Neoscopelus macrolepidotus (.lohnson). 



No Allantic material has been at hand for comparison, but a single specimen from .lapan'* seeiris to 

 to agree completely with the Hawaiian specimens. No individuals were taken at the surface, but it is 

 jierhaps doubtful whether the following stations, taken with other recorded depths, can be accepted as 

 giving the vi'rtical range of a bottom form : Nos. 3824, off the south coast of Molokai, 222 to 498 fathoms; 

 3892, off the north coast of Molokai, 328 to 414 fathoms; 3973, vicinity of French Frigate Shoals, 395 

 to 397 fathoms; 3979, vicinity of Bird Island, 222 to 387 fathoms; .3994, vicinity of Kauai, 330 to 382 

 fathoms; 4014, vicinity of Kauai, .362 to .399 fathoms; 4021, vicinity of Kauai, 28(5 to .399 fathoms; 

 4025, vicinity of Kauai, 275 to 368 fathoms; 4041, off the west coast of Hawaii, 253 to 382 fathoms; 

 4137, vicinity of Kauai, 411 to 476 fathoms; 4166, vicinity of Bird Island, 293 to 800 fathoms. 



Family M.\UROLICII).€. 



Argyripnus ejihippiatus ( iilbert & Cramer. 



Three specimens were obtained at the following stations: Nos. 4085, off the nortli coast of Maui, 267 

 to 283 fathoms; 4121, off the northwest coast of Oalui, 216 to 251 fathoms. 



The species has been referred by Garman (Mem. Mus. Comp. Zool., XXIV, l.S9<), ]i. .399) to the 

 genus ValencienneUus Jordan and Evermann. it <liffers, however, in the much more anterior position 

 of the dorsal fin in comparison with the anal, and in the widely divergent arrangement of the photo- 

 phores. An adipose dorsal is well develo]icd, a character which escaped attention in the type owing 

 to mutilation.

Argyropelecus heathi, new species. Plate 72, fig. 1. 



Type, 31 mm. long, from station 4107, Kaiwi Cbannel, between Oahu and Molokai, depth .3.50 to 

 3.55 fathoms; type. No 516.32, U. S. Nat. i\Ius. 



Head 3.5 in length to base of caudal; depth 1.9. I), vii-^8; A. 11 ''; P. 9. Depth of body less 

 than in other species of the genus, containecl 1.3 in length of trunk and tail; camlal iicdunde very 

 slender, its least depth but half its length jioslerior to last anal ray; eyes lateral in position btU dire<-ted 

 vertically upward, separated by a very narrow ridge; longitudinal diameter of eye 0.3 the length of 

 the head; exjwsed portion vertically oltli.mg in sliajie, the vertical diameter being half greater than 

 the horizontal; pupil confined to extreme ui)i)er half of exposed area. 



Cleft of mouth nearly vertical; when clo.sed the mandible fits within the ujiikt jaw; mandibular 

 symphysis with a scarcely noticeable prominence; length of maxillary contained 1.2 times in head, 

 premaxillary lying along the anterior margin of its proximal half; premaxillary teet h nunute, in a single 

 series, the lateral teeth directed toward angle of month; lieyond end of premaxillary bone, the maxil- 

 lary is provided with a single series of similar tei'th, all or nearly all retrorsely set; mandibular series 

 with slightly larger hooked teeth, in a narrow patch at symphysis, a single series laterally; no teeth 

 <-an be detected on the vomer or palatine bones; gill-membranes widely joined, free from isthnms; 

 branchiostegal rays 9; gill-rakers long and slender, 6 ; 12 on the outer arch; p.seudobranchia' well 

 developed; the preopercular angle bears 2 large spines, the longer one directed vertically downward, 

 the other obliquely upward and backwaril; the angular bears a short triangular spine, and the i-lavi<-u- 

 lar symphysis a similar larger spine; the abdominal crest, between ventral and pectoral fins, formed bv 

 the union of 12 pairs of plates, each of which covers a luminous organ, the plates without ridges, serra- 

 tions or spines; posteriori)', for a space corresponding to the last 3 plates, the crest is formed by a very 

 thin bony lamella derived from the pelvic girdle, this plate increasing in height posteriorly and termi- 



aSince tlie above was written, the Japanese specimen referred to has been made the type of a. new species. Is', alcacki 

 .Tordan A Starlis (Bull. U. S. Fish Com. lor 1902, S80, pi. 2, figs. 1 and 2), lint as no direct comparison has been made with 

 Atlantic material, the name is not adopted ni this paper. 



^A wider interspace In the middle of the series apparently indicates the loss of a ray, thus making 12 ni all.
