" Tyrannus magnirostris," Scl., Catal. 1861, 263, No. 1449 (nec D'Orb.).' 



Sr. Oh.— Wings, 4.70-4.75; tail, 3.85-4.20; bill, from nostril, .02-.95 

 depth at base .34-.40, width .58-.60; tarsus, .70; middle toe, .58-.02 

 Adult: Above uniform clear plumbeous, the auriculars darker (nearly 

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

 white at the base ; a concealed patch of bright orange-red. Wings 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 specimens) tinged with sulphur-yellow. 



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



Remarks. — This bird so closely resembles T. dominicensis 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.
