Photo by D. R. Dickey 
along the entire coast, and upon some of the rocky headlands. Especially numerous 
on the Farallons. Occurs casually in the interior. 
Authorities.—Lawrence {Lams occidentalis), in Baird, Rep. Pac. R. R. Surv., 
vol. ix., 1858, p. 845 (Bodega; Presidio; San Diego); W. E. Bryant, Proc. Calif. Acad. 
Sci., ser. 2, i., 1888, p. 37 (Farallon Ids., breeding; nest and eggs). 
No. 274a Hyperion Gull 
A. O. U. No. 49, part. Larus occidentalis livens Dwight. 
Synonym.— Dwight’s Western Gull. 
Description. —“Similar to Larus occidentalis occidentalis, but mantle a darker 
plumbeous or deep neutral instead of plain neutral gray and usually four outer pri¬ 
maries, instead of two, black basally without gray areas” (Dwight). 
Range. — Both coasts of Lower California, breeding north to the Farallon Islands. 
Authority.—Dwight, Proc. Biol. Soc. Wash., vol. 32, Feb. 14, 1919, pp. 11-14. 
[Under the particular description (p. 12) we read: “Tarsi and feet in life lemon yellow,” 
and again, “Both forms of occidentalis have yellow feet (the tarsus of the type of livens 
is recorded by the collector as ‘lemon yellow’).” Again, “Apparently Schlegel (Mus. 
Pays. Bas, vi., 1863, p. 15) was the first writer to correctly describe the species as having 
yellow feet.” All this, of course, is exquisitely incorrect. The feet of all adult gulls 
of the occidentalis type are red].
