Det linieformige Lnfraorbitalben er 



normalt udviklet. 



Orbitae ere forholdsvis store, med Højdediameteren 

 abetydeligt kortere, end Længden; den sidste indeboldes i 

 Eovedlængden næsten 3 l /' a Gange. Enterorbitalrummet er 

 rladt eller svagt convext, og aæsten lig Hovedets halve 

 Længde. (Øjnene ere. som ovenfor nævnt, hos det under- 

 søgte Individ udfaldne). 



Tænderne ere tilstede i Mellemkjæverne og i Under- 

 kjæven. De ere yderst fine, og ordnede i regelmæssige, 

 skraatløbende Tverrækker; fortil i Underkjæven tindes om- 

 trent- 10 Tænder i hver saadan Række. 



Skulderbeltet ender oventil i en temmelig. spids Torn, 

 der maaske hos det uskadte Individ har vist sig som en 

 lav Kunde over Nakken. Det til den indre Rand af Cora- 

 coidbenet fæstede ribbenformede Benstykke (Atlas's Hæma- 

 pophyse-Del) er elter sin hele Liængde smalt, særdeles langi 

 og spidst, og strækker sig lige ned mod Bugranden, uden 

 dog at danne nogen lukket Bue med det tilsvarende paa 

 den anden Side. 



Anus's Beliggenhed kan. som tidligere nævnt, ikke med 

 fuld Sikkerhed augives. da individet er skadet i Bugen. 

 Dog er det sandsynligt, at det har ligget temmelig mer 

 Analen, idet et forholdsvis langt Parti bagenfor (den mang- 

 lende) Sugeskive er helt, og uden at vise Spor af Anal- 

 aahning. 



Sugeskiven er, som ovenfor nævnt, afreven. Dog 

 antydes dens Beliggenhed ved et Hul paa Bugen noget 

 bagenfor de nedre Pectoralstraaler. Skiven har ikke været 

 særdeles langt fremrykket (saaledes som hos Slægten Gare* 

 prootus), men den nævnte Aabning er forholdsvis liden, og 

 synes at antyde, at det samme har været Tilfældet med 

 Sugeskiven. 



Finnerne. Dorsalen begynder lige bagenfor Nakken: 

 dens Afstand fra Snudespidsen indeholdes hæsten 5 Gange 

 i Totall. De forreste Straaler ere ufuldkomne Pigstraaler, 

 og særdeles korte og svage,, samt have Ansats til at være 

 dobbelte nedtil. Omtrent fra den 7de Straale af ere de 

 alle kiøvede til Grunden, eller fuldkommen dobbelte, samt 

 tydeligt articulerede etter hele sin Længde; midt paa Ryg- 

 gen er Mellemrummet mellem liver Straales Halvdele saa 

 distinct, at de næsten synes at være stillede parvis. Den 

 største Hojde har Finnen paa Midten af Halepartiet, hvor 

 Stsaalerne have en Længde, der er lig Hovedets Længde 

 indtil Øjets Bagrand; dog har sandsynligvis aldrig Finnen 

 kunnet hæve sig til. denne Hojde. Bagtil aftage" Straalerne 

 kun ubetydeMgt i Hojde. og de ere ved Haleroden etter 

 hele sin Længde tilvoxede Oaudalen, samt ere her tættere 

 stillede. end længere fortil. Straalernes Anta] er 59, et 

 Tal der ikke er naaet hos nogen hidtil nøjagtigt undersøgt 

 Art af Liparidernes Familie. 



Analen. der tæller 51 Straaler, er i Bygning temme- 

 lig overensstemmende med Dorsalen, og begynder, (som hos

■ Vjy. the linear infraorbital hone normally developed. 



Orbitæ comparatively large, the vertical diameter 



somewhat less than the transverse: the latter is to the 



length of the head as 1 to ■'!' _• almost. LnterorbitaJ sur- 

 face Hal or slightly convex, width nearly equal to halt the 

 length ol' the head. (In the specimen examined both the 

 eyes were gone). 



Teeth in intermaxillaries and in 'lower jaw: they are 

 exceedingly slender and minute, regularly arranged in 

 oblique transverse rows: each row in the anterior part of 

 lower jaw composed of about in teeth. 



The scapulary arch terminates above in a rather 

 sharp-pointed spine, which, in specimens not mutilated per- 

 haps would appear as a depressed protuberance on the 

 nape. The costal-shaped hone (the hæmapophysis ol' Atlas) 

 attached to the inner margin of the coracoid is narrow- 

 throughout its entire length, and very long and sharp at 

 the point, extending straight down to the margin of the 

 abdomen, without however meeting that on the opposite 

 side and forming 8 perfect arch with it. 



As before observed, the exact position of the vent 

 cannot he given, the specimen examined having been muti- 

 lated in the abdominal region. Probably, however, it is in 

 close proximity to the anal tin. a. comparatively extensive 

 portion of the surface posterior to the ventral-disk (wanting 

 in this individual) exhibiting no vestige whatever of an 

 anus. 



The ventral disk, as mentioned above, had been torn 

 oil'. Its position however was clearly indicated by an 

 oritice in the abdominal surface somewhat posterior to the 

 lower pectoral rays. The disk cannot therefore have been 

 very far back (as in the genus Ccweprodus) ; hut the said 

 oritice was comparatively small, denoting apparently that 

 such, too, is the case with the ventral disk. 



Fins. — Dorsal commencing in close proximity to 

 the nape; its distance from tip of snout is to total length 

 nearly as 1 to 5. The foremost rays spinous, but exceed- 

 ingly short and fragile, towards the base inclining to branch. 

 From the 7th ray about, they are all of them double, being cleft 

 "to the base, and distinctly articulated throughout their entire 

 length: in the middle of the back the interspace between 

 the halves of each ray is so conspicuous as almost to give 

 these rays the appearance of being arranged in pairs. 

 Greatest depth of the fin in the middle of the tail, where 

 the length of the 'rays equals the length of the head 

 measured to the posterior margin of the eve: it is notpro- 

 bable however that the tin can lie elevated to that extent. 

 The posterior rays, which diminish but slightly in height, are 

 at the base of the tail attached to the caudal throughout 

 their entire length; these terminal rays, too, are more 

 closely arranged. Number of rays 59, — hence exceeding 

 that in any accurately determined species of the family 

 Liparidiclæ. 



The anal, furnished with 51 rays, very similar in 

 structure to the' dorsal, having at the commencement (as
