Beskrivelse. Legemsbygning. Legemets Højde over 

 Nakken indeholdes hos alle de erholdte Individer omtrent 

 11 Gange i Totaliængden ; bagenfor Nakken er Legemet 

 jevnhøjt indtil Anus. idler hæver sig ganske ubetydelig!. 

 især hos enkelte mindre Individer, indtil Begyndelsen af 

 Dorsalen. 



Anus er beliggende forholdsvis langt. tilbage, saaledes, 

 at Legemets Længde loran Anus forholder sig til Partiet 

 hag Anus (Halen), sum 1 til 1.4. 



Hovedet ér relativt noget mindre hos de udvoxede 

 Individer, end hos de yngre; .hos de sidste indeholdes det 

 5,2 til 5.4 i Totaliængden, hos de ældre 5,5 til 5,9, eller 

 endog 6 Gange i denne. Kjæverne ere omtrent lige lange- 

 fortil, og naa tilbage til' Øjets. forreste Rand. 



Øjnene ere temmelig tætstaaende og store, samt hen- 

 gere end Snuden, og. indeholdes S 1 /^ til 4 Gange i Hoved- 

 hengden. Næseborene ere 1 Par. endende i korte Tuber; 

 i Nærheden af hvert af dem tindes en større Pore. der 

 maaske kunne opfattes som et andet Par Næsebor. 



Gjællespalten er vid, og naar nedtil frem under Mid- 

 ten af Øjet (saaledes hengere frem. end hos de øvrige 

 Lumpener). GjæUehinderné, der have hver 6 Straaler, ere 

 nedtil sammenstødendé, ilden egentlig at danne nogen fri 

 Fold paa Struben, 



Tænderne. der ere tilstede i Kjæverne og paa Pala- 

 tinbenene, ere samtlige smaa og svage: hos alle N.ordhavs- 

 Expeditionens yngre Individer ere Tænderne paa disse sidste 

 Ben endnu umærkelige. og selv hos det største ere de sær- 

 deles svage, skjønt fuldt udviklede. 



Finnerne. Straaleantallet viste sig idethele temmelig 

 constant hos de erholdte Individer.

General Description. Structure of the Hotly. — Depth 

 of body at nape, in all the specimens obtained, is to total 

 length about as 1 to 11; posterior to the nuchal region, 

 the depth continues uniform as far as the vent. or. in. 

 the smaller examples, slightly increases up to the commence- 

 ment of the dorsal. 



The -vent placed comparatively far hack, the length 

 of the body anterior to the orifice being to the length of 

 the postanal region (the tail) as 1" to 1.4. 



Head somewhat smaller in adults than in young 

 examples: in the latter, the length is to the total length as 

 1 to 5.2—5.4; in the former, as 1 to 5.5 — 5.9 (or even 6). 

 .laws about equal in length, reaching back to the anterior 

 margin of the eye. 



Eyes rather close and large; their longitudinal diame- 

 ter, exceeding the length of snout, is to length of head as 

 1 to 3 1 /.' — 4. Nostrils — one pair only - terminating in 

 short tubes; in close proximity to each -occurs a large 

 pore, which, perhaps, may be regarded as forming together 

 a second "pair of nostsils. 



Branchial opening wide, extending forwards under 

 the middle of the eye (farther accordingly than in any 

 of the other Ltimpenus species). Branchipstegous mem- 

 bra nes. each furnished with 6 rays, contiguous on the isthmus, 

 without however producing a free fold on the throat. 



Teeth, small and feeble, in the jaws and on the 

 palatine bones. In all the younger examples taken on 

 the Expedition, the palatine teeth were as yet obsolete, 

 and in the largest even, exceedingly feeble, though fully 

 developed. 



Fins. — The number of tin-rays was comparatively 

 constant in all the specimens obtained.
