MiCROTROGON NEW GENERIC NAME 95 



beak, near its base, is strong-ly angular. (*) rising into a 

 ridge, and not the arch of a circle, as generally in ali other 

 New-world Trogonidae. Moreover the original describer Des 

 Murs has already called attention to this really salient fea- 

 ture. 



I propose to raise the Trogon ramonianus Des Murs 

 to the degree of a new genus, to be called Microtrogon, 

 a term which appears to me very acceptable as being very 

 significant of one of the striking features. 



June — November 1905. 



( * ) It is true that a tendency to the formation of a median ridije 

 is perceptible also in some individuais of certain other species, as it seenis 

 especially of male sex, for example in a young male of Trogon atricollis 

 and in a male of T. viridis of our collection. But it never manifests itself 

 so sharply pronoiínced as in the T. ramonianus, where it becomes a rule.
