U. S. P. R. R. EXP AND SURVEYS — ZOOLOGY—GENERAL REPORT 
specimens have common characters in which they differ from California jays. The most 
striking of these differences is in the much darker shade of the under parts, in which there is no 
white at all, except perhaps immediately around the anus. The under tail coverts are of a clear 
blue, almost as bright as that on the upper coverts, and there is a general faint gloss of blue 
beneath, especially along the middle of the body, while in cali/ornica there is only a faint trace of 
blue on the under coverts. The back is more strongly glossed with blue ; so much so as almost 
to take away the impression of any gray patch at all. The lores are quite black, without the 
mixture of hoary, seen in cali/ornica. The wing is rather longer in proportion ; the tail rather 
less graduated. The bill is more slender. 
A specimen, 8465, from Mexico, doubtfully referred here, is quite similar to those from the 
Rocky mountains ; the tail is, however, rather less graduated, and the under tail coverts are 
white. There is little or no trace of the superciliary line of white spots. The bill is much 
shorter, broader, and more obtuse.

Sp. Ch. — Tail much graduated ; lateral feathers more than one inch shortest. Tail an inch longer than the wings. Above 
blue ; middle of the back brownish ash. Forehead and sides of the crown, including the nasal feathers, hoary white. Sides 
of head and neck, blue ; the former tinged with blackish, the latter sending a streaked collar of the same across the breast; 
region anterior to this collar dirty white streaked on the edges of the feathers with blue ; rest of under parts dirty whitish 
brown ; under tail coverts blue, the tibia tinged with the same. Length, 10.50 ; wing, 4.40 ; tail, 5.70 ; tarsus, 1.45. 
This species is very similar to the Rocky mountain C. looodhouseii in the color of the under 
parts, including the brown belly, the blue crissum, the pectoral band, &c. The back, however, 
is much lighter and better defined grey, more so even than in O . cali/ornica. It differs from 
both species in the hoary on the forehead and sides of the crown, and in the absence of the 
superciliary line of white spots, as also in being considerably smaller.
