sides ; soft dorsal with 2 bauds ; a similar one at caudal base aud 3 narrow 

 biiuds on second half of caudal; pectoral indistinctly banded; head 

 speckled witli brown dots. (Bean.) North Pacific; the types from J /fta- 

 tross Station 2855, north latitude 57°, west longitude 153^^ 18', at a depth 

 of 69 fathoms, off Sitkali dak Island; our specimens from Puget Sound and 

 off Karluk. Concerning this speci<'8 Dr. Gilbert observes: 



''Taken at Albatross Stations 3216, 3257, 3310, 3311, and 3334, located 

 north and south of the Alaskan Peninsula, and north of Unalaska Island, 

 in 50 to 85 fathoms. Tubercles on head definitely placed; 1 in front of 

 eye; 4 above orbit, the posterior 2 the largest; a pair on middle of sub- 

 orbital stay, with a smaller one above them; 1 on temporal region, and 1 

 on shoulder; by far the largest pair on occiput, where they are high, 

 compressed spines, directed vertically upward, as long as diameter of 

 pupil; nasal spines obsolete. Cirri are generally distributed over upper 

 part of head and body, the longer ones being specially numerous on max- 

 illary, under surface of mandible, aud on the ojjercle and preopercle; of 

 the larger ones, 2 often proceed from 1 base; a series of short filaments 

 along ujiper edge of pupil. Mucous pores large, those of the mandibular 

 and buccal series slit-like. In adults the dorsal bands break up into 

 series of spots aud become inconspicuous." {seta, bristle; gcro, I bear.)

 Gills 3^, no slit behind the last arch; gill membranes broadly joined to 

 the isthmus, their union extending to above the lower edge of the base of 

 the pectorals. Pseudobranchite very small; no cirri, scales, or prickles; 

 the skin thin and movable, smooth, or roughened with small warts. 

 Spinous dorsal little developed, the 2 fins usually continuous; spines very
