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; uuiserial in lower jaw and scarcely 

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

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

 between dorsals 4^ greater than base of first. Bering Sea. Only the type,

looi. ALBATROSSIA, Jordan & Evermann, new genus. 



Albatrossia, Jordan & Evermann, new genus (pectoralis) . 



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

 of Xcmatonunts, and the dorsal spines of Malacocephalns and Optonurus; 

 teeth in the upi)er jaw strong, in an irregular double series, the outer 

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

 ornearly 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. )

 jecting beyond premaxillaries for a distance about equaling I 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, 5 to f diameter of orbit ; 

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

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

 I)ortion; first dorsal spine slender and weak, with 1 or 2 small n^trorse 

 prickles near its middle; distance l)etween 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
