Macrourus holocentrus (Jillirrt i^ Cramer. 



One s))ecinien was taken at station o901J, off the sunth coast of Oahn, 308 to 322 fathoms. 



Heail anil trunk very slender, the head with ronmled outlines and no ridges; lontrituilinal profile 

 of snout eonvex; interorbital space and oceiput eoncave; suli(irl)ital flat, without ridge; spines on scales 

 long, slender and flexible, bristledike, closely crowded, but in rather detinite parallel series, though 

 not borne upon ridges; mi liead and alcjng predorsal area, the spines shorter and frequently in radiating 

 lines; niandil>le naked in tliis specimen ami in one of the cotypes of the species. In the latter there 

 are 8 ventral rays, in the furnier II. 



The following corrections and additions may lie made to tlie original desiTiption: Median rostral 

 tubercle on a level with middle of eye; premaxillaries anteriorly l)elow level of eye; maxillary reach- 

 ing slightly beyond middle of orbit; gill-membranes with a wide free fold where they cross isthmus; 

 serrations of second dorsal spine small, 11 or 12 in number, evenly spaced along entire spine except 

 the filamentous portion; second doi'sal spine very slender; last rays of first dorsal not nearly reaching 

 second dorsal when declined; length of first dori^al base 0.6 the interspace between dorsals; ventral 

 fin, excluding outer filamentous ray, reaching base of second anal ray; back light gray, with some 

 dusky mottlings; lower half of gill-cavity whitish. 



Macrourus huhuvniriis Gilbert & Cramer, Proc. V. S. Nut. .Ntii.-!., XIX, lsy7. -I2.=i, pi. .VLIII. 



Macrourus gibber (iilbcrt i' Cramer. 



Taken at a number of localities but never alimiilantly. The following additions and corrections 

 may lie made to the original description. 



Infraorbital ridge occupying a ver\- oblique pusitiim, but nut ajiproaching the vertical; tip of pre- 

 maxillaries far below level of middle nf eye, their horizontal plane intersecting eye miilvvay between 

 lower margin of pupil and lower margin of orbit; teeth of outer series not enlarged; posterior 

 margin 1 if prenpercle nearly vertical, the angle broadly an<l evenly rounded; gill-membranes with a 

 narrow free posterior margin on middle line lielnw; dorsal jirofile ascending strongly to origin of 

 dorsal, then descending abruptly along base of lin. forming a conspicuous triangular hump; length of 

 jiectorals 0.7 that nf heail; lateral line nearly obsuleti', membranous tubes jn-e.sent on occasional scales 

 or groups of scales nnly. 



Scales (in back and sides thin, deciduous, furnished with very slender, closely ajipressed s]iines, 

 which are arranged in parallel series directed sumewhat obliquely downward and backward; on the 

 liack the series of sjiines may slightly diverge, as given in the figure above cited; sjiines distinct, not 

 located on ridges; on breast and sides of head, the scales are thicker and the .spines stronger, arranged 

 in series which usually diverge; suliocular ridge and the lateral ]iair of rostral ridges covered with 

 very stmngly s]iinous .scales; the 3 rostral tubercles bear msettes of strong spines; spaces between 

 median and lateral rostral ridges naked, nr with a few scattered cycloid scales; lower side of snout 

 and anteriiir half of space between iriouth and subucular ridge naked; mandibles naked, ending 

 posteriorly in a spinous pniiit, which dues imt ]irnject.

 3985, vicinity of Kauai, 433 tti 477 fathoms; 39S9, vicinity of Kauai, 385 to 500 fathoms; .3994, vicinity

 4028, vicinity of Kauai, 444 to 478 fathoms; 4041, off (he west coast of Hawaii, 253 to 382 fathoms; 

 4109, Kaiwi Channel, 442 to 449 fathoms; 4112, Kaiwi Channel, 4.33 to 447 fathoms; 4113, Kaiwi 

 Channel, .395 to 433 fathoms; 4137, vicinity of Kauai, 411 to 471) fathoms; 4139, vicinity of Kauai, 3.39 

 to 512 fathiiins; 4141, vicinity of Kauai, 437 to 632 fathoms: 4166, vicinity of Bird Islanil, 293 to 800 

 fathoms.
