Colour.-Carapace mahogany-brown, clothed with converging lines of short grey-green hairs. Sternum, coxa of pedipalp, and legs velvety black; inner margin of former fringed with fiery-red hairs. Abdomen and legs clothed with black hairs beneath, becoming rufous above ; third and fourth pairs clothed with long, The name vestiaria was evidently not. intended by DeGeer as a specific name, but was only used as a term in the description. Ausserer, however, did not notice this and regarded it as a specific name, although the name avicularia in any case has priority. Perhaps Ausserer considered it unadvisable to have both generic and specific name the same, and the legitimacy of this combination in practical nomenclature is still a matter of disputation amongst scients. This is possibly drawn from a faded specimen of A. avicularia, for Koch remarks that the figure ia drawn from an old specimen. This figure is certainly similar in coloration to numbers of young Avicularia taken by myself in the neighbourhood of Para. |
