470. DIPLESION, Rafinesque. 



Diplesion, BAFINESQUE, Ichth. Ohiensis, 37, 1820, (blennwides). 

 Hyostoma, AGASSIZ, Amer. Journ. Sci. and Arts, 1854, 305, (neicmani). 



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 (blennioides) 

 19-f-23 = 42. Pyloric c(Bca 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, (rift, two; rrArjfLov, near; dorsal fin 

 nearly divided in two.) 



small, with equal jaws. Cheeks and opercles scaly; 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; spinous 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 with 8 dark cross bars; about 11 bar-like 

 blotches, somewhat indistinct, arranged along the lateral line; fins chiefly black; membranes 

 t 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 

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