Habitai : Venezuela circuni Caracas. 



Typus : in Mus. H. v. B. : J "Antimano near Caracas, 12th 

 February, 1890." [C. Peters leg.] 



The single specimen of this species, collected near Caracas 

 by Mr. Carl Peters, and which I have named after him, is 

 evidently quite distinct from all the other species of Tyran- 

 iiiscus which are known to us. It seems to have its nearest 

 ally in T. vii issi mus (Sci. et Salv.) of Guatemala, but is 

 quite distinct in having the cap olivaceous-brown instead 

 of greyish-brown ; in the form and coloration of the 

 superciliary stripe which is narrower and more yellowish- 

 white, not pure white ; in the sides of the head being- 

 blackish instead of olivaceous-green, and also in the back 

 being of darker green. The breast is more greenish-grey, 

 not pure grey, and not so flammulated with j^ellowish. The 

 sides of the vent are more yellowish, less greenish, and the 

 wings are longer. 



It need hardly be compared with T. im/próbus Sci. et 

 Salv., from Menda, which has yellow underparts, a rather 

 more brownish cap, more yellowish superciliaries, and much 

 more distinct yellow margins to the upper wing-coverts.
