"This species resembles P. incisor (L. paUidus) in the outline of the 

 body, the nature and coloration of the scales, and in the size and form 

 of the fins, but it differs greatly from it by its large mouth, the free 

 extremity of the upper jaws reaching the vertical line of the middle of 

 the eye, by the presence of teeth upon the palate, and by the ventral 

 fins being placed immediately under the pectorals. The black oper- 

 cular appendage, which is very short, has a narrow orange border be- 

 hind; there is a black spot at the base of the posterior rays of the 

 dorsal; both dorsal and anal are marked by one or two dark stripes; 

 the caudal is crossed by several dotted vertical lines; there are eight 

 or nine dusky bars across the sides between the head and tail. This 

 species bears the same relation to Pomotis that Pomoxis bears to the 

 true Centrarclms in the size of the mouth and the form of the body, 

 and I have no doubt it will some day become the type of a distinct 

 genus." (Agassiz.) Tennessee Eiver, at Hunts ville, Ala. We are 

 informed by Professor Bliss that the types of this species have the 

 pharyngeals paved.
