‘^This species resembles P. incisor {L. paIKdus) 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 jilaced immediately under the pectorals. The black o^ier- 
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 Centrarchns in the size of the mouth aud the form of the body, 
and I have no doubt it will some day become the type of a distinct 
genus.” {Agassiz.) Tennessee Elver, at Huntsville, Ala. We are 
informed by Professor Bliss that the types of this species have the 
pharyngeals paved.
