SYLVICOLA OLIVACEA.—(Giraud.) The Orange-breasted Warbler. PLATE XLVIII. Adult.

Of this handsome and peculiar-looking Warbler, unfortunately we can say very little. It is known as a bird of Mexico, but has been noticed within the limits of the United States, as yet, in one instance only, having been received from Texas by our friend, Mr. Jacob P. Giraud, Jun., of New York. At the period of its receipt it was unknown to ornithologists, and it was accordingly described by Mr. Giraud, with other new and interesting species, in his “New Species of Birds of North America.”

Since the time of the discovery of this bird, we have looked for it, with constant interest, amongst the many new and little-known birds collected by American naturalists in Texas, but in vain. It has not yet appeared again, and is to be regarded as one of the now numerous birds of our country, of which the history remains to be written by the future naturalist.

The Baron Du Bus, an ornithologist of Belgium, has received this bird from Mexico; and specimens, also from that country, are in the collection of the Philadelphia Academy. The short notice of it by the author just mentioned in the Bulletin of the Royal Academy of Brussels, contains no account of its history or of its habits; nor have we any information from other sources. From the fact of its visiting Texas in the summer, however, we infer that it is a species of which the Southern range probably extends into Central or perhaps South America.

In general appearance, this bird somewhat resembles the Prothonotary Warbler (Helinaia protonotaria), of the United States, but is much darker colored, and it does not belong to the same group or sub-genus.

The figure in our plate is about two-thirds the natural size.

The plant represented is a species of Asclepias from Texas, raised from the seed by our friend, Mr. Kilvington.

This bird presents some affinities and resemblance to the Sylvicola protonotarius of the Southern United States, but is much darker colored, and may readily be distinguished from that or any other species with which we are acquainted.
