As a new species, it appears, therefore, pretty certain that we have to acknowledge the late Dr. Shaw as the first author by whom this interesting bird was introduced to the knowledge of the learned world: he describes it, as before observed, under the name of Pipra punctata. M. Vieillot is consequently in an error when he refers to authority of Dr. Latham for this name. The bird was so designated in the first instance, in the work entitled the _Naturalist’s Miscellany_, written by Dr. Shaw; nor was the species mentioned by Dr. Latham either in his Synopsis or his Index Ornithologicus. In a final or second supplement published by Dr. Latham long after the Synopsis, we find the bird mentioned under the name of the _Speckled Manakin_, but only upon the authority of the Naturalist’s Miscellany of Shaw, and a drawing of the bird by General Davies, for at that late period even, the bird appears to be unknown to Dr. Latham, except upon those two authorities. This observation is the more material since the Ornithologist M. Vieillot in dividing the Linnæan Genus Pipra into two Genera, Pardalotus and Pipra, assigns for the type of his genus PARDALOTUS the “_Pipra punctata_” of Latham, at the same time, as we have already shewn, the works of Dr. Latham affords us no such name. The present species was described under the appellation of _Pipra punctata_ only by Dr. Shaw. Dr. Latham does not adopt this name, he records the species only under the trivial english name of the Speckled Manakin, which name had also been assigned before by Dr. Shaw. If, therefore, the name of Pipra punctata had occurred to M. Vieillot, it must have been in the work of Dr. Shaw, and not of Dr. Latham. Perhaps Vieillot had inadvertently imagined this Speckled Manakin to be the same as the Spotted Manakin of Dr. Latham’s Synopsis. If this be really the source of error, it may be added, that this latter bird appears to have been described by Dr. Latham upon the authority only of Planches Enluminées, and is no other than Pipra Nævia of Gmelin, as Dr. Latham has himself pointed out in his Index Ornithologicus. The description of this bird, as it occurs in the first instance, in the works of Dr. Shaw, is to this effect. PIPRA PUNCTATA (SPECKLED MANAKIN) _grisea_, _fusco undulata_, _vertice alisque nigris_, _albo punctatis tectricibus caudæ rubris_. The notice of the species as before-mentioned in Dr. Latham’s second Supplement is subsequent to this, and appears only under the trivial name of the Speckled Manakin.
