Carpodacus cassinli, Bairu, Pr. Ac. Nat. Sc. Pliila. VII, .Tune, 1854, 119. Colorado River. 



Sp_ Ch. Larger than C. jm)-p«reus. Bill .55 of an inch above. Second and tljird f|uills longest ; first longer than fourth. 



Above pale grayish brown, the feathers streaked with darker brown, and witli only an occasional gloss of reddish, e.xcept on 

 the crown, which is uniform deep crimson, and on the rump. Sides of tlie head and nock, tliroat and upper part of breast with 

 ruTip, pale rose color ; rest of under parts white, very faintly and sparsely streaked with brown. Female without any rod, 

 and streaked on the head and under parts with brown. Length, G.50 ; wing, 3. GO ; tail, 2.60. 



IJab. — Rocky mountains and valley of the Colorado. 



This i.s the largest of the American purple finches, and is conspicuously dificrent from the 

 others in the size and unusual elongation of the bill. This is very nearly straight above to 

 within one-third or fourth of the end, and then curves gently to the tip ; the cutting edge of 

 the mandible is sinuated in the middle. Tlie proportions of the quills, as given above, are 

 pretty constant, although sometimes the second quill is longest, and sometimes the first as long 

 as the second. The tail is moderately forked ; the feathers broad. 



There is rather more of red on the nape than on the back, where this color is only occasionally 

 visible. The rose of the breast is not abruptly defined, but passes gradually into tlie white of 

 the belly. 



This species is more like C. purpureus than the other North American purple finches, but is 

 larger and otherwise easily distinguished. The bill is much larger, and longer proportionally. 

 The pro])ortions of the quills are difTerent; the tail less deeply forked, and tlie feathers broader. 

 Tlie crimson of the head is brigbtor ; lliere is much less rod on the back, although the crown and 

 rump patches are not abruptly defined. The streaks on tlie back are darker and more conspic-
