I have hitherto followed Girard in identifyiog this species with Siluriis 

 catus of Linnaeus, but a glance at the original desciiption 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 

 Eafinesque 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 ?) cupreus 

 in having the jaws equal. The form called coenosus 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 Eiver, Georgia, I refer to aiitoniensis. 

 They are shore in body, with a swollen nape and a rather longer anal fin.
