 ray exceeding length of snout; longest ray of soft dorsal slightly more 

 thani head; all the rays of dorsal and anal fins simple, unbraiiched; 

 caudal long and narrow, nearly truncate when spread, f length of head; 

 9 caudal rays are branched at tip for about \ length of rays. The pectoral

 the next 6 or 7 forked, the remaining rays being thickened with incised 

 membranes ; ventrals with 1 spine and 4 rays, not reaching vent, If in head. 

 Lateral line conspicuous anteriorly, running high, interrupted under 

 eleventh or twelfth ray of soft dorsal, a mere trace visible thence to base 

 of caudal. Sides of body thickly covered with coarse prickles, the head, 

 the breast, belly, and a narrow strip along base of anal fin naked. Color 

 light brownish, faintly verrniculated with darker, with traces of 5 irregu- 

 lar cross bars from back, and a narrow distinct bar at base of caudal; 

 pectorals, dorsal, and caudal cross-barred. Characterized by the long 

 slender body entirely covered with coarse prickles, the short spinous 

 dorsal very broadly united to the very long soft dorsal, the long anal fin, 

 the incomplete lateral line, the very large pores on head, the branched 

 pectoral rays, and the absence of any distinctly projecting preopercular 

 spine. One specimen, 2 inches long, from Lost River, near Klamath
