The heirfit of the bodv is two-fifths of the total length. 



A single much injured specimen, 23 inches long, was obtained off the coast of 

 Greenland.

The height of the body is three-fourths of the total length. 



One specimen, 14 inches long, was likewise discovered off the coast of Greenland. 

 Whether some young specimens obtained in Mid-Atlantic, and referred by Liitken to this 

 species, belong to it or to some other species, cannot be decided from the materials at 

 present available.

Head excessively large and broad ; body short. Eyes small. Mouth exceedingly 

 wide and vertical. Jaws armed with bands of teeth unequal in size and depressible ; 

 palate toothless. Skin with scattered, large, round scutes, each ending in a spine. The 

 s^nnous dorsal reduced to a single tentacle ; the soft dorsal and anal very short. Ventrals 

 none. Pectorals well developed. Gills ? 



Unfortunately nothing is known of the gills of this fish, wljidi, as regards grotesqueu ess 

 of form, surpasses the fishes of the preceding genus. It is evidently closely allied to 

 Himantohphus reinhardtii, and I therefore suppose that it possesses the same number 

 (jf gills. If this should prove to be the case, the question will arise whether it should be 

 kept as the type of a distinct genus. According to the figure Aegieonichthys would 

 appear to be much more depressed in shape than Himantolophus ; however, we must 

 remember that these flaccid deep-sea fishes may assume, or l)e made to assume, very 

 different appearances.
