2. BATHYGADUS GARRETTI, new species. 

 Plate 8, fig. 1. 



Bathygadus garretti differs from the type description of the 

 related species, B. nipponicus,^ in the presence of a small barbel; in 

 the more numerous gill-rakers, 18 or 19 instead of IG, on the lower 

 limb of the outer arch ; in the narrower interorbital, 4 instead of 3.13 

 in head ; in the smaller orbit, 4.7 instead of 4.2 ; in the whitish color 

 of the second dorsal fin anteriorly; in the fewer dorsal rays, II, 

 9 instead of II, 10; and in the more numerous ventral rays, 10 or 11 

 instead of 9. It differs widely from the remaining species of 

 Bathygadus with comparatively firm heads, from B. iimcTops^ in 

 the much smaller eye, coarser teeth, and darker color ; from B. fla- 

 mento8us^ in the much larger eye, narrower interorbital, firmer head, 

 absence of long fin filaments, lighter color, and the presence of a 

 barbel; and from B. sulcatus^ (which it closely resembles) in the 

 wider interorbital, lighter color, and lower curve in the lateral line. 



Type-specimen. — Cat. No. 76863, U.S.N.M.; length 513 mm., 176 

 mm. to anus; from Alhatross station 5059, at a depth of 197-297 

 fathom, in Suruga Gulf. 



Dorsal, II, 9; ventral, 10; pectoral, 17. 



Dorsal and ventral contours about equally curved; snout, near 

 axis of body, angulated at the upper end of the premaxillary spine ; 

 head and trunk wdth subvertical sides; the width of the body over 

 the pectoral bases about equal to the postorbital length of tlie head, 

 and about three-fourths the vertical depth of the body ; width of the 

 tail twice the length of the head behind tip of snout, 2| in the depth 

 at that vertical. 



Head comparatively firm, about as in Gadomus nwltiflis^ its 

 length 4.9 in the total length (the tail entire). Orbit 4.7 in head, 

 1.2 in the bony interorbital width, which is contained 4 times in the 

 head; length of snout 3.5; least width of suborbital 1.9 in orbit; 

 the thin suborbital ridge little oblique, and not prominent. Opercle 

 with two weak, divergent ridges, the upper one ending in a weak 

 flat spine; margin of interopercle produced backward at its upper 

 angle in the form of a rounded IoIdc, visible behind the margin of 

 the preopercle, which forms a semicircular curve. Mouth terminal, 

 little oblique; maxillary 1.9 in head, extending past vertical from
