DARTERS FROM LAKE MAXINKUCKEE. 367 



This species differs from H. scierns chiefly in the much larger month, the longer 

 maxillary, the larger scales, the fewer scales on the opercle and cheek, the free gill- 

 membranes, the smooth preopercle, and closer approximation of the dorsal fins. 



One example, 3.5 inches long, taken in Anbeenaubee Creek, the eastern inlet of 

 Lake Maxiuknckee, abonthalf a mile from the lake, August 4, 1899. 



Type No. 49378, U. S. N. M. Evermann & Scovell, collectors. 



Etheostoma aubeenaubei Evermann, new species. 



Head 3.6; depth 5; eye 4; snout 5; maxillary 3; iuterorbital 5; D. x-11; A. ii, 8; 

 scales 4-58 to 63-9, 8 to 24 pores. 



Body rather elongate, not much compressed except posteriorly ; head rather short; 

 snout short, somewhat decnrved; mouth moderate, slightly obli(ine, lower jaw in- 

 cluded, maxillary reaching past front of orbit ; eye rather small, above axis of body ; 

 premaxillaries not protractile; gill-membranes free from the isthmus and each other. 

 Fins not large, the dorsals usually distinctly but narrowly separated, sonu^times 

 scarcely se^iarate; origin of spinous dorsal one-third distance from tip of snout to 

 base of caudal; outline of spinous dorsal gently rounded, the longest spine about 3 

 in head; longest dorsal ray about 2; first anal spine longer, and slightly stronger 

 than second, 3 to 3.5 in head; longest anal ray about 2; pectoral short, about 1.3 in 

 head; ventrals close together, about 2 in head; caudal rounded, 1.5 in head. Scales 

 rather small, rough-ctenoid; lateral line incomplete, usually developed on only 8 to 

 24 scales at anterior end ; cheek usually naked, or with a few small, more or less 

 embedded scales; opercle usually about half-scaled, sometimes with but few scales; 

 breast always naked ; belly with ordinary scales ; nape usually densely and regularly 

 scaled, occasionally some scales embedd'Cd ; preopercle entire; opercular flap mod- 

 erate, broad; opercular spine rather small; no humeral spot or process. 



Color in life, greenish brown above, side with about 12 or 13 vertical, dark 

 blotches, separated by pale orange-red areas of similar size ; another series of similar 

 but smaller orange blotches along lower part of side anterior to anal fin; under 

 parts whitish; caudal peduncle grayish ; head dark above; opercle and cheek dark, 

 with greenish shade; a dark line downward from eye; snout grayish; spinous dorsal 

 with a narrow dark border, below which is a broad orange band, then a broad but 

 irregular dark band near base of fin ; soft dorsal and caudal barred with white and 

 grayish, the latter in spots on the rays ; anal and ventrals without markings ; pec- 

 toral somewhat dusky. 



This species is close to E. iowce, from which it is evidently descended, and from 

 which it differs in the almost naked cheek, the less complete scaling of the opercle, 

 the somewhat longer maxillary, more oblique mouth, much closer approximation of 

 the dorsal fins, and the coloration. 



Many examples, each about 2 inches long, taken in Anbeenaubee Creek, the east 

 inlet of Lake Maxinkuckee, August 4 and 23, and on other days iu August and Sej)- 

 tember. 1899.
