Gill-membranes little connected, distances from muzzle to angle and toback of orbit not far from equal. Cheeks, opercles, nape, and breast naked; chin, cheeks, and opercles sprin-kled with fine dark dots; a large black humeral scale, its depth § diameterof eye obeyense. Cheeks, opercles, nape, and breast covered with embedded scales, chin andcheeks with pronounced dark mottlings and vermiculations; humeralscale rather small and not very black squamiceps.

Ac. Xat. Sci. Phila., 212 (Pcecilichthys). J. &G., 510 (Nanostoma); M. V., 130; B., I, 83; J. &E., I, 1075; J., 41 (Nanostoma) -F., 65; L., 28. Banded darters which have a superficial resemblance to females ofE. cceruleum, and may even be confused (especially in preservative) withE. jessue. From the first this species is easily distinguished by its closelyand finely scaled cheeks, and from both, as well as also from all other Illi-nois species of the genus Etheostoma except flabellare, it may be readilyseparated by the broad union of the gill-membranes. Length ordinarilya little less than 2 inches; body moderately elongate, considerablv com-pressed, the depth to 6 in length; greatest width of body about% its greatest depth; depth of caudal peduncle 2 .4 to 3 .1 in its in life bright olivaceous above, golden below; 6 dark brownquadrate dorsal spots, which connect by alternating
