352 KOIITII AMERICAN BIRDS. 



Olive-pliimbcous above ; beneath dingy white (not inter- 

 rupted on the breast) ; tinged posteriorly with sulphury (not 

 ochrey) yellow ; winff-bands pale ash. Wing, 2.80 ; tail, 2.G.5 ; 

 oulmen, .79 ; tarsus, .03. Hab. Bahamas. . var. bahamensis .' 

 C. First quill much longer than fifth (sometimes equal to fourth). Tail much 

 shorter than the wing. Bill much smaller, less depressed, and more triangular; 

 rictal bristles about one half the bill. 



5. C. virens. Colors of caribcnts var. bahamensis, but rather more 

 olivaceous above, and more distinctly tinged with sulphur-yellow pos- 

 teriorly beneath. Lining of the wings, and axillars, without any 

 ochraceous tinge; lower tail-coverts distinctly grayish centrally. 



Whitish of the lower parts not interrupted on the breast. Wing, 

 3.40; tail, 2.90; culmen, .67; tarsus, .54. Hab. Eastern Province 

 of United States ........ var. virens. 



Whitish of medial lower parts intt'rru])t(;d by a grayish wash 

 across the breast. Wing, 3.40; tail, 2.65 to 2.70 ; culmen, .70; 

 tarsus, .54 to 56. Hab. Western Province of United States, south 

 throughout Middle America to Ecuador . . var. richardsoni.^ 



1 Contopus (cnribceiis var. ?) haliamcnsls, Bkyant. Emjndonax bahamcnsis, Bkyaxt, List of 

 Birds of the Baliainas, 1859, p. 7. Young with the colors more asliy above, and less yellowish 

 beneath ; the upper parts with feathers faintly tijjped with paler, causing an obsolete transverse 

 mottling ; two distinct bands on wing of pale ochraceous. 



Of the above, caribiviis, hispanioUnsis, and pallidum are clearly to be referred to one species ; 

 the C. baJiamensis also has many chai'actei-s in common with them, and no violence would be 

 done by refemng it, also, to the same tj'pe ; it is, however, more modified from the standard 

 than any of the others, though the modifications are not of importance. 



^ These measurements are not only those of United States and Mexican examples, but also of 

 llidiUe American examples {" sordidulit.s," ScLATER, and "plcbcius," Cabanis), and of a series 

 hum Ecuador and New Granada {^= " bogotcnsi.%" Sclatek). In comparing a quite largi? 

 numliiT of such Middle American and Equatorial specimens with the large series of Xorthern 

 exami>les, we have been utterly unable to appreciate even the slighti'st ditl'erence between them. 



The C. ptincnsis (Lawp.. Ann. N. Y. Lye. IX, 1869, 237 ; Puna Island, Gua\-aquil) is founded 

 upon an immature specimen, so the characters of the species cannot be given with exactness. 

 The relationship ajipears very close to the C. caribams, there being the same large, very depressed 

 bill, with the long bristles reaching nearly to its tip, and the tail abont as long as tlie wing ; 

 while the upper plumage has the light faint transveree mottling seen in the young caribceus, var. 

 haluimensis, and the lining of the wing ochraceous. In colors, however, the two are very differ- 

 ent, the young of 2>uncnsis being ashy-green, instead of pure ash, on the back, the crown very 

 much darker, instead of not appreciably so ; the wing-bands are wliite instead of ochraceous, 

 while the bi-east and sides are dull sulphur-yellowish, instead of ashy, without any yellow tinge. 

 The measurements are as follows : AVing, 2.60 ; tail, 2.60 ; culmen, .72 ; tarsus, .56. 



The C. ochraceiis, ScLATEU & Salvin (P. 7.. S. 1869, 419 ; Salv. Ibis, 1870, 115), of Costa 

 Rica, we have not seen. From the description, however, it seems to be scarcely ditferent from 

 C. lugubris, and it is probably the same. The si^e (wing, 3.30) appears to be a little smaller, 

 and the belly more deeply yellowish.
