Roraima (5000-6000 ft.) {Schomburgk ; Whitely). 



Mr. Whitely obtained a good series of this species, which 

 does not seem to have been met with since Schomburgk's 

 expedition. Mr. Sharpe (Cat. B. Brit. Mus. vi. p. 258) has 

 applied this name to the Guiana form of the next species ; 

 but the specimens we now possess show that this view is 

 quite erroneous. The present species is quite distinct and 

 has no near allies, unless it be the island forms T. marti- 

 nicensis &c.
