Sp. Ch. — Wing much rounded ; the second quill shorter than the secondaries. Tail much graduated. Bill much decurved, 

 jonger than the head. Above brownish olive, without any shade of green •, beneath pale cinnamon, lightest on the throat, 

 deepening gradually into a brownish rufous on the under tail coverts. The fore part of the breast and sides of the body brown 

 olive, lighter than the back. An obscure ashy superciliary stripe, and another lighter beneath the eye. Ear coverts and an 

 indistinct maxillary stripe dark brown ; the shafts of the former whitish. Ends and tips of tail feathers obsoletely paler. 

 Length, 11.50 inches ; wing, 4.20 ; tail, 5.75 ; tarsus, 1.55. 



Haft. — Coast of California. 



The curvature of the hill of this species is very great, the chord of the lower jaw measuring 

 1.65 inches; the ordinate is .25 of an inch. The outer tail feathers are about 1.30 inches 

 shorter than the middle. There is no line of demarkation between the colors of the belly and 

 under tail coverts. There is a slight rufous tinge on the upper tail coverts and outer margins 

 of the tail feathers, which are darker than the back, with, perhaps, a faint purplish tinge. 

 The outer webs and tips of the tail feathers are lighter brown than the remaining portion, 

 though the difference is scarcely appreciable. There are no spots on the breast, but cinnamon 

 edgings to some of the brown feathers on the breast impart a waved appearance. 



A specimen (4902) from San Diego, California, has a more rufous tinge in the upper parts. 

 There is a faint indication of paler edges to the tertial and wing coverts, forming bands, but 

 this may be merely an immature condition. 



In the entire series the differences in length of the bills amount to as much as half an inch. 

 * Young birds differ only in a duller plumage. The under parts do not exhibit any indications 

 of spots.
