Lepomis auritus Linn Jordan. Ichthelis rubricauda Holbrook. 
Lepomis apiatus sp. nov. 
A species of discoid form, possessing a well developed patch of teeth on 
the palatine bones. The gill rakers, although elongate on the anterior half 
of the first branchial arch are obtuse at their extremities ; they are quite 
robust, and become shorter on the inferior portion of the arch. 
The depth of the body is contained in the total length (with caudal fin) 
2.27 times, and the length of the head enters the same 3.3 times. The 
orbit is as wide as the length of the muzzle, and enters the length of the 
4.25 times, and equals the inter-orbital width. The extremity of the 
maxillary bone reaches the vertical line marking the anterior two-fifths of 
the orbit. 
The dorsal spines are robust and high, and are as long as the soft rays; 
The caudal fin is slightly emarginate. The ventral reaches the first and 
the pectoral the second anal spines. Radial formula; D. X-11; A. III-10; 
P. 12. The opercular flap is short. Scale formula 6-44-12 ; six rows on 
the preoperculum below the eye. Opercle scaly. 
Color, brown, dark above, lighter below. Each scale has a black spot at 
the base forming together longitudinal series ; these are less distinct on 
the superior half of the sides, and are obsolete in that region in large 
specimens. ‘The spots are distinct on the opercular scales. Fins and 
muzzle black. Guill spot black, without border.

The external series of teeth are relatively larger in this species than in 
the LZ. auritus and L.mystacalis. No teeth on the tongue. 
Lepomis mystacalis, sp. nov. 
In this species the gill rakers are of the character indicated by Prof. 
Jordan as characteristic of the genus Lepomis, that is, slender and acute. 
This species also differs from the Z. wpiatus in the greater compression, 
and the shorter muzzle. 
The greatest depth enters the total length (including caudal fin) 2.5 
times, and the length of the head enters the same 4.4 times. The orbit is 
large, exceeding the length of the muzzle, equaling the interorbital space, 
and entering the length of the head 3.3 times. Radial formula ; D. X-12 ; 
A. III-12; P. 12. The dorsal spines are robust, but a little shorter than
