JORDAN AND THOMPSON: FISHES OBTAINED IN JAPAN IN 1911. 305 



Family MACROURID^. 

 358. Coryphaenoides bona-nox sp. nov. (Plate XXXVIII, figs. 1 & la). 



The type is a single large example from Sagami Bay, three hundred milli- 

 meters long, No. 6462 Carnegie Museum Catalog of Fishes. 



Head 4 in length without caudal; depth 5 (1.2 in head); snout 3.6 in head; eye 

 4; maxillary 2.4; D. II, 9, 84; A. 78; P. 19; scales 125, between first dorsal spine and 

 lateral line 8. 



Snout slightly longer than eye, firm in texture, especially at apex and lateral 

 angles; maxillary reaching almost to below posterior margin of eye; profile of head 

 evenly arched from dorsal, save slight flat area above ej^es; interorbital space nearly 

 as wide as eye, flat; pre-orbital convex, forming a low, rounded ridge with side of 

 snout, not, however, sharply dividing head into upper and lower parts; snout 

 projecting over premaxillaries a distance equal to two-thirds diameter of eye; 

 teeth in narrow bands in both jaws; two or three series of small, rather blunt teeth 

 anteriorly, dwindling to a single one posteriorly, outer teeth not enlarged; mandi- 

 bular barbel half diameter of eye ; first branchial arch with fold of membrane crossing 

 it, attaching it to opercular wall; anterior gill-slit two-thirds of diameter of eye in 

 length; five gill-rakers, tubercle-like; anus as far behind ventral base as postorbital 

 length of head. 



Dorsal inserted over pectoral base, which is over that of ventrals; second spine 

 not filamentous, its length contained twice in head, its lower half smooth, its upper 

 half with six or seven coarse spinules ; second dorsal inserted behind first, a distance 

 equal to length of base of latter and before anus; first ray of second dorsal 3.5 in 

 base of first; anal inserted under fifth ray of second dorsal, anus immediately 

 preceding; ventrals filamentous, longest ray 1.75 in head, reaching anus; pectorals 

 1.75 in head, not filamentous. 



Scales hard to the touch, with six to eight strong radiating ridges, their spinules 

 closely imbricate and each closely applied to that following, the last spinule pro- 

 jecting beyond scale-border in each ridge; scales on suborbital and snout with greatly 

 thickened, bony ridges, frequently but one or two in number; scales present every- 

 where on head and body save lips and throat; no scaleless area between ventrals. 



Color uniformly dark brown; all fins very dark. 



The dentition and scales of this species distinguish it from previously known 

 forms. 



The senior author has studied the fishes of America and of the world for over 

 forty years. His attention is now turning from Ichthyology and Taxonomy to 

 larger but less charming studies in the relations of nations. This is, no doubt, the
