BULLETIN OF THE NUTTALL 
41. Dryotomus delattri, Bonap., 1854. Doubtless labelled “ Califor- 
nia” by error for Nicaragua. 
42. Campephilus imperialis ((tOmW), 1832. “California^” And., 1839, 
Nutt., 1840, Cassin (figured), 1855. Although Nuttall states that Towns- 
end shot a specimen in the Rocky Mountains, near the head of the Colo- 
rado River, it is not mentioned in Townsend’s List, nor figured by Au- 
dubon. Townsend, however, states that he shot, but lost, a Woodpecker 
resembling this on Malade River (now in Idaho). Cassin gives reasons for 
supposing it may also occur in California, and it is to be looked for in 
Arizona. 
43. Melanerpes erythrocephalus {Linn.). “ California,” Gainbel, 
1847, Baird in Ornith. of Cal., 1870. Dr. Gambel does not seem to have 
preserved any specimens, and as no later collectors have found it west of 
Salt Lake City (“ one seen,” Ridgway), its occurrence in California must be 
merely accidental. 
44. Ceryle americana (Gmel.). “ Colorado River,” Coues, 1866. As 
Dr. Coues only thought he saw this species along the river, and as such a 
large bird could scarcely escape the many collectors who have been at F ort 
Yuma and along the Gila River (whose clear wnters are better suited for 
it than the muddy Colorado), we may doubt its occurrence until speci- 
mens are obtained, its range in Texas not being north of lat. 30°. 
45. Haliaetus pelagicus (Pall.), 1831. “Aleutian Islands.” Al- 
though not obtained by late collectors in that region, its occurrence as a 
frequent visitor from Kamtschatka is more probable even than that of H. 
albicilla to Greenland, and it may be looked for at least as far south as 
lat. 50° on our coast. 
46. Syrnium nebulosum (Forst). “California,” Woodhouse, 1853. 
The birds seen by him in .Arizona, also, ’were probably S. occidentale, 
Xantus, 1859. See Baird in Orn. of Cal., 1870, p. 431. There are several 
instances besides this in which southern species of Owls do not extend 
across the continent, although those of the arctic regions, being mostly 
circumpolar, are common to both sides. Thus Nyctale tengmalmi might 
have been included in the Orn. of Cal. instead of this, it having been found 
in Oregon by Townsend. 
47. Catharista atrata (Bartr.). “ Columbia River,” Douglass in Faun. 
Bor. Am., 1831, And., 1839, Peale, 1848, Cassin, 111., 1853, 1858. It is 
possible that these references were to the young of Ehinogryphus aura., 
although an actual specimen seems to be alluded to. Dr. Gambel found 
it quite common about the Gulf of California, but does not add California 
as in other cases, nor has it been detected, though very likely to be, along 
the Colorado. 
48. Baroorhamphus gryphua {Linn.). “ Southwestern States,” 
Bonap., 1828-33; “Rocky Mountains,” 1832-40, quoting Lewis and 
Clarke’s “ bustards,” and the bill and talons brought by them to Peak’s 
Museum. These were, however, probably those of Pseudogryphus califor-
