94 BULLETIN OF THE NUTTALL 



41. Dryotomus delattri, i7o?trtjj., 1854. Doubtless labelled " Califor- 

 nia" by eiT<ir I'ur Niiaiai,nia. 



42. Campephilus imperialis {Gould), ISZ2. "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," Gambel, 

 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 Fort 

 Yuma and along the Gila River (whose clear waters 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. 

 alhicilla 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, Aud., 1839, Peale, 1848, Cassin, 111., 1853, 1858. It is 

 possible that these references Avere to the young of Ehinogryjjhus 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. Sarcorhamphus gryphus {Linn.). "Southwestern States," 

 Bonap., l«28-33; ''Rocky Mountains," 1832-40, quoting Lewis and 

 Clarke's " l)ustards," and the bill and talons brought by them to Peale's 

 Museum. These were, however, probably those of Pseudognjphus calif or-
