96 BULLETIN OF THE NUTTALL 



California, and not very likely to straggle so far north, although Tantalus 

 loculator visits San Francisco Bay and vicinity every year. Could he 

 have been deceived by hearing Spatula clypeata called " Spoon-bill " ? 



59. Anser segetum (Gmel.). " Probably on Northwest coast in winter," 

 Nuttall, 1832. The evidence for the occurrence of this species anywhere 

 in North America is very slight, although it is quoted by Swainson and 

 Richardson from Hearne. [Doubtless A. canadensis (Cones).] 



60. Anas obscura, Gmel. " Oregon," And., 1839, Townsend's List, 

 " California," Woodhouse, 1853. This, probably a melanistic form of 

 the Mallard, has not recently been found west of Utah. (See Henshaw, 

 Kept., 1875.) 



61. Dafila urophasiana {Virj.), 1829. " Northwest coast." This 

 South American species has not been confirmed as from North America, 

 and, if found, occurs only as a straggler. 



62. Iiarus belcheri, Vig., 1829. " Pacific coast of North America." 

 Though confounded by some with L. heermanni, this species is probably 

 limited to South America, and the range of the two species does not 

 meet. 



63. Chroecocephalus atricilla (Linn.). " Colorado River," Coues, 

 1868, but not yet obtained on Pacific side north of Cape Saint Lucas. 



64. Sterna antillarum (Less.). In exactly the same category as the 

 last. 



65. Hydrochelidon nigrum (Linn.). "Oregon," Towns., 1839; 

 " California," Heermann, 1858. According to Coues (Mon. Laridse), the 

 common American bird is H. lariformis (Linn.), so that the H. nigrum is 

 not likely to occur, except as a straggler, in the West, where all I have 

 seen were the common kind. [This is probably what Townsend and 

 Heermann meant by " nirjrxim" (Coues). Saunders (Proc. Zool. Soc. 1876, 

 p. 642) makes them identical (Lawrence).] 



66. Xema furcatum (Nehoux), 1840. " Coast of California." As this 

 remarkable species has not been confirmed from the West coast, the 

 locality may well be doubted, like too many recorded by the same author. 

 [Recently stated by Salvin to be an inhabitant of the Gallapagos (Law- 

 rence).] 



67. Graculus carbo (Linn.). " Nootka Sound," Nutt, 1834, " Ore- 

 gon," Towns., 1839. Not confirmed by collections from the West coast, 

 and no doubt confounded with other species. 



68. Sula bassana (Linn.). "Northwest coast of America," Nutt., 

 1834. 



69. Sula fiber (Linn.) ^^fusca, Vieill. " Off coast of California from 

 San Francisco south," Newberry, 1857. The species seen were probably S. 

 piscator (Linn.), and S. cyanops, Sund., which have been obtained from the 

 West Mexican coast, but not farther north, and I have not seen them 

 along the coast north of lat. 30° during several voyages. 



70. Diomedea chlororhyucba (Gmel.). " Off the coast of Oregon,"
