" This Humming-Bird seems to have been quite unknown at Coban previously to the collection of my speci- 

 mens. The first was shot by my collector, Cipriano Prado, among some Salvice, in one of the mountain hollows near 

 Coban. Salvice being in flower in November, their blossoms are sought after by nearly every species of Hummino-- 

 Bird near Coban, and this among the rest. It is rare even at Coban ; and though much sought for by the Indian 

 boys in consequence of my offers of reward, but few specimens were obtained. 



"Three males to one female appears to be about the proportion of the sexes/' — Salvin in Ibis, vol. ii. p. 261. 



There is no one genus among the Trochilid?e that has more sadly puzzled me, and doubtless other ornitholo- 

 gists, than that containing the two species known under the specific names of virescens and viridissimus QChrysobron- 

 chiis virescens and C. viridicaudus of my Plates j, no two persons agreeing as to the place they should fill in the family.
