may somewhat resemble the pouch of the pelican. 
The birds of the next two families have very long wings^ 
and are capable in consequence of protracted flight. Many 
of them are found on the ocean at great distances from the 
land. To this section Cuvier has applied the name of 
LoNGiPENNES, from the long wings^ which are so charac- 
teristic of the group. 
The family PEOCELLAEiDiE contains the Petrels and Al- 
batrosseSj — birds which have longish beaks^ hooked at the 
tip, and the extremity looking as if a piece had been articu- 
lated to it ; the nostrils are tubular, sometimes united and 
opening by a common orifice, or separated, and opening by 
two distinct holes; the hind toe is either reduced to a 
claw, or, as in the albatross, is absent. The species are 
much more numerous than was at one time supposed, and 
they are dispersed widely. Mr. Macgillivray indeed believes 
that some of the species make the circuit of the globe, as he 
has met wdth at least five of the family which are common 
to the South Indian and the South Pacific Oceans'^. He 
says that he has ahnost invariably found in the stomachs of 
the many albatrosses, petrels, and shearwaters which he has
