single series of short conical teeth. Snout short, depressed, flat, 

 surrounded by a wreath of short tentacles ; the tentacles above 

 the orbit very distinct. The maxillary extends to below the 

 posterior margin of the orbit. A round foramen in the upper 

 part of the axil. Brown, marbled with darker ; some small, round 

 deep black spots on the side of the body ; dorsal fin with oblique 

 brown bands, pectoral with many round white spots.

The length of the head is contained three times and three-fourths 

 in the total ; the bony bridge between the orbits is narrow, its 

 width being one- eighth of the length of the head and much less 

 than that of the orbit, which equals the length of the snout. 

 Gill covers with four spines, two opercular and two subopercular, 

 one of the latter small, and nearly obsolete in old s]3ecimens. 

 Yilliform teeth in jaws, vomer, and palatines. Snout short, obtuse 

 (the upper profile parabolic) and surrounded by a wreath of 

 tentacles, those above the orbits well developed, ciliated. The 

 maxillary extends to below the middle of the orbit. No foramen 

 in the axil. The outer ventral ray much longer than the inner 

 one, tapering, nearly as long as the head. Brown marbled with 

 darker.
