U. S. P. E. R. EXP. AND SURVEYS-ZOOLOGY-GENERAL REPORT. 
A specimen from the Copper Mines (6404) differs in having the feathers of the back olive 
green, tipped occasionally with black. Instead of the one or two spots of white on the tips of 
the greater wing coverts there is a continuous band. The axillaries are olive green, instead of 
black. None of these differences, however, are inconsistent with a not quite mature specimen 
of the C. mexicanus.

Hab .—Coast of California. 
In this species the second quill is longest; the first intermediate between the third and fourth. 
The tail is quite deeply forked. There is a slight tendency to olive green in the middle of the 
hack. The yellowish green may he said to cover the whole wing coverts, although the black 
bases of the greater coverts are somewhat exposed ; the green on these passes into yellowish; 
their extreme tips grayish. The axillaries and under wing coverts are white. 
The young bird is like the female, with obscure blotches beneath ; the yellow margins of the 
wing coverts and secondaries brownish.
