 specimens the upper parts are mottled with dark colors; lower 

 parts yellowish; dorsal, caudal, anal and ventral fins dusky, pec- 

 torals lighter. Body quite heavy, compressed, very short; back 

 much elevated, making the outline nearly oval; mouth small, 

 oblique, maxillarj' extending to the front of the eye socket. Outer 

 teeth of the jaws larger than the others, palatine bones with teeth. 

 Pharyngeal teeth, strong, blunt, and not very close to each other. 

 Gill rakers short and stout, about 8 in number. A small supple- 

 mental maxillary bone. Opercular flap about as long as the snout, 

 edged with a broad, pale membranous portion. Head contained 3| 

 times in the length. Depth 2 2-5. Dorsal fin, X, 11, spines short,

 near Gull Lake (Nat. Hist. Surv., 1893).
