584 U. S. P. R. R. EXP. AND SURVEYS ZOOLOGY GENERAL REPORT. 
CYANOCITTA, Strickland. 
Cyanocitta, Strickland, Annals and Mag. N. H. XV, 1845, 260. Type, Garrulus califomicus, Vigors. 
Jiphelocoma, Cabanis, Mus. Hein. 1851, 221. Same type. 
Ch. — Head without crest. Wings and tail blue, without any bands. Back with a gray patch, different from the head. Bill 
about as broad as high at the base, and the culmen a little shorter than the head . Nostrils large, nearly circular, and concealed. 
Tail shorter or nearly equal to the wings, lengthened, graduated. 
This genus has much the general character of Cyanura or the hlue jays, hut is readily- 
distinguished by the ahsence of a crest and of black bars on the wings and tail. The wings 
generally are shorter ; the general characteristics, however, appear much the same. 
The G. ultramarina differs from the other species in having the wings considerably longer, or 
fully equal to the tail, which also is nearly even, instead of considerably graduated. 
Synopsis of species. 
Blue of sides of head extending over the sides of the breast to its middle. Chin, throat, 
and breast white ; the feathers of the latter margined with blue. Interscapular gray patch 
conspicuously different from the head. A superciliary streak of white. 
Belly and under tail coverts dull white. Forehead blue. A well marked superciliary 
stripe G. californica. 
Belly light brownish ash ; under tail coverts blue. Forehead blue like the crown. 
Interscapular region glossed with blue. Superciliary stripe distinct G. tooodhouseii. 
Belly brownish ash; under tail coverts blue. Forehead and sides of crown bluish hoary, 
conspicuously different from the hlue crown, the superciliary stripe not well marked. 
G. fioridana. 
Under parts without any bluish edges to the pectoral feathers ; breast bluish ash ; belly and 
crissum pure white. Interscapular region scarcely different from the remaining upper surfaces. 
Tail nearly even, considerably shorter than the wing G. ultramarina. 
Tail rounded, nearly as long as the wings G. sordida.

Sp. Ch. — Width of bill at base of lower mandible rather more than half the length of culmen. Lateral tail feathers about 
an inch shortest. Tail an inch longer than the wings. General color above, including the surface of the wings, bright blue, 
without any bars. The whole back, including to some extent the interscapulars, brownish ash, very faintly glossed with blue 
in the adult. A streaked white superciliary line from a little anterior to the eye as far as the occiput. Sides of the head and 
neck blue, the region around and behind the eye, including lores and most of ear coverts, black. The blue of the sides of the 
neck extends across the fore part of the breast, forming a crescent, interrupted in the middle. The under parts anterior to the
