420 U. S. p. R. R EXP. AND SURVEYS — ZOOLOGY — GENERAL REPORT. 



In the preceding diagnosis I have described a specimen from Mr. Audubon's cabinet, and 

 probably one of those mentioned by him as having been obtained at Henderson, Kentucky. 

 There is no authentic instance on record of its having been obtained elsewhere in the United 

 States. Its black head will readily distinguish it from the other species. The first and second 

 quills are equal and longest ; the third very little shorter. 



The C. notatus of Dubus diflers in having a slender and more attenuated bill, the black of the 

 throat coming further on the breast. The wing coverts entirely black, excepting a band of 

 yellowish on the tips of the greater ones, and the secondaries without any yellowish edging. 



Lht of specimens. 



CHKYSOMITRIS STANLEYI, Bonap. 



Stanley's Goldfinch. 



Carduelis stanleyi, Add. Synop. 1839, 118.— Ib. Bircis Am. Ill, 1841, 137 ; pi. 185. (Not given in Cm. Biog.) 

 Chrysomitris stanletji, Bf. Consp. 1650, 515. 

 Hypacantkus stanleyi, Cab. Mus. Hein. 1851, 161. 



Sp. Ch. — Above, with scapulars and ends of lesser wing coverts dark olive green, brightening on the rump ; the feathers of 

 the back obscurely streaked with brown. Posterior upper tail coverts dusky. Crown and chin black. Forehead, sides of 

 head, under parts generally and sides, greenish yellow, turning to white posteriorly. Wings and tail dark brown ; the tail 

 feathers, excepting the central, yellow at the base, as are the quills, excepting the first two primaries and the inner tertiaries. 

 The edges and tips of the greater coverts are also yellowish. 



Female without the black on head and throat. Length of male, 5.75 ; wing, 2.80 ; tail, 2.20. 



Hob. — California, (?) probably western Mexico. 



This species is so similar in all essential features to the G. magellanicus as almost to indicate 

 that it is only an immature stage of plumage. The crown and chin only are black, instead of 

 the entire head all round ; the black of the chin, however, is edged with yellowish, and there 

 are indications of black on the sides of the head near the bill, showing an immature condition. 

 The upper parts are similar in their shade of green ; the rump is not nearly so bright yellow, 

 and the longer upper tail coverts are not yellow but brown. The middle of belly and thence to 

 the tail coverts are whitish, the latter streaked with brown instead of uniform unspotted yellow. 

 The markings on the wing are very similar, except that the bases of the first two primaries are 

 not marked with yellow as they are in the other, excepting on the outer web of the first. The 

 middle tail featlier appears to be brown to the very base instead of yellow. 



The feet are, liowever, much larger ; the toes longer. The bill is larger and more curved 

 above. The proportions of the two quills are much the same. 



The pair I here describe arc from Mr. Audubon's collection. The draggled appearance of tlie 

 win"s and tall appear to indicate that they had at one time been kept alive in a cage. 



This species has somewhat the appearance of Ch. psaltria, but is much larger ; has a black 

 chin ; the quills and tail with yellow instead of white markings, &c.
