tarsus 3.70; middle or outer toe and claw 4.50; inner do. 4.00. Wing 19.00-20.00; tail about 
6.50. Pacific coast of N. Am., abundant.

Bill comparatively slender, strongly compressed, with sharp culmen ; side of under mandible 
with a long colored groove. Frontal feathers forming a deep acute reentrance on culmen; 
a long acute salience on side of lower mandible. Nostrils low and strict. Tail cuneate, 
contained twice in the length of wing. Plumage uniformly dark. One species. 
812. P. fuligino'sa. (Lat. fuUgmosa, sooty. Fig. 523.) Sooty Albatross. Bill with shape 
and outline of feathers as above said ; chord of culmen 4.00-4.50; height of bill at base 1.50, 
at hook 1.00; width at base 0.75 ; from feathers on side of upper mandible to tip 3.50, ditto 
lower mandible 2.50. Wing 20.00-22.00 ; tail 10.00-11.00, graduated 3.50-4.50 ; tarsus about 
3.00; middle toe and claw 4.75, outer do. 4.50, inner do. 4.00. Plumage ordinarily uniform 
sooty-brown ; quills and tail blackish with white shafts ; eyelids white ; bill black, with 
long yellow (perhaps in life pink or red) groove : feet pale or flesh -color, drying yelloM\ 
In some cases the plumage lightens to a clearer more ashy-gray coloration on various parts. 
The head and neck frequently washed with rusty-yellow. Pacific ocean at large; oflf coast 
of N. Am. 
75. Subfamily PROCELLARIIN>E : Petrels. 
Nostrils united in one double-barrelled tube laid horizontally on the culmen at base. 
Hallux present, though it may be minute. Five groups of petrels may be distinguished, 
although they grade into each other ; four of them are abundantly represented on our coasts. 
The fulmars are large gull-like species (one of them might be taken for a gull were it not 
for the nostrils), usually white with a darker mantle, the tail large, well formed (of 14-16 
feathers), the nasal case prominent, with a thin partition. They shade into the group of 
which the genus (Estrelata is typical, embracing a large number of medium -sized species, 
chiefly of Southern seas, in which the bill is short, stout, very strongly hooked, with prominent 
nasal case; the tail rather long, usually graduated. The shearwaters (Pufinus) have the 
bill longer than usual, comparatively slender, with short low nasal case, obliquely truncate 
at the end, and the partition between the nostrils thick ; the tail short and rounded ; the 
wings extremely long; the feet large. The elegant little ''Mother Carey's chickens'' or 
"stormy petrels" Thalassidroma" of authors; Procellaria proper and its relatives) are 
a fourth group, marked by their small size, slight build, and other characters; their flight 
is peculiarly airy and flickering, more like that of a butterfly than of ordinary birds ; they 
are almost always seen on wing, appear to swim little if any, and some, if not all, breed 
in holes in the ground, apparently like bank swallows. Like other petrels they gather in 
troops about vessels at sea, often following their course for many miles, to pick up the refuse 
of the cook's galley. Some of them, as the species of Oceanites, have remarkably long legs, 
with fused scutella, flat obtuse claM^s, and the hallux exceedingly minute ; in the rest, the 
feet are of an ordinary character. The exotic genus Pi'ion typifies a fifth group, of five or 
six species ; here the bill is expanded, and furnished with strong laminae, like a duck's ; the 
colors are bluish and white.
