translucent, dusted with minute dark points, margined with blackish. 

 Traces of orange markings on lower side of head, and on bases of pec- 

 toral fins; caudal apparently tinged, in life, with light yellow. 



Several specimens were collected and forwarded to the writer by 

 Prof. F. W. Cragin, who took them in a small weedy stream connecting 

 the "Lake" at Garden City, Kans., with the Arkansas River. A single 

 specimen was also taken in Snokomo Creek, Wabaunsee County, Kansas. 



18. Etheostoma (Etheostoma) tuscumbia Gilbert & Swain, sp. nov. 3G154. 



Body exceedingly heavy and robust, with elevated back, and broad, 

 thick head. Anterior profile descending rapidly from front of dorsal, 

 the snout blunt and broadly rounded, but not overhanging the mouth. 

 Gape large and wide, the mandible little included, the maxillary reach- 

 ing vertical from middle of orbit, 3 in head. Eye rather small, 4J in 

 head, the interorbital width two-thirds its diameter. Preopercular 

 margin entire. Cheeks, opercles, nape, and top of head generally 

 scaly, only the snout, interorbital space, and preorbitals naked. Oper- 

 cular spine little developed. Branchiostegal membranes scarcely Joined 

 across isthmus. 



Fins all very small. Dorsal spines weak, the median spines highest, 

 half length of head; soft dorsal scarcely higher than spinous; anal fin 

 with a single, rather weak spine, the first soft ray articulated and 

 branched. Pectorals and ventrals very small, the latter not reaching 

 I distance to vent ; length of pastorals equaling distance from tip of 

 snout to preopercular margin. Caudal broadly rounded. 



Head 3 J to Sf in length ; depth 4 to U. D. IX or X, 11 to 13 ; A. I, 

 s. Lateral line 50 ^^o or 50 ^\. Length 2 inches. 



Scales rough, wholly enveloping head and body except snout and in- 

 terorbital space. Lateral line incomplete, arched, following the curve 

 of the back. Pores absent on 15 to 18 scales. 



Color in life : Varying shades of grayish and greenish olive, much 

 mottled and speckled with black. Six broad, dark bars across back ; 8 

 or 10 linear black blotches along lateral line separated by silvery inter- 

 spaces. A dark streak before, one below, and one behind orbit. 

 Opercle and top of head dusky. Pectorals with several dark bars, ven- 

 trals unmarked. A black blotch at base of each caudal lobe. Other 

 fins more or less barred with light and dark. 



This species differs from all those hitherto referred to the group Etheos- 

 toma in having a single anal spine, and will have to form the type of a 

 new genus, if we attempt to recognize as genera such groups as Nanos- 

 toma, Nothonotus, Hadroptertis^ &c. 



Etheostoma tuscumbia was found exceedingly abundant in the stream 

 flowing from the large spring at Tuscumbia, Ala. 



19. Etheostoma ( Alvarius) fonticola Jordan & Gilbert, sp. nov. 36523. 



Moderately compressed and elevated, the two outlines about equally 

 arched ; head short and deep, with very short snout ; mouth terminal,
