I have hitherto followed Girard in identifying this species with Silurus 
catus of Linnzeus, but a glance at the original description is sufficient 
to show the error of such an identification. The first name in order of 
time which seems to have been given to this species is that of Pimelodus 
natalis Le Sueur, but the best of the early descriptions is that of 
Rafinesque as Pimelodus lividus. 
The original description of cupreus is incorrect in ascribing 15 anal 
rays instead of 25. This is probably a misprint. The form or subspe- 
cies here indicated as cupreus is the one most widely diffused. The type 
of Girard’s catus differs only from specimens labelled (by him?) eupreus 
in having the jaws equal. The form called ca@nosus seems to differ 
chiefly in coloration; this species, like most others, being of a much 
darker color in the Northern Lakes. 
A. antoniensis Grd. is also slightly different in form. The specimens 
obtained by me in the Etowah River, Georgia, I refer to antoniensis. 
They are short in body, with a’swollen nape and a rather longer anal fin.
