. 
Puffinus cinereus, Steph. 
Le Petrel Puffin. 
Ir it should ultimately appear that the bird obtained by Mr. Strickland from the Tees mouth, and charac- 
terized by him, in the Proceedings of the Zool. Soc. for 1832, under the new specific title of Pujfinus fuliginosus, 
is identical with the young of Puffinus cinereus, a circumstance which is by no means unlikely; and if a 
bird apparently in the adult plumage, subsequently obtained by the same gentleman, should prove to be the 
adult of this species, we shall have, with the addition of a specimen obtained by Mr. Selby, three examples 
of British-killed specimens of this species. Wath respect to the specimens forwarded by Mr. Strickland, 
and which we have figured, we have to observe, that these two birds, although agreeing in their admeasure- 
ments with each other, differ slightly from a specimen of Puffinus cinereus sent to us by M. Temminck as an 
undoubted example of that species, Mr. Strickland’s specimens being less in all their admeasurements ; and 
could we have discovered any difference in the markings of their plumage, we should have had no hesitation in 
regarding them as distinct: as it is, we have here figured both Mr. Strickland’s birds as one and the same 
species, but with a mark of doubt as to their being examples of the true Puffinus cinereus. 
The range of the true Puffinus cinereus according to M. Temminck is very extensive: “‘it is spread through- 
out the Mediterranean, it often appears on the southern coast of Spain and on those of Provence, where 
many individuals have been killed. It is never seen in the Adriatic. Specimens killed in Senegal and those 
from the Cape of Good Hope differ in no respect from those killed in Provence. The habits and manners 
as well as the food of this species do not differ from those of its nearly allied species the Manx Shear- 
water, Pufinus Anglorum, which, as is well known, feeds on all kinds of marine animal matter in a state of 
putrescency. | } | 
The head, cheeks, and all the upper surface pale ash grey, the edges of the feathers on the back being 
lighter on their external margins, the scapulars, wings, and tail darker; quills deep black; on the sides of 
the neck and chest are waves of light grey; under-surface pure white; beak yellowish, becoming browner 
towards the tip; feet and interdigital membrane livid yellow, the webs lightest in colour; irides brown. 
Our figures are rather less than the natural size.
