EEVIBW OP AMERICAN BIEDS. 



[part I. 



uncertain. The bill is much like that of some Gerthiolx in shape 

 and curve, though the mouth is deeply cleft, and the tongue com- 

 paratively simple (see page 163), as in the Warblers. In the com- 

 pression, however, and decurvation of the bill, there is a close rela- 

 tionship to Ideria, though it is smaller, longer proportionally, and 

 much more slender. The basal joints of the middle toe are rather 

 more united than common in Sylvicolidae ; not so much as in Vireo. 

 The tarsi are shorter, and the claws more curved than in Icteria. 



This genus, confined to Cuba, is represented by two known species 

 which agree in having the upper parts olive gray, the crissum 

 whitish, the wings and tail not varied by white. The diagnosis is 

 as follows : — 



Head and neck all round yellow (slightly olivaceous above) ; 



rest of under parts whitish, tinged with ashy on the sides fernandinm. 



Head and neck above like the back ; sides of head (sharply 

 defined against the vertex) and whole under parts, except 

 crissum and anal region, bright yellow .... fornsii. 



Teretristis fernandinae.

 Hab. Western Cuba. 



Head and neck all round olive green above, yellow beneath ; the loral 

 region and eyelids, and edge of wings also yellow. Rest of upper parts ashy 

 gray, with faint tinge of olivaceous. Under parts pale ashy gray, lighter 

 across breast ; the middle of breast and belly yellowish-white. Lining of 

 wings white. Bill dark lead color, lighter along the tomia. Legs dark brown. 

 The bill varies a good deal in size and shape.
