PUFFINUS CINEREUS.
point so as to correspond with the upper, its apex slender and acute, no
prominent angle behind apex inferiorly. Tarsi somewhat compressed, and
coated with moderately large polygonal scales. Toes, superiorly, covered
partly with irregular shaped scales, and partly with transverse scutes: the
interdigital membranes near the toes coated with irregular sized scales, those
along the inside of outer toe largest; claws pointed and slightly curved, the
hinder one somewhat triangular, and placed upon the tarsus. Wings long, and
when folded extend nearly an inch and a half beyond the tail, first quill
feather longest. Tail rounded, the two middle feathers nearly three quarters
of an inch longer than the external one of each side.

I hesitated long before I came to the determination to regard this bird as the young of P r o -
cellaria puffinus, especially as Temminck, whose knowledge must be held in great respect by
every naturalist, makes the young “ peu t-ê tre d 'u n a n ” as very differently coloured from what it
must be considered, if our conclusion be correct. His bird of the first year will, if we are not
in error, be one of the second year, and Plate 962 of the “ Pla n c h e s enluminées” will be the representation
of a specimen which has attained its second plumage. Specimens in the garb we have
described are common on the Cape seas, and generally seen in company with others, which are
doubtless genuine examples of P . cinerea ; and one of the latter which we possess has tended
more than any thing else to satisfy me that the bird just described is the young of the species,
as in it the middle of the belly and flanks retain the immature plumage, though elsewhere the
feathers have acquired the colours of the adult bird. There are persons who consider it superfluous
to represent the young of a species when the adult has been figured, but we disclaim
such a belief; we consider information concerning the aspects under which a species appears to
be as essential for the naturalist as the knowledge of new species : indeed, until more attention
be paid to that, we shall have among the species introduced from day to day many which
will be found to be only specimens of known species in particular stages.
