This bird differs somewhat in form from the two preceding species, and it may be found necessary to institute 

 a separate genus for its reception. It is a very rare bird, and the two specimens, male and female, in the collection 

 at the Jardin des Plantes at Paris are the only ones I have ever seen. 



The little glittering-green Humming-Birds forming the genera Chlorolampis, Chloristilbon and Panychlora, are 

 very widely spread over the temperate and warmer parts of the South American continent, being found along the 

 whole course of the great Andean range, from Mexico on the north to Bolivia on the south ; they also inhabit 

 Brazil, Cayenne, the Guianas, Trinidad, and Venezuela. The sexes differ very considerably in colour in nearly 

 every species,— the males being clothed in a metalHc covering, while that of the females is soft in texture and sombre 

 in hue. 



The members of the 



Genus Chlorolampis, Cab,, 



as restricted by me, are distinguished for their deeply forked tails, most of the feathers of which are singularly 

 tipped with dull grey. They range over a great part of Mexico, Guatemala, Costa Rica, Veragua, and Panama, 

 where they apparently terminate, as I have never received examples from any part southward of the isthmus. The 

 finest species of the genus is the C. auriceps, a bird of very elegant form, and having a deeply forked tail ; most 

 nearly allied to this is the C. Caniveti : both these birds are from Mexico. Following these is the little bird I have 

 named C. Osberti, after Mr. Osbert Salvin ; a fourth, from Costa Rica, has been described by Dr. Cabanis as 

 C Salvini, after the same gentleman. Very considerable difference occurs in the sexes, but more in colour than in 

 form ; for the females have the tail forked like that of the males, but to a much less extent.

The C. Salvini is nearly alUed to C. Osberti and to C. Caniveti, but I believe it to be distinct from both. The
