of this species is the island of San Lucas in the Gulf of Nicoya, where Don A. Alfaro 

 and Mr, Cherrie met with it ^. 



T. elegans most resembles T. ambiguus, but may readily be distinguished in the 

 adult dress by the more distinct banding of the outer tail-feathers and the coarser 

 freckling of the wing-coverts. T. ambiguus, as will be seen below, has a much more 

 northern range, and the two birds are not found together so far as we know.

Gould described this species in 18-85 ^ defining its differences from T. elegans as 

 consisting of the outer rectrices being obscurely and finely dotted, instead of beino- 

 marked with strong well-defined bars. In his ' Monograph of the Trogonidse ' he further 

 drew attention to the finer freckling of the wing-coverts and the deeper bronze colour 

 of the upper surface, particularly of the central rectrices. Many specimens have 

 reached us, and these characteristic features of T. ambiguus have been abundantly 

 confirmed. 



The range of this species seems quite distinct from that of T. elegans, and is much 

 more northerly, extending on both sides of the Mexican highlands to the State of
