No visible scales. Depth of body 7J to 9! in the length, length of head 5I to 6. 

 Diameter of eye 6 to 7 in length of head, about equal to interocular width, greater than 

 interorbital width. Maxillary extending to below posterior part or hinder edge of eye ; 

 lower jaw shorter than upper; teeth obtusely conical, those of upper jaw uniserial 

 laterally, bi- or triserial anteriorly, those of lower jaw uniserial, with an inner series 

 of 2 to 4 teeth at the symphysis; no canines in upper jaw, but 1 or 2 teeth on each side 

 of lower jaw enlarged and canine-like ; 2 or 3 teeth on the vomer and a single series on 

 each palatine. About 85 rays in the dorsal fin, about 70 in the anal ; distance from head

to origin of anal about ij times length of head. Pectoral about f, pelvic \ to \ the 

 length of head. Head, body and fins variegated with dark brown ; body with a series 

 of more or less distinct broad dark cross-bars; pectoral spotted and blotched with 

 darker. 



Hab. Patagonian-Falklands region. 



This species, which was not previously represented in the British Museum collection, 

 is readily distinguished from the preceding by the absence of scales, the smaller head, 

 smaller eye, absence of canine teeth in the upper jaw, greater distance from the head to 

 the origin of the anal fin, and by the coloration. 



Genus Austrolycus, Regan 

 1913, Trans. R. Soc. Edinb., xlix, p. 245. Type A. depressiceps, Regan. 

 Some scales embedded in the skin. Head depressed ; body compressed posteriorly. 

 Mouth subterminal; teeth conical, uniserial at sides of jaws, bi- or triserial anteriorly; 

 a group of teeth on the vomer and a single series on each palatine. Gill-opening cleft 

 downward to middle or lower part of base of pectoral. Dorsal origin just behind head, 

 above base of pectoral ; pelvic fins present. 

 Two species.
