JULY, 1907. FISHES OF GREAT LAKES, NICARAGUA MEEK. 125 



Head 2.4; depth 2.3 to 2.5; D. xvi to xvn 10 to 12; A. vn, 8; 

 scales 7-32-11. Body elongate, in general form like the preceding; 

 maxillary 2.8 to 2.9 in head; snout 2.2 to 2.4; mandible 2.2 to 2.4; 

 interorbital 3.6 to 3.9; preorbital 4.3 to 4.6; postorbital 2.4 to 2.7; 

 diameter of eye 4.4 to 4.6; eye to subopercle 2.8 to 3.0; lips and denti- 

 tion as in the preceding species; last dorsal spine 2.7 to 3.0 in head; 

 last anal spine 2.5 to 2.8; pectoral 1.3 to 1.4; ventral 1.3 to 1.5; 

 length of caudal peduncle 3.8 to 4.2, its depth 2.8 to 3.1 ; origin of dor- 

 sal to snout 2.1 to 2.3 in body; base of anal 3.8 to 4.0; snout to scales 

 on nape 1.8 to 1.9 in head; scales on cheeks usually in 3 rows, seldom 

 in 4 rows ; gill rakers 4 + 10 or 1 1 . 



Color red to nearly black ; some individuals with only tips of caudal 

 and dorsal fins with black; others with small patches of red on ventral 

 region; darkest individuals with traces of black bars and spots on 

 side, suggesting markings of the following species, with which this 

 species may prove to be identical. The specimens seen and collected 

 by me average smaller than those of following species, but the grada- 

 tion in color and general appearance of the material examined by me 

 is not sufficient to justify the uniting of these two species.
