Two examples of this species, 126 and 127 millimeters in length, were 

 obtained with a boat dredge at Godhavn, Disco Island, July 15, 1883. 



The body is moderately elongate, compressed, and covered with 

 small scales. The lateral line is single, well up on the back, extending 

 slightly beyond the middle of the dorsal fin. The gill-openings are con- 

 tinued forward below, the membranes united to the narrow isthmus. 

 The snout is subconical, as long as the eye, which is large and promi- 

 nent, its greatest diameter being contained 4| times in the length of the 

 head. The maxilla reaches slightly beyond the vertical through the 

 anterior margin of the eye, and its length is contained 4 times in that of 

 the head. The length of the mandible is three-sevenths of that of the head. 

 The width of the interorbital space is one-half of the greatest diameter 

 of the eye. The dorsal fin is long, of spines only ; the anal is shorter, 

 with a short antecedent spine. The caudal fin is rounded. The pec- 

 toral is well developed, not quite as long as the head. The ventral fin 

 is composed of three rays, its length being two-fifths of that of the head. 

 The length of the head is contained 4^ times, and the greatest depth of 

 the body 7f times in the total length of the caudal base. 



The color is a bright scarlet ; Hie head is marked below with 5 or 6 

 brown reticulations, and with a brown streak from the snout to the eye. 

 The vertical fins and the pectorals are marked with brown bands. The 

 dorsal fin has 5 large round black spots, each with a white band near 

 its posterior margin. These spots are placed at equal intervals on the 

 fin.
