breast; nape covered with small scales. Opercular spine well developed. 

 Gill membranes scarcely connected. Scales on body small, firm, ctenoid; 

 a small, black humeral process. Lateral line nearly straight, becoming 

 obsolete under last rays of second dorsal; belly covered with ordinary 

 scales. Dorsal spines slender, rather high ; soft dorsal rather higher, its 

 base shorter ; anal nearly equal to soft dorsal, its base somewhat shorter, 

 its rays a little higher; anal spine slender, single in the typical example, 

 the normal number probably 2; caudal truncate, \\ in head, about as 

 long as the ventrals, which are rather shorter than the pectorals. Color 

 in life dusky green, with markings of darker olive, the latter forming 

 about 9 obscure cross bars, which are about as wide as the interspaces, 

 these most distinct posteriorly and below the lateral line ; a dusky spot 

 at base of caudal ; a roundish orange spot in each of the pale interspaces 

 between the bars along the sides; some minute orange spots above the 

 lateral line ; a narrow black streak along side of head through eye ; a 

 pink spot in front of eye above; snout tinged with orange; first dorsal 

 translucent, with a narrow edge of orange; soft dorsal translucent, 

 speckled with dusky and pale orange ; tail with 3 or 4 alternate bars of 

 orange and dusky olive, the marking not very sharp; pectorals similarly, 

 but more faintly, marked, orange at base; anal and ventrals colorless. 

 Breast not blue nor orange. Length 2 inches. Head waters of Cumber- 

 land River ; only the single type known, perhaps the type of a distinct 

 genus, (sagitta, an arrow.)
