ghssMs (hans senere pingius) som identisk med Linnes Pl. 

 cynoglossus. eu Anskuelse, som gjendreves af Glill allerede 

 i 1804 (Troe. .Acad. Nat. Sei. Pliilad. 1864). Gunther 

 havde imidlertid givet Arten, der efterhaanden ogsaa gjen- 

 dem andre var bleveiT bekjendt, det .nye Navn Hippoyhsms 

 groenJandiais, hvorhos ^ahricii Fl. hippoglassus opføres som 

 dens Synonym; dette sidste var imidlertid ucorrect. da Pl. 

 hippofflossus-, abr., utvivlsomt er den rette iZ/j;jJO(/L ridgaris. 



Navnet Hippoglosms pinguis (Fabr.), under hvilket Ar- 

 ten oftest er omtalt, er yngre, end Walbaums Pleuromxtes 

 hippoglossoidcs (1792), der saaledes indeholder det ældste 

 Artsnavn. 



Da lorhaandenværende Art i flere Henseender ad- 

 skiller sig. fra Slægteu Hippoglossus , med hvilken, den i 

 Regelfen er slaaet sammen, har Gill allerede 11861 henført 

 deu under en ny Slægt, ReinhardHns (Proc. Acad. Nat. 

 Sei. Philad. 1861, App.), men da denne Slægt her., udeu 

 at være charaeteriseret, blot er- nævut i en Fortegnelse, 

 vil Bleeker's Na vu Platysomatichihgs, opstillet i 1862 for 

 den samme Art (13de Bind af Med. Kon. Akad. VVet. i 

 Amsterdam). l)live at anvende. 



Bemærkninger til Beskrivelsen. Det under Nord- 

 havs-Expeditionen eriioldte Individ var yngre, og. havde føl- 

 gende Maal: . • • 



Totallæ|igde . .' 435'""' 



Legemets Længde til sidste Halehvir^el .... 378 - 



Legemets Hojde 12(1 - 



Halerodeus Højde . . . ' 34 - 



■ Ho vedets Længde ' . . 104 - 



Pectoralens Længde paa Blindsiden _. . 4U - 



Tæuderne hos dette Individ vare paaØjensideu oven- 

 til 15, hvoraf de inderste vare riieget smaa. nedentil 7. gille 

 lange og uaalspidse. Paa Blindsiden fandtes oventil 2'2, * 

 nedentil 6. samtlige af samine Bygning, som tie tilsvarende 

 paa .Øjeusiden. 



Straaleantallet var: D. 92; A. 71; 0. 2<^)\ V. .6; 

 P. 14. 



Farven paa Blindsiden var kun lidet TysereJ end Øjen- 

 sidens. 



Interorbitalrummet var hos dette yngre Individ for- 

 holdsvis suialt, sammenlignet med Øjuenes Størrelse; dets 

 Bredde var omtrent, som Øjets Tverdiameter, men, mindre, 

 end Lanigdediametereu. 



Udbredelse. PhdyxomaticJdJii/s h/ppoglossoides er en 

 arctisk Art, der tidligst har været kjendt fra Grønland, 

 hvor den allerede er beskreven i 1780 af Fabricius; den 

 synefe her at ■ være talrig paa det noget dybere Vand. • Mod 

 Syd gaar den. i Nordåmerica- (ifølge Goode & Beau) lige 

 ried til Dybderne udeufor Essex og Massachusetts i New 

 England-Staterne (420 ]sf. B.). 



I de europæiske Farvande har den hidtil blot været 

 omtalt fra Finmarken, hVor enkelte Exemplarer i dé- senere 

 Aar ere fundne og opbevarede, men neppe søndenfor 70" 



to regard Fabricii Pl. cynoglossns (subsequently pinguis) 

 as identical with Linupus's Pl. cynoglossus, an assumption 

 confuted by Gill in 1864 (Proc. Aeåd. Nat. Sei, Philad. 

 1864). Gunther, however, had giveii the species (which had 

 • meanwhile been also recorded by others) the new name, 

 Hippoglossus grænlarulicns, regarding Fabrieius's PI. hippoglos- 

 sus as its synonym ; but the latter was erroneous, and PI. hip- 

 poglossus Fabr. is unquestionably the true Hippogl. rulgaris. 



Hippoglossus pinguis^ (Fa.br.). the name under which 

 this species has been most fre('|uently mentioned, is antici- 

 pated by Walbaum's Ph-uronecfes liippoglossoides {ll\)2). the 

 earliest specific designation of the fish. 



The species described being in several respects es- 

 sentially distinct from the genus Hippoglossus, to which 

 it has generally been r.eferred. Dr. Gill, so far • back as 

 1861. saw 'fit to ■ class it as the type of a new genils, 

 Eeinhardtius (Proe. Acad. Nat. Sci. Philad. 1861,, App.); 

 but the name of this genus being merely recorded in a Cata- 

 logue, and no characters, enumerated, Platysomatichthys, 

 established' by Bleeker in 1862 for the same type (Med. 

 ■ Kon. Akad. Wet. Amsterdam.' D. 18), mtfst be the. correct 

 designation. 



Despriptive Observations. * — The individual obtained 

 on the Expedition was comparatively young, and measured 

 as follows : — ' • ' 



.Total* length' . . ..... 435""" 



Length of body to last caudal vertebra, .... 378 - 

 Depth of body.' . . '. . . . ... . . . 120 - 



Depth of tail at base 34 - 



.Length of head " 104 - 



. Length of jJectqral on blind side 40 - 



The teeth on the coloured side, above, in tliis indiv- 

 idual 15, the innermost exceedingly small; below 7, all 

 long and acicular; on the blind' side the number above was 

 22, below 6, similar in structure to ■ those corresponding 

 with them on the coloured side. 



The fin-ray formula was as follows: — D. 92; A. 71 ; 

 C. 20; Y. 6: P. 14. ' 



The colour of the skin on the blind side but a shade 

 ■lighter than on the upper. 



Interorbital space iu this immature example rather 

 narrow compared to the eyes, its width being about equal 

 to the vertical diameter of the orbit, but less than the 

 longitudhial diameter. 



Distribution. — Phdysoviaticldhys hippoglossoides is 

 an Arctic species, first observed on the coast of Gi'eenlaiid, 

 and described, so far back as 1 780, by Fabricius ; through- 

 out that region it would appear to be a comriion fish at 

 some depth. In North America its range southwards 

 (according to Goode & Beau) extends to the depths lying 

 off the shores of Essex and Massachusetts,, in New England 

 ." (in lat. 42" N.). 



In the regions of Northern Europe, the sjjecies had 

 been previously met with on the coast of Finmark only, 

 where examples haye in later years, been taken and pre-
