ing under posterior margin of pupil. Teeth in a narrow band in each 

 jaw, some of those at least in outer row of upper jaw slightly enlarged 

 and brownish colored; teeth of vomer forming a short curved band in 2 

 rows. Nasal barbel about equaling diameter of eye. Chin barbel small 

 and not much exceeding diameter of eye. Foremost ray of first dorsal 

 springing from back above opercular margin ; second dorsal fin low in 

 front, but rising rapidly to seventh or eighth ray, behind which it is 

 nearly uniform for a long distance, and the highest at posterior portion; 

 anal fin much lower than second dorsal; caudal slightly emarginate, 

 almost truncate behind, its median rays about as long as head; pecto- 

 rals nearly f as long as head, produced toward the upper angles, the third 

 ray being longest; ventral fins with their bases mostly in advance of pec- 

 torals, the longest ray filamentous and nearly equaling pectoral. Lateral 

 line obsolescent. (Goode & Bean.) Atlantic coast of North America, 

 from Greenland to Cape Hatteras; in deep waters, reaching a depth in 

 the Gulf Stream of 1,081 fathoms, (emis, sword.)

2934. GAIDROPSARUS ARGENTATUS (Reinhardt). 



Head 5 ; depth 5f. D. 54 to 59 ; A. 45 or 46. Body elongate ; head small ; 

 teeth in several rows, 1 row more enlarged than the others; maxillary 

 reaching posterior border of eye; eye large, 5| in head; interorbital space 

 scarcely exceeding the eye. Lateral line with about 27 enlarged pores 

 along its entire length. First ray of first dorsal short, little longer than 

 snout; vent near middle of length. Reddish gray, changing to bluish on 

 the head and abdomen ; tips of dorsal, anal, and caudal red, also the bar- 

 bels and first ray of first dorsal; cavity of mouth pale. Coasts of Green- 

 land (Collett), south to Faroe and Bear Islands; not seen by us. There 

 can be no doubt that Motella argentata is the young of the species later 

 called Motella reinhardti. (Eu.) (argentatus, silvered.)
