gray, dusky below ; a black baud from mouth across orbit to pectoral and 

 alongside of body, much iuterrupted; dark markings deepest on sides 

 of body; a dark cross band halfway between occiput and dorsal, 1 in front 

 of dorsal, 1 under posterior half of dorsal (running up on latter), and about 

 2 on caudal peduncle; posterior half of dorsal dark, marbled; a marbled 

 patch at base of pectorals, another on their distal third; ventrals pale in 

 both sexes; anal Avith dark patches on or behind the rays, darker posteri- 

 orly; caudal black at its base and on its distal half, the 2 patches con- 

 nected by a black baud along middle of fin, leaving 2 light patches on the 

 dorsal and ventral thirds of the proximal half of the fin ; the bands of 

 color very much as in A. monopterygius, but better defined. Length 4 

 inches. Coast of Alaska, south to Vancouver Island; not abundant; 

 recorded from Vancouver Island (Giinther) ; eastern Aleutian Islands, 34 

 to 59 fathoms, and Bristol Bay. (Gilbert.) Here described from speci- 

 mens from the Aleutian Islands and Bristol Baj^. (inermis, unarmed.)

Mr. Garman (Monograph of the Discoboli, 181)2, 19) has the following remarks on the 

 Cyclopteridce: 



"Anteriorly the form of the lump fishes is stout, thick, and deep; behind the body 

 cavity, which occ\ipies the greater portion of the length, it rather abruptly becomes 

 weak and slender. The head is short and broad, sub(iuadrangular in transsection ; the 

 snout is short and blunt; the mouth is of moderate width, anterior, and opens slightly 

 upward; the teeth are small, subconical, and arranged in a band or cord; the eyes are of 

 medium size and have a lateral outlook. All of the members of the family have pseudo- 

 branchife, 3§ gills, branchiostegal rays, small gill openings, numerous pyloric ca^'ca, 

 and an elongate intestine. In their lower portions the broad, rounded pectorals extend 

 forward under the throat, along the sides of the disk. The vertical fins are not of large 

 extent; the caudal and the 2 dorsals are quite separate. The disk is comparatively large. 

 Early in life the skin is teiiihr and naked; later it grows tough and is covered with 

 roughened or spine-beaiiiig osst .his tubercles. Semicartilaginous describes the skeleton 

 with tolerable accur;ii\ t he siuull ;nnouut of bony matter lies in thin plates, often form- 

 ing cells and chambers similar to those to be noticed in the bones of Lophius. The third
