The auk-like Petrels constituting the family Pelecanoididce are such a distinct 
group, that doubt has been cast upon the accuracy of their inclusion in the 
order Procellariiformes. They possess tubular nostrils, otherwise they disagree 
in general appearance with other members of the order. 
They are small birds in which the head is longer than the bill, the wings 
and tail are short, the latter square, and the plumage glossy and compact. 
They are recognisable at sight, as in addition to these features, the nostrils are 
perfectly vertical, and more or less kidney-shaped. 
A beautiful detailed description of the biU is given by Coues {Proc. Acad. 
Nat. Sci. Philad. 1866, p. 189), and I would here only note the differences 
between the species P. urinatrix and P. garnotii in that feature. The 
former has the nostrils elongate, narrow and parallel the distensible sac con- 
tained by the rami of the under-mandible is pronounced and unfeathered. 
The latter has a longer bill with the nostrils less elongate proportionately, 
and more triangular shaped, with a noticeable projection from the inner 
edge ; this can also be seen in the preceding species, but it is very minute.

Puffinuria garnotii. 
In addition the rami of the lower mandible do not enclose a wide distensible 
sac, which is also partly feathered. When Lesson described this latter species 
he proposed the genus-name Puffinuria, as he noted his birds did not agree
