with renewal of the fifth, ninth, and tenth in one win<»- and the sixth 

 and eighth in the other. The second specimen has molted the second 

 primary in either wing. 



The species does not seem to have been recorded previously from 

 Uruguay. 



COCCYZUS AMERICANUS AMERICANUS (Linnaeus)

 (Carolina.) 



On February 15, 1921, an adult female Avas taken near Rio Negro, 

 Uruguay, as it worked slowly and silently through willows in an 

 open thicket along a small stream, in the same type of country as 

 that frequented by the black-billed C. melacoryphus. The specimen 

 is completing the molt and has the last of the new contour feathers 

 appearing on head and breast. The fifth, eighth, and tenth pri- 

 maries are not yet fully developed, though all of the old feathers in. 

 the wing (and also in the tail) have been cast. As this bird is in 

 molt, measurements of wing and tail are not reliable. The culmen 

 equals 26.2 mm. ; the tarsus, 26.5 mm. The coloration of the dorsal 

 surface is the same as that in early spring migrants of C. a. ameri- 

 canus when they arrive in the United States, and the inner webs of 

 the primaries are distinctly rufescent, not buffy as in C. a julieni 

 (Lawrence). The yellow-billed cuckoo has not been recorded pre- 

 viously from Uruguay, but the present record is not surprising, as 

 the bird has been noted from Buenos Aires.

AMAZONA AESTIVA (Linnaeus) 



Psittacus aestivus Linnaeus, Syst. Nat., eel. 10, vol. 1, 1758, p. 101. (South- 

 ern Brazil.) ^3 



An adult male taken at Kilometer 80, Puerto Pinasco, Paraguay, 

 has the shoulder partly red and partly yellow. As comparative ma- 

 terial is not available the subspecific identity of this specimen is 

 uncertain though on geographic grounds it may be supposed to 

 represent A. a. xantliofteryx of Berlepsch.^^ 



At Kilometer 80, west of Puerto Pinasco, Paraguay, these amazons 

 were common from September 7 to 21, and a male was taken Sep- 

 tember 7. On September 23 a few were observed farther west at 

 Kilometer 110, These parrots, called filli' puV by the Anguete In- 

 dians, were found in pairs, usually in groves of palms where they
