øvrige Arter, større, end deres Højde, .og indeholdes 4^ — 5 

 Gange i Hovedlængden. Interorbitalrummet er ganske smalt, 

 men Lindserne store. 



Næseborene ere enkelte og rørformige ; Tubens Længde 

 er næsten lig en halv Lindsediameter. 



Gjællestraalerne ere hos denne Art blot 5 i Antal. 

 Pseudobranchier ere tilstede: Gjællerne ere normale. 



Tænderne. der ikke mangle paa noget af de regulært 

 tandbærende Ben. ere forholdsvis lange og noget cylindriske. 

 (dog kortere, end hos L. verrillii). I Méllémkjæven danne 

 de en enkelt Række af omtrent 1 Tænder paa hver Side ; 

 i Underkjæven tindes hos de mindre Exempkirer blot en 

 enkelt, hos de større flere Rækker. Mindre Tandsamlinger 

 tindes paa. Vomer og paa Palatinbenene. Rækken Jpaa 

 det sidstnævnte Ben er særdeles kort. 



De langs Over- og Underkjæven optrædende store og 

 aabne Porer ere hos ingen anden Art saa distincte. som 

 hos denne (maaske. fordi disse Individer samtlige ere for- 

 holdsvis ganske unge). Især ere de - 5 langs Overkjæven. 

 og de 6 langs Underkjæven særdeles dybe. og sidde i brede, 

 skaalformige Fordybninger. svarende til Caviteterne i Infra- 

 orbitalbenene og i Underkjæven. Paa Hovedets Overside, 

 paa Gjællelaagene. samt paa Nakken nudes et stort Antal 

 enkeltstaaende. eller i kortere Rækker fordelte smaa Slim- 

 porer : enkelte af disse kunne sees at ende i særdeles korte 

 Tuber. 



Anus er længere fremrykket. end hos nogen a f de 

 øvrige Lycoder. eller med andre Ord. Halepartiet er Jusæd- 

 vauligt' langt, og udgjør omkring. 3 / 4 af Totallængden. 



Finnerne. Straaleantallet synes hos denne Art at 

 være særdeles lidet constant, ligesom det Punkt, hvor Dor- 

 salen tager sin Begyndelse, kan være forholdsvis længere 

 fremrykket hos et Indidid. end hos et andet. 



Antallet af Straaler var hos de 4 foreliggende Indi- 

 vider følgende (i de verticale Finner ere Caudalstraalerne 

 medregnede) • 



both in this and in the other species, is greater than the 

 vertical, and compared to the length of the head, as 1 

 to 4 1 /a — 5. Interorbital space narrow ; lenses large. 



Nostrils single and tubular. The length of the tube 

 almos't equal to half the diameter of the lens. 



Branchiostegals in tliis species 5 only. Pseudobranchia? 

 jiresent; gills normal. 



The teeth, wanting on none of the bones regularly 

 furnished with them, are comparatively long (shorter, how- 

 ever, than in L. rrrrilli-i), and somewhat cylindrical. On 

 the intermaxillary, they constitute a single series of about 

 10 teeth on each side; in the lower jaw. the smaller examp- 

 les have only a single row. the larger several series. Small 

 patches of teeth occur on the vomer and the palatine bones ; 

 ,the series on the latter is exceedingly short. 



The large pores disposed along the upper and lower 

 jaws are in none of the other species so distinct as in this ' 

 (possibly from the sjæcimens being all of them relatively 

 young, individuals). The 5 extending . along the upper 

 jaw, and the 6 along the lower, are in particular exceed- 

 ingly deep, occupying broad, bowl- shaped depressions 

 corresponding with the cavities in the infraorbital bones 

 and in the lower jaw. On the. upper surface of the bead. 

 on the opercles. and on the nape, are a large number of 

 small mucous pores, either isolated or arranged in short 

 rows, part of them terminating in exceedingly short tubes. 



The vent is farther in advance than in any of the 

 other Lycods; hence the caudal region is exceptionally 

 long, well nigh three-fourths of the total length. 



Fins. — The number of fin-rays in this species would 

 appear to be anything but constant ; the point, too, at which 

 the dorsal commences, lies farther in advance in some indi- 

 viduals than in others. 



The fin-ray formula in the 4 specimens examined was 

 as follows (caudal rays included in the vertical tins): —
