9. Hab. Para. 
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, 
1 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 is 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.
