interruption along the shaft. On the scapulars, axillars, and other elongated feathers there are several white bars. The 
facial disk is grayish, obscurely barred with brown ; the posterior margin of the ear is uniform liver brown, then becoming 
banded with white. The longest quills and tail feathers show about 7 to 9 clouded transverse light bars, one of these at the 
end of the feather ; the bars on the inner and outer margins are quite white, especially towards the base of the feather, 
elsewhere they are mottled yellowish brown or brownish yellow ; the legs are dirty yellowish, with obscure and rather trans- 
verse mottlings of brown. The bill is greenish j 7 ellow ; the iris gamboge; the claws horn color; the toes are thickly 
feathered to within two scutella} of the base of the claws. The fourth quill is longest, the fifth and then the third a little 
shorter, the second between the sixth and seventh ; the first rather shorter than the eighth. 
Length of male 18 inches ; extent 40 ; -wing 13 ; tail 8£ ; tarsus about 2. 
This species, with a general resemblance to the Syrnium nehulosum, is of rather smaller size, and readily distinguished by 
the entire absence of any of the longitudinal brown stripes so conspicuous on the belly, flanks, and lower tail coverts of the 
latter species ; these regions being barred transversely with white and brown. The white bars on the feathers are much less 
continuous and regular, and on the neck and head are restricted to rounded spots instead of forming regular zones. The 
under wing coverts are banded transversely instead of being uniform yellowish white The bill is less pure yellow. 
A single specimen (original number 1858) was collected at Fort Tejon, March 6, 1858.
