12 Messrs. Salviu and Elliot on the Trochilidae. 



This fine species is easily recognized from its allies by having 

 the entire tail-feathers of a uniform glossy black. It appears 

 abundant in Ecuador. 



Our specimens are as follows : — 



Ecuador: two {ex Gould), Mus. D. G. E.; one {Fraser), 

 Mus. P. L. S. ; three {ex Gould), Mus. S. & G.; one {Buckley), 

 Mus. S.&G. 



11. Phaethornis guyi. 



Trochilus guyi, Less. Hist. Troch. p. 119, t. 44. 



Phaethornis guyi, Gray & Mitch. Gen. of Birds, i. p. 104, 

 sp. 6; Gould, Mon. Troch. pi. 26. 



Hab. Venezuela {Goering) ; Trinidad {Leotaud). 



This species, first described by Lesson in his ' Hist. Troch./ 

 differs from the others of this section in having the base of 

 the tail a bright glittering green. It is a native of Trinidad 

 and Venezuela, having been procured in the latter country by 

 Mr. A. Goering. 



We have examined the following examples : — 



Venezuela: one {Goering), Mus. S.&G. 



Trinidad : one {ex Gould), Mus. D. G. E. 



Trinidad : one, Mus. J. Gould; one, Mus. P. L. S. 



And others with localities of questionable authenticity. 

 + 12. Phaethornis emili^e. 



Trochilus emilice, Bourc. Ann. Soc. Sci.de Lyon (1846) , p. 31 7. 



Phaethornis emilia, Gould, Intr. Troch. p. 44. 



Hab. New Grenada {Bourcier) ; Veragua {Arce) ; Costa 

 Rica {Arce). 



This bird was described by M. Bourcier as distinct from 

 the P. guyi ; but Mr. Gould, in his article on that species, has 

 thrown reasonable doubts upon its specific value. From the 

 specimens before us we find that it is difficult, perhaps impos- 

 sible, to distinguish many Columbian examples from those 

 from Venezuela. The Central-American specimens are a little 

 more blue ; and though we doubt if ultimately the distinctness 

 of the two species can be maintained, yet for the present we 

 refrain from placing both forms under the same name*. 



* Since the above was in type Mr. H. Whitely has sent a specimen 

 undistinguishable from P. guyi from Eastern Peru. It may be that the
