soft dorsal and caudal barred with dusky and orange-yellow. Pectorals 

 slightly reddish. Ventrals translucent. 



A single specimen, 3.9 inches long (numbered 36652 on the catalogue 

 of the ]!s^ational Museum), was taken by the writer and Prof. Joseph 

 Swain in the French Broad Eiver at the mouth of Wolf Creek, Ten- 

 nessee. It was found in very rapid water, lurking under the stones. 



5. Etheostoma (Hadropterus) cymatotcenia Gilbert *& Meek, sp. u. 36215, 36308, 



3S260. 



Body robust, comparatively little compressed, the ventral region very 

 prominent, rounded, the dorsal region scarcely- elevated; dorsal and 

 ventral outlines converging rapidly towards caudal peduncle, which is 

 very narrow and expands abruptly behind to form a broad basis for 

 the caudal fin. Head short, tapering rapidly forwards, the snout not 

 blunt, short and slender. Mouth small, oblique, the lower jaw included. 

 Maxillary nearly reaching vertical from front of orbit, about 4i in head. 

 Teeth in very narrow cardiform bands, the outer series in both jaws 

 rather conspicuously enlarged. Eye large, about equaling snout, 4 

 in head. Cheeks, opercles, nape and breast covered with large scales, 

 those on cheeks smaller than the others, Preopercular margin entire. 

 Gill-membranes narrowly joined across isthmus, the union being in most 

 cases hardly perceptible, but in one specimen quite broad. 



Spinous dorsal rather short and high, the first spine but little shorter 

 than the second ; anterior spines highest, the outline of the fin thence 

 declined ; highest spine equaling half the length of the head. Soft dor- 

 sal small, quadrate, as long as high, its base but little more than half 

 that of spinous dorsal ; its longest ray If in head. 



First anal spine very strong and robust, much stronger than any of 

 dorsal spines, or than the second anal spine; its length equaling dis- 

 tance from snout to center of pupil, equaling or slightly exceeding that 

 of second anal spine. Anal larger than second dorsal, its base slightly 

 longer, and the rays higher, the longest ray 1^ or 1§ in head. Caudal 

 slightly emarginate. Pectorals short, not reaching tips of ventrals, the 

 two about equal in length, equaling head behind nostrils. 



Body covered with large rough scales, everywhere spinous but with a 

 tendency to smoothness on the breast. Ventral region completely and 

 uniformly scaled without median series of enlarged plates, two or three 

 of which only are visible between the ventrals. 



Head 4 to 4^ in length; depth 5. Lateral line 64 to 70; 7 scales from 

 lateral line to middle of spinous dorsal, 12 to median ventral line.

Colors in life : Above and on sides greenish, made very dark by fine, 

 close-set, punctulations. Two pairs of light streaks along sides, narrower 

 than interspaces, becoming yellowish in spirits ; the upper pair from the 

 nape running along each side of dorsal, inclosing between them a
