JEupherusa. It was then separated as a subgenus under the title ClotJio, which being 

 used elsewhere in zoology, was supplanted by Callipharus by Mr. Elliot in 1879. 



The position assigned to the genus has always been near HupJieirusa ; and this we 

 think correct, for the structure of the bill is similar as well as other points of resem- 

 blance. 



From Microchera it differs in having the crown black and the nasal covers partly 

 exposed. 



The distribution of the genus is that of the single species which follows.

Mr. Lawrence's type of this species formed part of a small collection of birds made 

 in Costa Rica by the botanical traveller A. R. Endres ^, and sent by him to the United 

 States National Museum. Other specimens reached this country from the same source, 

 and also from the well-known collector Julian Carmiol. In the higher parts of the 

 State of Panama this bird is also found, as Arce sent us a good series of specimens, 

 including adults of both sexes and young males, from the Cordillera del Chucu and 

 other places in the same district. 



In young males the feathers of the mature plumage begin to appear in the middle 

 of the under surface, and gradually spread to the sides, and lastly cover the crown.
