"A quite typical Laphyctes, with strongly forked tail and the character- 

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

 melaneholicus and L. satrapa, hence the smallest known species of the 

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

 clement of the vivid yolk-yellow crown, the darker back, appearing pe- 

 culiarly spotted, and the lighter sulphur-yellow. color of the under parts. 

 Unfortunately, the only specimen which has reached us is without any 

 indication of its habitat/'

"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 specimen are not 

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

 quite as much as in T. melaneholicus." 



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

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

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

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

 rounded, — quite an important question in this connection.
