est, being contained in the head 2-jV times; membrane between each 2 

 of the last 4 rays incised; caudal slender, rounded behind, its length a 

 little more than twice in head. Diameter of ventral disk 8 in body. Skin 

 very loose, attached only at opening and to ends of last rays of dorsal and 

 anal and to base of caudal. Color dark, covered with fine punctulation ; 

 belly and underside of head free from markings; last half of dorsal darker 

 than anterior half; anal mottled with black ; caudal with 2 black vertical 

 bands, the first bony and just back of tips of last dorsal and anal rays ; the 

 second band slender and faint and at top of fin. Arctic Ocean ; several 

 specimens were taken at Herschel Island. The longest specimen is 2^ 

 inches long. This species is nearest L. tunicatus from the coast of Greenland, 

 and appears to be intermediate between it and L. agassizii.

Head 3f in length of body ; depth 4|. D. 39 ; A. 30 ; pectoral 36 ; caudal 

 12; eye 8 in head; maxillary 2; snout 2|; gill opening 2f ; upper pec- 

 toral lobe -J-; lower lobe 1-J-; intervening rays 2; ventral disk 2; highest 

 dorsal rays 2|; highest anal rays 2f ; caudal rays If. Body moderately 

 elongate, much compressed posteriorly, slightly so anteriorly; head mod- 

 erate, the cheeks and nape prominent. Mouth wide, with little lateral 

 cleft; maxillary extending to below the anterior margin of eye, its end 

 covered with the skin of the head; the lower jaw slightly the longer; the 

 teeth tricuspid, those on the inner part of jaw largest, arranged in about 

 14 series in each jaw; series nearly transverse on middle of jaw, becoming 

 more and more oblique toward the sides, where they are nearly parallel 

 with the sides of the jaws; interorbital wide, slightly concave; nostrils 

 ending in very short, wide tubes, the posterior over the anterior margin 

 of eye, the anterior in front of it a distance equal to the diameter of eye ; 

 opercle ending in a short, wide spine covered with skin; it is situated 

 slightly above the middle of gill opening; gill opening running from 

 about the eleventh pectoral ray to a level with the eye. Origin of dorsal 

 slightly behind base of pectoral, its distance from the snout 3 in length 

 of body, its anterior rays short, gradually lengthening posteriorly, the 

 rays from the anterior third to near the end about equal, the last ray 

 abruptly shortened, forming a slight notch where the fin joins the caudal; 

 posterior of caudal free above ; anal similar to dorsal, about the same 

 height, its origin nearer snout than base of caudal, about under the base 

 of the tenth dorsal ray, posteriorly it is longer than the dorsal, joining 

 the caudal at about ^ its length ; ventral disk nearly round, its distance 

 from tip of lower jaw 1 in its diameter, 1 in distance from vent, 2 from 

 first anal ray ; vent midway between front of anal and edge of disk; upper 

 lobe of pectoral broadly rounded, reaching to $ of the distance between 

 vent and front of anal; lower lobe long, reaching nearly to vent; caudal 

 long and slender, rounded behind. Skin very thin and loose on body and 

 head, covering the anterior parts of dorsal and anal, attached at about the
