It may be asked, what is our present knowledge of the existing species of Humming-Birds, and if there may not be others to be discovered in the great primeval forests of the western and other parts of the ou covinent of the new world. My reply is that, in all probability, many more than are known to us do exist, and that a very lengthened period must elapse before we shall acquire anything like a perfect knowledge of the group. Whatever I may have done towards the elucidation of Be SH aeeh I ye? ony be regarded as a pioneer for those who, in future ages, will render our acquaintance with this family of birds so much more complete than it is at the present time. The regions of South America whose productions are least known are Costa Rica, Veragua, Panama, the sea-bord between Carthagena and Guayaquil, the forests of La Paz and other parts of Bolivia, the whole of the eastern slopes of the Andes bordering Peru and Ecuador, and the western portion of Brazil. All these countries will doubtless furnish new kinds of Humming-Birds when the explorer shall extend his researches into their unknown recesses. We may feel fully convinced that such will be the case from the circumstance of single individuals in a youthful or imperfect state, which we cannot identify as belonging to any known species, occasionally occurring in the great collections sent from time to time to Kurope. My own collection contains several examples of this kind, which will doubtless at some future day prove to belong to unde- scribed species. For more than twenty long years have I been sending the most earne st entreaties, accom- panied with drawings, to my correspondents in Peru and Ecuador for additional examples of that truly These entreaties have been backed by the offers of large sums of money to any person who would procure them ; wonderful bird the Loddigesia mirabilis. but up to the present moment no second example has been obtained. Probably the single individual killed by Mr. Matthews in the ne ighbourhood of Chachapoyas was one which had accidentally strayed beyond the area in w hich the species usually dwells, and which has not That it may be a nocturnal bird has sometimes suggested itse this may be the reason why it has not since been seen. yet been discovered.
