184 PACIFIC COAST AVIFAUNA No. 11 
gonio Pass, July 15, 1899 (Loomis, Auk, xtx, 1902, p. 83). The authenticity of 
the locality of capture has been doubted (see F. Stephens, Condor, tv, 1902, p. 
45). The species is not certainly known to occur nearer than the mountains of 
southeastern Arizona—in the Transition zone, whereas San Gorgonio Pass is 
Lower Sonoran, barely low Upper Sonoran at its highest part. 
39 (——) Archilochus violajugulum (Jeffries) 
VIOLET-THROATED HUMMINGBIRD 
Synonym—Trochilus violajugulum. 
Status—The type and only known specimen was obtained at Santa Barbara 
(J. A. Jeffries, Auk, v, 1888, p. 168). This specimen is with little doubt a 
hybrid, probably between Archilochus alexandri and Calypte anna (see Thayer 
and Bangs, Auk, xxiv, 1907, p. 313). 
40 (—_) Selasphorus floresii Gould 
FLorEsI HUMMINGBIRD 
Synonyms—Trochilus floresti; Selasphorus rubromitratus. 
Status—Three instances of the occurrence in California of this supposed 
species have been reported: male, near San Francisco, May, 1885 (W. E. Bryant, 
Forest & Stream, xxvi, 1886, p. 426) ; male, Haywards, February 20, 1901 (Emer- 
son, Condor, m, 1901, p. 68) ; Nicasio, Marin County, February 26, 1909 (W. P. 
Taylor, Auk, xxv1, 1909, p. 291). These examples may be accounted for as re- 
sulting from hybridization between Sclasphorus alleni and Calypte anna (see 
Thayer and Bangs, Auk, xxiv, 1907, p. 313; W. P. Taylor, loc. cit.; Ridgway, 
Auk, xxvi, 1909, p. 440). 
41 (432) Selasphorus platycercus (Swainson) 
BrOAD-TAILED HUMMINGBIRD 
Synonym—Trochilus platycercus. 
Status—Recorded from California three times: (1) Lake Tahoe, a female 
taken (J. G. Cooper, Proc. Calif. Acad. Sci., 1v, 1868, p. 7; and many repeti- 
tions). The identity in this case has already been doubted (by Henshaw, Rep. - 
Wheeler Sury., 1879, p. 311, who thought the bird might have been S. calliope). 
On January 6, 1908, I found in the U. S. National Museum a specimen (then un- 
catalogued), evidently a young male of S. rufus, but with the following in- 
scription upon the two sides of the label, in J. G. Cooper’s handwriting: ‘‘Selas- 
phorus platycercus 2 | Tajo Valley Cal. | Sept 12—1863—J. G. C. || 3 75 4 75 
1 87 Iris brown, bill | & Feet black’’. This bird would appear to have been 
the basis of Cooper’s record. 
(2) A. K. Fisher (N. Amer. Fauna no. 7, 1893, p. 58) records that this 
species was reported by Mr. Nelson ‘‘as common on the western slope of the 
Sierra Nevada, California, opposite the head of Owens River, and Mr. Palmer 
secured a specimen in the Sequoia National Park August 4’’. Dr. A. K. Fisher 
informs me (under date of December 4, 1907) that the specimen secured by Dr. 
Palmer is not now to be found, and he cannot recall having seen it himself; also
