Hab. Columbia. 



A native of Columbia, this species appears to be quite 

 common in the vicinity of Bogota, whence numerous ex- 

 amples come to Europe. It is the most brilliant species of 

 the genus, and is closely allied to C. cyanocephala, from 

 which it differs chiefly in the white under tail-coverts, and 

 in the greater brilliancy of the sides of the neck and flanks. 



Cyanomyia cyaneicollis.

Hah. Peru, eastern slope of the Andes iJVarszewiez) . 



I only know this form by the two specimens in Mr. Gould's 

 collection. It is certainly very closely allied to C. francice, 

 with the blue of the crown extending further down on the 

 nape than in specimens of that species ; but before being able 

 to come to a satisfactory decision as to its specific value it 

 is desirable to see more specimens. 



Peru is further south than any of the other members of 

 this genus are known to pass ; and it is not improbable that 

 a different species exists in that countr\^ The type sjje- 

 cimens were brought by M. Warszewiez; and although Peru 

 has been fairl}^ explored by several good collectors since his 

 time, the bird has not again been met with.
