GENEBA AND SPECIES. 209 



Bonaparte, we may mention Trochilus cristatus, 

 Linn., in which the crest is golden-green, blue at 

 the tip. 



Locality- : Martinique, Trinidad. In Gould's 

 cabinet. 



Trochilus chlorolophus, Bonap. This species 

 is less than the former, and its crest is altogether 

 of a golden-green. 



Locality : Martinique. In Gould's cabinet. 



Genus CEPHALEPIS, Loddiges, (Orthorhynchus, 

 in part, Cuvier; Mellisuya, in part, Gray). 



This genus is so closely allied to Orthorhyn- 

 chus, both in the form of the beak and of the 

 beautiful crest, that we hardly know on what 

 definite grounds it is separated ; the more es- 

 pecially as Mr. Loddiges has not, so far as we 

 are able to ascertain, given any precise charac- 

 teristics. Referring to the Proceeds. Zool. Soc. 

 December, 1830, we find the following passage : 

 "Mr. Vigors exhibited several species of 

 Humming-birds, from the collection of Mr. John 

 Gould; one of which, previously undescribed, 

 had been dedicated to Mr. George Loddiges, 

 1\L.S." &c. It approaches most nearly to the 

 Trochilus Lalandei, Vieillot, but may be dis- 

 tinguished from that bird (in which the crest 

 is brilliantly green, and the throat and breast 

 rich blue) by the following characters. 



Trochilvs Loddigesii, Gould. Crest elon- 

 : gated, and of a purple lilac; throat and upper
