termaxillary band of teeth % of head. Caudal deeply 

 forked, the upper lobe the longer. Barbels long, those 

 of the maxillary extending past the gill opening. Sides 

 zvith scattered hair-like cirri. These are very noticeable 

 under a lens, but not readily distinguished by the naked 

 eve. 



This genus differs from all others of the family in hav- 

 ing hair-like cirri on the sides. It differs from Ictalurus 

 in having the occipital process and the interspinal buckler 

 widely separated and connected by ligament; from Am- 

 eiurus in having a narrow head and a deeply forked 

 caudal.
