Head 3i; depth i\. D. VII, 21; A. 15; P. 16; V. 1,4; eye 4; snout 4; 

 interorbital width 5^. Least depth of caudal peduncle greater than 

 snout, 3| in head; interorbital space rather broad, about 1^ in eye. 

 Body deeper and more compressed than in any other species known to us, 

 this being especially noticeable posteriorly; caudal peduncle very short 

 and deep, and entirely overlapped by posterior dorsal rays which extend 

 beyond base of caudal fin. Length of caudal peduncle from base of last 

 dorsal ray about f depth of same ; depth of body at origin of anal fin f 

 length of head. Interorbital space slightly concave; occiput flat or 

 transversely convex. Mouth oblique, the maxillary reaching vertical 

 from posterior margin of pupil, 2+ in head. Teeth in a very narrow 

 crescent! c band on vomer, none on palatines. Upper preopercular spine 

 short and broad, curved or simply directed upward; below this are 2 

 stout, blunt spines directed downward. Body entirely naked, lateral line 

 incomplete, not reaching end of soft dorsal. Spinous dorsal low, the 

 longest spines not greater than length of snout ; soft fins all high, the 

 fifteenth dorsal ray equaling snout and eye; a broad membrane always 

 connecting the 2 dorsals, the notch inconspicuous; last rays of anal, as 

 well as dorsal, extending l)eyond base of caudal; first anal ray under 

 third ray of soft dorsal; ventral spine and rays slender and weak. Anus 

 midway between base of caudal fin and front of eye. Color in alcohol, 

 back and sides with vermiculations of light and dark, the back with 5 or 

 6 ill-defined black cross bars, which usually reach the lateral line ; the 

 usual black bar at base of caudal, emarginate posteriorly ; below the lateral 

 line a number of small, quadrate dark blotches, arranged in 2 irregular 

 series; lower part unmarked, except with fine dark puuctulations; dor- 

 sal, pectoral, and caudal fins cross-barred with dark; anal and ventrals 

 with numerous small dark specks. Length about 3| inches. Shookum- 

 chnck and Newaukum rivers, near Chehalis, in western Washington.
