row band of prickles in axil of pectorals, behind this a wide naked area 

 extending downward and backward to behind base of ventral s, the 2 

 areas separated by a narrow mesial band of prickles on belly ; similar 

 prickles cover continuously the occiput, the opercles, and the portion of 

 cheeks and preopercles which lie above suborbital stay ; a narrow length- 

 wise band of prickles on cheek below suborbital stay, the lower side of 

 head together with snout and inteorbital region otherwise naked ; a series 

 of 34 broad plates along each side of dorsal fins, extending from the nape to 

 the middle of caudal peduncle ; each plate transversely angulated, the outer 

 half directed outward and downward, the inner half nearly horizon- 

 tal inward, the angle bearing a very strong, compressed, backwardly 

 hooked spine ; the dorsal fins thus occupy the middle of a flat dorsal strip, 

 bounded by the 2 series of spines; a number of enlarged spine-like prickles 

 accompany the lateral line, each pore of which lies in the axil of one such; 

 anteriorly, these prickles are arranged somewhat definitely in pairs, 2 to 

 each pore, but this arrangement is lost posteriorly ; a series of enlarged 

 prickles is placed convexly at base of caudal fin ; the upper unmodified 

 rays of the pectoral fin, and all rays of dorsal and caudal fins, accompa- 

 nied by series of prickles; other fins and thickened pectoral rays smooth. 

 Body without filaments. No barbels at chin nor on mandible elsewhere. 

 A slender tentacle, palmated at tip, above posterior portion of orbit, its 

 length slightly less than diameter of pupil. A slender branched tentacle 

 near base of middle and lowermost preopercular spines, and a simple one 

 at an equal distance below them ; a similar broadly palmated tentacle on 

 cheek, behind end of maxillary, lost on 1 side in our specimen, but the 

 scar apparent. Dorsal fins separate, the membrane from last spine join- 

 ing base of first soft ray ; spines very slender, the sixth the longest, 2 in 

 head, very slightly shorter than the soft rays ; base of spinous dorsal \\ in 

 head, of soft dorsal 2f in length of head and body ; front of anal under 

 twelfth dorsal spine, the longest ray $ head, the length of the base slightly 

 less than -J head and body; caudal rounded, If in head; the lower 6 pec- 

 toral rays simple, thickened, exserted, the membranes very deeply incised, 

 the upper 3 longer than the branched rays above, the longest extending 

 to opposite fifth anal ray ; ventrals broad, the inner rays shorter than the 

 outer, which extend to opposite second anal ray. Color in life, light 

 olivaceous, with 4 brown cross bands, 1 under spinous dorsal, 3 under soft 

 dorsal; a series of 9 roundish dusky spots along middle of sides below 

 lateral line; back and sides with small golden spots and streaks; a dis- 

 tinct series of round blue spots above lateral line, and some scattered 

 blue spots and blotches 011 back and head; iris green and dusky; spinous 

 dorsal light green, crossed by narrow yellow lines; soft dorsal translu- 

 cent, shaded with reddish and bluish; ventrals translucent, posteriorly 

 greenish, with white pigment; pectorals translucent, the rays crossed with 

 reddish and greenish bars, which are little conspicuous ; supraorbital cir- 

 rus green; preopercular cirri white. Coast of Oregon (Gilbert); 1 speci- 

 men, 165 mm. long, dredged in 75 fathoms. (Named for Dr. Wilbur Wilson 

 Thoburn, in recognition of his work on the Cottidce.)
