DR. GAMBEL ON THE BIRDS OF CALIFORNIA. 227 



CARBO. 



168. C. DiLOPHUS, Swains. Common double-crested Cormorant. 



Phalacrocorax Townsendii, Aud. Bds. Amer. pi. 412, fig. 2. Young. 



This species is common both to the Atlantic and Pacific coasts of North America, 

 specimens from Oregon and California are identical with those of Florida. 



Although the double-crested Cormorant of North America was first figured by 

 Vieillot in the Gal. des Ois., pi. 275, yet, strangely enough, the text of the book does 

 not correspond to the plate, and the bird described by Vieillot under that name, is 

 the beautiful C. punctatus of New Zealand. It is copied from the Nouv. Die. d'hist. 

 Nat. vol. viii. p. 5, where he unnecessarily changes the old name punctatus. 



Swainson, apparently unaware that the name diloplms had been given by Vieillot 

 to the spotted shag, or that the North American one was figured, by mistake I 

 suppose, in the Gal. des Ois., first described our bird* under the name dilophus, and 

 and is therefore entitled to the name. 



170. C. PENICILLATUS, Brandt. 



This species is readily distinguished during the breeding season by the delicate 

 white linear feathers which are developed upon the sides of the neck and scapulars. 

 It is common at Monterey and other places in California. 



PELECANUS, Linn. 



171. P. TRACHYRHYNCHUs, Lath. Rough-billcd Pelican. 



P. Americanus, Aud. Bds. Amer. pi. 311. 

 Common. 



172. P. FUSCTjsi, Linn. Brown Pelican. 

 Abundant. 



SULA, Briss. 



173. S. FuscA, Briss. Booby. 

 Common off the coast. 



ZACHYPETUS, Vieill. 



174. T. AQUiLUS, Vieill. Frigate Pelican. 



These birds are extremely abundant at Mazatlan, and about the Gulf of California, 

 and so daring were they, while we were hauling the seine, as to pounce down and 

 seize the fish from within a few feet of us. On a clear day they may be seen in 

 <Teat numbers, soaring at a great height in the air, sometimes almost out of sight.
