Phaethornis fraterculus

In figuring this bird in the present monograph, I do not insist that it is a new species, or that it is by any means rare; on the contrary, scarcely a single collection arrives from Cayenne and the neighbouring countries which does not comprise examples of it. Still I cannot find that it has been described; and that it has not been is also the opinion of M. Bourcier, of Paris; and the only question in our minds is whether it can possibly be the female, or one or other sex of the P. malaris (P. superciliosus of this work). If this should ultimately prove to be the case, a similar disparity in the size of the sexes does not occur in any other species. Having said thus much, I leave the investigation of the subject to those ornithologists who may hereafter write on the subject, or to those who may have opportunities for observing the bird in a state of nature.

I ought to mention that, besides the great difference in size, the P. fraterculus differs in having a somewhat more curved bill than P. malaris.
