CYNANTHUS GRISEIVENTRIS, Tac. 



Grey-bellied Train-bearer. 



Cynanthus griseiventris, Tacz. Proc. Zool. Soc. 1883, p. 72. 



Dr. Taczanowski has received this species from Paucal in Peru, where it was collected by Mr. Jelski. The 

 original specimen was not quite adult, and had the tail somewhat damaged. 



The following is a translation of Dr. Taczanowski's description : — 



Above green, with the forehead scaly for a long distance and very brilliant ; underneath entirely pale 

 ashy grey ; the throat bright blue ; the feathers white at the base ; vent white ; wing-coverts uniform with 

 the back, the edge of the wing white; first primary externally margined with white; tail deeply forked, 

 brilliant green, the centre tail-feathers having a very broad apical lustre of reddish copper ; outer tail- 

 feathers blue-black, ending in green ; tail bluish green below. Bill black ; feet blackish.

CYNANTHUS CCELESTIS, Gould. 



Ecuador Train-bearer. 



Cynanthus ccelestis^ Gould, Intr. Trochil. p. 102 (1861).

This Ecuador Train-bearer is "considerably larger than the C. cyanurus; it also presents a marked 

 difference in the colouring of the under surface, which is uniform coppery brown instead of green ; in other 

 respects the colouring is very similar to the specimens from Bogota, with green and blue tails. In no 

 instance have I seen a specimen from Ecuador with an entirely blue tail, whereas they frequently occur 

 among those sent from Bogota." (Gould, /. c.) 



Mr. D. G. Elliot, in his 'Synopsis' (p, 152), does not admit the distinctness of the present bird from 

 Colombian examples, and considers that Mr. Gould's species was established on too slight grounds to be 

 maintained. Count Von Berlepsch and Dr. Taczanowski, however, admit a certain amount of difference 



in the Ecuador bird.
