104 DISCOVERY REPORTS 



Depth of body 9 to 10 in the length, length of head 5! to 6. Diameter of eye about 

 7 in length of head, about equal to interocular width. Maxillary extending to below 

 middle of eye; lower jaw distinctly shorter than upper. 100 to 115 rays in the dorsal 

 fin, 75 to 85 in the anal; distance from head to origin of anal 1^ to i| times length of 

 head. Pectoral about f , pelvic \ to \ the length of head. Body brownish, with a series 

 of pale areas along upper parts of sides, continued on to the dorsal fin ; other irregular 

 pale spots and blotches scattered over lower parts of sides ; abdomen and lower parts 

 of head pale; snout and jaws pale yellowish-white, a sharp line separating this colour 

 from the dark brown of the rest of the head, the latter sometimes projecting below the 

 eye as a short bar ; a pale area on the nape ; pectorals pale, with a large dark area above ; 

 pelvics yellowish.

Hob. Coast of Argentina (?); Patagonian-Falklands region; Tierra del Fuego. 



The above specimens agree very well with Berg's description of Lycodes laticinctus, 

 the type of which was 155 mm. long and came from Santa Cruz. Steindachner's 

 Lycodes platei from the east coast of Tierra del Fuego, the type of which was 234 mm. 

 long, is an undoubted synonym, as is the example from Rio Grande, Tierra del Fuego, 

 described and figured by Smitt (fig. 35) as Phucocoetes variegahis macropiis. The young 

 example, also identified by Smitt as P. variegahis macropus (fig. 36), is, as far as I can 

 judge, a specimen of Iluocoetes fimbriatus. LycodaJepis morenoi, Lahille, was based 

 upon a single large specimen (620 mm.) from Cape San Antonio (36 20' S). The tail 

 appears to be shorter and the coloration somewhat different, but it seems probable that 

 this form represents the same species as that described by Berg. 



Genus Phucocoetes, Jenyns

 P. latitans, Jenyns. 



Some scales embedded in the skin. Head and body compressed. Mouth subterminal ; 

 teeth conical, those of upper jaw uniserial laterally, usually with an outer series of 

 enlarged and canine-like teeth anteriorly, those of lower jaw bi- or triserial ; teeth on 

 the vomer and in a single series on each palatine ; 1 or 2 pairs of teeth in the lower 

 jaw and the middle vomerine teeth more or less enlarged and canine-like. Gill-opening
