faces, having radiating ridges beset with weak spines; head a little more 

 than of the entire length; snout projecting but little; median and lat- 

 eral tubercles faintly developed; infraorbital narrow, divided into 2 well 

 marked areas, an upper wider, distinguised by the glassy tubercular scales, 

 and the narrow lower, almost skinny and scaleless; the ridge independ- 

 ently, is little marked; teeth biserial in the upper jaw, robust in the 

 outer row, very weak in the inner; uniserial in lower jaw and scarcely 

 incurved; dorsal spine strongly serrate, \\ in head; pectoral 1| in head ; 

 ventrals If in head, with short filaments, reaching vent; interspace 

 between dorsals \ greater than base of first. Bering Sea. Only the type, 

 20 inches long, known, the above description taken from it by us. (subor- 

 Mtalis, pertaining to the region below the eye.) 



Macrurut (Nematonurus) suborbitalis, GILL & TOWNSEND, Proc. Biol. Soc. Wash., xi, 1897 

 (Sept. 17, 1897), 234, Bering Sea, southwest of Pribilof Islands, Albatross 'station

1001. ALBATROSSIA, Jordan & Evermann, new genus. 



Albatrossia, JORDAN & EVERMANN, new genus (pectoralis) . 



This genus has the form and appearance of Chalinura, with the dentition 

 of Nematonurus, and the dorsal spines of Malacocephalus aiid Optonurm; 

 teeth in the upper jaw strong, in an irregular double series, the outer 

 enlarged ; the inner series growing double with age ; lower teeth uniserial 

 or nearly so ; scales small, rather firm, rough ; dorsal spine weak, smooth or 

 very slightly serrate; dorsal fins close together; ventrals well developed; 

 pectorals moderate. Size large. (Named for the good ship Albatross, in 

 remembrance of her splendid contributions to our knowledge of the life of 

 the deep seas. )

Head 6 in total; depth If in head; eye 4 to 5 in head, 1 in snout. 

 D. X-128; A. 121; V. 7; P. 17; mouth wide, lateral, the short snout pro- 

 jecting beyond premaxillaries for a distance about equaling % diameter of 

 orbit; suborbital ridge and lateral ridge on snout inconspicuous; a strong 

 median ridge on snout and a pair of parallel ridges forward from above 

 nostrils ; maxillary reaching well behind vertical from posterior margin 

 of orbit, 2 in head; teeth in 2 somewhat irregular series in front of pre- 

 maxillaries, the outer series enlarged, the inner directed obliquely inward, 

 the two series merging into one laterally; mandible with a single row, 

 similar to inner series of upper jaw ; barbel short, f to y diameter of orbit; 

 angle of preopercle bluntly rounded, not produced; outer gill arch adnate, 

 as usual in Macrourus, 7 short tubercular gill rakers present on its free 

 portion; first dorsal spine slender and weak, with 1 or 2 small retrorse 

 prickles near its middle ; distance between dorsals equal to f base of first ; 

 vent immediately in front of anal origin, its distance from base of ventrals 

 slightly more than head ; pectorals long and narrow, reaching vertical 

 from ninth or tenth ray of second dorsal, more than length of head; 

 outer ventral ray produced into a long slender filament, reaching the
