 or nearly so. Scales rather large, the helly scaled like the sides. Gill 

 membranes not described. Lateral line straight, reaching middle of

470. DIPLESION, Rafinesque. 



Diphnion, Rafinesque, Ichth. Oliieusis, 37, 1820, {hleunioideif}. 

 Jlyostoma, AoASSiz, Amer. Jouni. Sci. and Arts, 1854, 305, {nerniiani). 



Body rather elongate, subterete. Head very short and blunt, with 

 tumid cheeks; the profile very convex. Mouth small, inferior, hori- 

 zontal. Premaxillaries protractile, little movable, joined to the forehead 

 mesially by a slight frenum ; maxillary not protractile, adnate for most 

 of its length to the fleshy skin of the preorbital ; lower jaw very short; 

 teeth in jaws strong; no teeth on vomer or palatines. Gill membranes 

 broadly connected. Gill rakers very short. Scales moderate, rough. 

 Lateral line complete; no enlarged ventral plates. Dorsal fins large, the 

 spinous dorsal longer and lower than the second, of about 13 spines; 

 anal smaller than second dorsal with 2 strong spines. Ventrals moder- 

 ately separated; pectorals long, symmetrical. Vertebrae {blennioidcs) 

 19 + 23 = 42. Pyloric cceca 4. Frontal region of skull very narrow; 

 ethmoid region abruptly decurved. Parietal region moderately convex 

 (less so than in Etheostoma, more so than in Boleosoma); no supraoccipital 

 crest. Coloration largely green. {i)ic, two; umjc/iov, near; dorsal fin 

 nearly divided in two.) 



small, with e(iual jaws. Cheeks and opercles scalj-; the cheek scales small and closely set; a tri- 

 angular series of scales on temporal region; throat smooth; neck above closely scaled; belly 

 closely scaled. Fins large; s]iinims dorsal high, the second still higher, but smaller than the 

 first, its base about equal to the length of the head; dorsal fins contiguous, slightly connected. 

 Color olivaceous; head above entirely black; back witli 8 dark cross bars; about 11 bar-like 

 bl'jtclies, somewhat indistinct, arranged along the lateral line; fins chiefly black; membranes 

 of the second dorsal and ventral fins entirely black, that of the spinous dorsal with a broad 

 black horizontal bar at base, above which are numerous distinct black oblique streaks; anal 

 with a broad black bar; caudal and pectoral fins largely dusky. Females and young probably 

 paler. Scales 7-58-8. Length 2}^ inches. Cumberland River. It is probably identical with 

 Ulocentra simotera, (aler, black; pinna, fin.)
