1915 HYPOTHETICAL LIST 185 
that Mr. Nelson thinks he might have been mistaken in the identity of the hum- 
' mingbirds seen opposite the head of Owens River. 
(3) Male taken at Oakland May 8, 1890 (McGregor, Auk, x1v, 1897, p. 91). 
This specimen proved to be a probable hybrid between Selasphorus rufus and 
Stellula calliope (Thayer and Bangs, Auk, xxiv, 1907, p. 313). 
It thus appears that Sclasphorus platycercus has yet to be satisfactorily 
identified within the state. It is a species belonging to the Rocky Mountain 
region of the United States, and has been found west to western Nevada. 
42 (442) Muscivora tyrannus (Linnaeus) 
Fork-TAILED FLYCATCHER 
Synonym—Milvulus tyrannus. 
Status—Toppan (Orn. & Ool., 1x, 1884, p. 48) states: ‘‘I have lately re- 
ceived from a dealer in California curiosities at Santa Monica, Cal., a fine speci- 
men of the Fork-tailed Flycatcher, (Milvulus tyrannus,) which was shot near 
that place in the latter part of the Summer of 1883’’. The circumstances of cap- 
ture are not definitely attested. Mr. Toppan writes me under date of April 18, 
1912, that the specimen in question was destroyed by fire in 1896. The species 
belongs to Tropical America, from southern Mexico southward, but has occurred 
casually in the eastern United States. 
43° (——) Calocitta colliei ( Vigors) 
COLLIE MAGPIE-JAY 
Synonym—Pica bullock. 
Status—‘‘ Woody portions of North California’’ (Audubon, Synopsis, 1839, 
p. 153). No doubt an inferential blunder based upon a bird mislabelled as from 
the ‘Columbia River’’. The species belongs to western Mexico. 
44 (__) Calocitta formosa formosa (Swainson) 
Buttock MaGpPIE-JAY 
Status—A specimen is in the collection of the Academy of Natural Sciences 
of Philadelphia labelled ‘‘California’’ (Stone, Proce. Acad. Nat. Sci. Phila., 1891, 
p. 442). ‘‘No doubt an error’’. The species is native to southwestern Mexico. 
45 (—_—_) Psilorhinus morio morio (Wagler) 
Brown JAY 
Synonym—Corvus morio. 
Status—A specimen stated to have been obtained at ‘‘San Francisco, Cali- 
fornia’’ (Eydoux and Gervais, Voyage of the Favorite, v, 1839, p. 54). A speci- 
men is listed by Baird (Pac. R. R. Rep., 1x, 1858, p. 592) as from ‘‘San Diego, 
Cal’’. Both records are extremely doubtful. The species is native to northeast- 
ern Mexico. 
46 (—_) Cissilopha beecheii (Vigors) 
BrECHEY JAY 
Synonyms—Pica beecheti; Cyanocitta beecheyi; Cyanurus beechen; Cyano- 
corax geoffroyt.
