•'A quite typical Laphycte.s^ with strongly forked tail and the character- 

 istic tapering to the points of the five outer primaries; smaller than L. 

 nielanchoUcu^ and L. mtrapa^ hence the smallest known species of the 

 genus. Distinguished by the weaker and shorter beak, the dark encir- 

 clement of the vivid yolk-yello^\- crown, tlie darker back, appearing jie- 

 cuharly spotted, and the ligliter sulpbur-yellow color of the wider parts. 

 Unfortunately, tlie only .si)ecini('n whicli lias reached us is without any 

 indication of its habitat."

" One ex. '' Irides hazel : bill and legs black.'' 



"A species of true Tyrannus, looking to its general structure and acu- 

 minated primaries, distinguishable by its small size, pure white throat 

 and neck, and black tail. The primaries of the single si)ecimen are not 

 fully developed; but the three first are somewhat obtusely acuminated, 

 quite as much as in T. melancholieus.'' 



Eemaeks. — From the description above quoted, this species would 

 appear to resemble somewhat the T. vcrticalis of North America; but 

 whether such are its real afiinities, its describer does not explain. 

 The description does not .state whether the tail is even, emarginated, or 

 rounded. — quitv an importaut question in this eonuection.
