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 nrophasiana (Vig.), 1829. Northwest coast.” This 
South American species has not been confirmed as from North America, 
and, if found, occurs only as a straggler. 
62. Larns 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. Laridae), 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 nigrum” (Coues). Saunders (Proc. Zool. Soc. 1876, 
p. 642) makes them identical (Lawrence).] 
66. Xema furcatum {Neboux), 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, Yieill. “ 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, Lut not farther north, and I have not seen them 
along the coast north of lat. 30° during several voyages. 
70. Diomedea chlororhyncha {Gmel.). “ Off the coast of Oregon,” •
