GREEN SUN-FISH. 939 
lowish; iris red ; cheeks with narrow wavy stripes of bright blue; usually a round black 
spot on last rays of dorsal and anal behind, the latter, and sometimes both, obsolete. 
A species extremely variable both in form and coloration, yet easily recognizable at 
‘sight. As is the case in many species, specimens from tributaries of Lake Michigan in 
Wisconsin are deeper-bodied and darker-colored than those from the Ohio River. This 
species reaches a length of about eight inches, but they are usually seen of a much 
smaller size. 
Habitat: Lepomis cyanellus abounds throughout the entire Mississippi Valley and in all 
the streams tributary to the Gulf of Mexico. It occurs more sparingly in the tributaries 
of the Great Lakes, and has not been noticed at all east of the Mountains. Throughout 
the Ohio Valley, it is one of the most abundant of fishes, occuring in every pond, and 
ascending small streams, where in may be found lurking in deep holes and under every 
projecting root. It is too small to be of much account as a food fish and is valued 
chiefly by the boy. ; 
Diagnosis.—The elongated body, large mouth and low spines at once dis- 
' tinguish this species. It is the only species in Ohio which has but three 
anal spines, and a distinct supplemental maxillary bone, which has no 
teeth on the tongue.

Type, Calliurus melanops, Girard, = Pomotis gulosus C. & V. 
_ Etymology, chaino, to yawn; brytius, an allied genus = Apomotis. 
Dorsal fin much more developed than anal fin, its base about twice that of the latter, 
the soft parts of the two fins nearly equal and terminating at the same vertical behind ; 
dorsal spines strong, ten in number; anal spines three; caudal fin emarginate; dorsal 
fins not notched; mouth very large, the maxillary reaching to opposite the posterior 
margin of the eye, very broad and flat, with a very large supplemental bone; palatine 
teeth very strong; a conspicuous patch of teeth on the tongue and on the pterygoid 
bones ; gill-rakers long, very strong, armed with strong teeth; opercle ending behind 
in a large but rather short rounded process or flap; lower jaw longest; body stout, 
heavy, moderately elongate; aspect and dentition of Ambloplites. This genus contains 
so far as is known but two species, both large, Stout Sun-fishes, voracious in habit, re- 
rembling Bass. The second species, Chenobrytius gulosus (Cuv. and es Cope, occurs 
only in the South Atlantic and Gult States.
