CATHARUS. 



third of that of the 2d qiiill, instead of nearly or quite one-half. The 

 bill is shorter and more slender (.3(3 or less from tip to nostril, instead 

 of .42). The tarsi and toes are absolutely and relatively about the 

 same length as in melpomene (tarsus 1.25, middle toe and claw .85 

 in No. 22,361 ; a little less in 29,202). 



It will be seen from the specimens indicated as from Orizaba, that 

 this species is not confined to the west coast, as supposed.

 olive, a little more rufous on the rump and tail, still more so on the 

 head above and nape ; the outer edge of primaries a little grayer 

 than the back. Beneath plumbeous gray, darkest on the front and 

 sides of the breast, under wing covers, and thighs. Edges of throat

Another specimen (No. 30,483), although quite different, appears 

 to be a more immature stage of the same species. The upper parts 

 are darker and tinged with a more brownish rufous ; the breast and 

 sides are also strongly marked with the same. 



The Catharus frantzii is intermediate between G. melpomene and 

 occidentalis. The back is more olivaceous and darker than in the 

 latter, the head of much the same color. Different from either, the 

 outer webs of the primaries are grayer than the back, instead of
