 depth at base .o4-.40, widtli .58-.C0 ; tarsus, .70; middle toe, .58-.G2 

 Adult : Above nniform clear plumbeous, tbe auriculars darker (nearly 

 black); feathers of the pileum with blackish shaft-streaks, and pure 

 white at the base ; a concealed patch of bright orange-red. AYings and 

 tail blackish slate, the larger wing-coverts and secondaries edged with 

 whitish gray ; rectrices faintly paler along edges and at extreme tips. 

 Lower parts white, shaded across the breast with pale ash-gray, the 

 sides of the breast strongly of this color; lining of the wing white, the 

 axillars (in some siiecimens) tinged with sulphur-yellow. 



Hab. — ISTorthern coast of South America and the Lesser Antilles. 



Eemakks. — This bird so closely resembles T. ilommicensis in color and 

 form as to suggest the probability of its being a local race of that spe- 

 cies. It is proper to state, however, that I have never seen an interme- 

 diate specimen, though many of both species have been examined, and 

 the slight difference in coloration (noted under the head of T. domini- 

 censis and in the synoptical table), as well as the quite marked difference 

 in size, may be found entirely constant.
