øvi'ige Arter, storre. end deres Hojde. og indeholdes 4^^^ — ^ 

 Gange i Hovedlæugdeu. Interorbitalrummet er ganske smalt, 

 men Lindserne store. 



Næseboreue ere enkelte og rorformige ; Tubens Læugde 

 er næsten lig en halv Liiidsedianieter. 



Gjællestraalerne ere hos denne Art blot 5 i Antal. 

 Pseudobrauchier 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. i-errUlii). I Mellemkjæven danne 

 de en enkelt Række af omtrent lO Trender paa hver Side; 

 i Underkjæven iindes hos de mindre Exeniplarer blot en 

 enkelt, hos de større flere Rætker. Mindre Tandsamlinger 

 findes paa A'omer og paa Palatiiibenene. Brekken paa 

 det sidstnævnte Ben er særdeles kort. 



De laugs 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 laugs Overkjæven. 

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

 skaalformige Fordybninger. svarende til Caviteterne i luft-a- 

 orbitalbenene og i Underkjæven. Paa Hovedets Overside, 

 paa Gjællelaageue. s;>mt paa Nakken lindes et stort Antal 

 enkeltstaaende, eller i kortere Rækker fordelte smaa Slim- 

 porer; enkelt? af disse kunne sees at ende i særdeles korte 

 Tuber. 



Anus er længere fremrykket. end hos uogeii af de 

 øvrige Lycoder. eller med andre Ord, Halepartiet er usæd- 

 vanligt langt, ogudgjør omkring ^/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 Luli- 

 vider folgeude (i de verticale Finner ere Caudalstraalerue 

 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'/;, — 0. Interorbital space narrow; lenses large. 



Nostrils single and tul)ular. The length of the tube 

 almost equal to half tlie diameter of the lens. 



Brauchiostegals in this species 5 only. Pseudobranchiæ 

 present; gills normal. 



The teeth, wanting on none of the bones regularly 

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

 ever, than in L. rerriUif), and somewhat cylindrical. On 

 the intermaxillary, they constitute a single sei'ies 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 specimens being all of them relatively 

 young individuals). The 5 extending along the U2iper 

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

 ingly deejj. occupying broad, bowl-shaped depressions 

 corresponding with the cavities in the infraoi'bital bones 

 and in the lower jaw. On the upper surface of the head, 

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

 small mucous jjores. either isolated or arranged in short 

 rows, part of them terminating in exceedingly short tubes. 



The vent is farthei' 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 hn-rays in this species would 

 appear to be an3'thing but constant ; the point, too. at which 

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

 viduals than in others. 



The tin-ray formula in the 4 specimens examined was 

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