1854.] 119 



Differs from C. stelleri in longer and narrower crest, the deeper black of the 

 head ; the feathers on the side of the forehead streaked with white, not green; 

 the white feathers over the eye ; more grey on the feathers of the chin at base ; 

 narrower bill, &c. 



100 miles west of Albuquerque, N. M. 



Carpodacus cassinii, Baird. 



Bill very stout and much elongated, straight or even concave for four-fifths its 

 length, then gently curved. Wings lengthened ; 2d and 3d quills nearly equal 

 and longest. 1st intermediate between the 3d and 4th. Tail moderately broad; 

 quite deeply emarginate ; inner feathers nearly the one fourth of an inch shorter 

 than the outer. 



Male. Whole upper part of the head from the bill to the neck of a rich deep 

 crimson ; sides of the head below the eyes, chin, throat and upper part of the 

 breast pale purplish. Feathers on the lower part of the hind neck, back, and 

 scapulars gray, and with a dark brown central streak, and glossed all over with 

 purplish. Breast, abdomen, belly, and crissum uniform w T hite, anteriorly tinged 

 with purplish gray, laterally streaked with brown ; under tail coverts white, 

 similarly streaked. Lower part of the back and rump faintly purplish. Quills 

 and rectrices brown ; all margined with dull purplish. Secondary and tertiary 

 quills and primary coverts more broadly margined. Lesser coverts strongly 

 glossed with purple. 



The female is larger than that of C. obscurus ; wings longer ; belly immaculate, 

 streaked only on the sides. 



Male. Total length 6i inches, wing 3 7-12ths, tail 2 10-I2ths, tarsus 7 |-12ths, 

 bill on ridge 6 -12ths. 



This very strongly marked species may be distinguished by the very long and 

 nearly straight bill w r hich is larger than in any other N. American species. The 

 crimson of the head extends to the cervix as in C. purpureus ; the back is con- 

 spicuously streaked ; the lower parts white and streaked only laterally ; the 

 reverse being the case in C '. familiaris . It resembles C. purpureus most, but is 

 larger, bill, wings and tail longer, with less purple on the breast, &c. 



Camp 104, Pueblo Creek, N. M., and 75 miles west of Albuquerque. 



This species is named in honor of Mr. John Cassin, of the Academy of Natu- 

 ral Sciences of Philadelphia. 



Zonotrichia fallax, Baird. 



This species bears a very close resemblance to Z. melodia, of which it is the 

 western representative. Compared with Z. melodia the bill is considerably 

 smaller and the tail longer. The plumage above is more ashy, the streaks on 

 the back not so distinct, the spots are more crowded about the breast, but fewer 

 on the sides ; their color more uniformly chesnut brown. 



Length 6i inches, wing 2 8-l0ths, tail 3. 



Pueblo creek, New Mexico. 



Pipilo mesoleucus, Baird. 



Bill considerably curved and inflexed at edges. Tarsi short, outer claw reaching 

 a little beyond the base of the middle claw. Above nearly uniform dull olive 

 brown, except a patch of dark chestnut on the top of the head; chin, throat and 

 upper part of the breast pale reddish white, streaked on the border of the area 

 with brown ; and below this there is a central large spot, formed by the adja- 

 cent brown inner vanes of several feathers. This spot is below the collar of 

 smaller ones just described. Middle of the breast and abdomen white. Lower 

 part of the belly, crissum, and under tail coverts light ferruginous. Sides like 

 the back with a slight tinge of rufous. Wings and tail like the back, the latter 

 with rusty tips. 



Total length 81 inches, wing 3 ll-12ths, tail 4 7-12ths, tarsus 5-12ths. 



Differs from P. fusca, (which appears to be confined to the Pacific coast,) in 

 a more distinct patch of chestnut on the crown, not merely tinged with this 

 color; lighter throat, the rusty color extending further down, as do the attend-
