Humming-birds from Bolivia. 489 



known, some considerable time in Bolivia some few years 

 ago. On his return to this country I became the fortunate 

 possessor of many of his specimens of Humming-birds ; but, 

 owing to the illness which has afflicted me for a considerable 

 time, I have not been able, till lately, to incorporate Mr. 

 Buckley's specimens in my collection of Trochilidae. Having 

 now been able to examine my series more closely, I have come 

 to the conclusion that two species, at least, are new to science, 

 and I place a description of these two birds at once before the 

 public. One is a new Gynanthus; but the other is a new form 

 so different that it must be generically separated. 



Cynanthus bolivianus, sp. n. 



Similar to G. mocoa from Ecuador, but much smaller and 

 of a brighter metallic green, and with the tail more of a bril- 

 liant steel-blue than a vivid green. Total length 6*3 inches, 

 culmen 0'7, wing 2"6, tail 4*1, tarsus 0*2. 



Hab. Bolivia. 



I possess several males of this new species, as well as of 

 the allied C. mocoa; so that it is not without ample material 

 before me that I describe the Bolivian bird as new to science. 

 C. mocoa measures 8 inches in length, and has a wing of 

 3 inches and a tail of 5*5 inches. 



Pinakoi^EMA*, gen. nov. 



The general appearance of this bird reminds one of Lam- 

 p&rnis ; but it has an extremely long wing. In the latter 

 respect it resembles Oreotrochilus ; but it differs from this 

 genus in its strongly curved and lengthened bill and in its 

 very broad tail-feathers, while its extremely small feet seem 

 peculiar to the genus. 



Pinarolmma Buckleyi, sp. n. 



Brown, with a purplish gloss on the back ; the upper tail- 

 coverts and tail-feathers brown, glossed with purple, and 

 having a subterminal band of steel-blue; under surface of 

 body brown, slightly washed with metallic green ; the throat 

 lighter brown, the feathers edged with paler brown, giving a 

 scaly appearance ; vent and under tail-coverts white, the 

 latter washed with brown. Total length 4*6 inches, culmen 

 1-05, wing 2-95, tail 1-85, tarsus 0'15. 



Hab. Misqui, Bolivia, 10,000 feet.
