Bemærkninger til Synonymien. Som det under 

 foregaaende Art er nævnt. fandt allerede Prof. Reinhardt 

 (sen.) i 1838 det hensigtsmæssigt at henføre denne Art, der 

 i Modsætning til de øvrige Lumpener besad Tænder (foru- 

 den i Kjåeverne) tillige paa Palatinbenene og paa Vomer, 

 under en egen Afdeling. der blot indbefattede denne Art. 

 For denne foreslog Nilsson i 1855 i sin Skand. Fauna 

 Navnet Ctenodon. .Men da dette Navn allerede i 1830 var 

 benyttet af Wagler for et Eeptil (Fam. Ameividae), i 1838 

 af Ehrenberg for en Infusorie (Rotatoria ), og i 1839 af 

 Swaiuson for en Fisk. bliver Navnet Leptoclinus. fremsat af 

 (iill i 1861. men forst i 1864 characteriseret, at anvende 

 for denne Underslægt. 



Mellem den Reinhardtske L. aculeatus fra Spitsber- 

 gen, og Fries's Art L. mandatas fra Bohuslen, kan der 

 ikke paavises nogensomhelst Forskjel.' Jeg har noje sam- 

 menlignet det forhaandenværende Individ fra Spitsbergen 

 med andre fra Christianiafjorden og Bohuslen, og fineler 

 dem i alle Henseender overensstemmende. Straaleantallet 

 er gjennemsnitligt det samme; det under Nordhavs-Expedi- 

 tionen erholdte Individ havde D. 61; A. 37; P. 15 — 15, 

 medens et andet Individ fra Isfjorden paa Spitsbergen, som 

 jeg har havt til Undersogelse fra Tromso Musauim. havde 

 i Dorsalen 59. i Analen 35, saaledes at Tallet synes at 

 variere. 2 Exemplarer fra Christianiafjorden havde begge 

 i Dorsalen 58, i Analen 36 Straaler. 



At Fries's Navii maculatus ved Spørgsmaalet om 

 Prioriteten bliver at anvende, kan ne])pe ansees for tvivl- 

 somt. Det Bind af det D. Vidensk. Selsk. Forh. ( 6te Del), 

 hvori Beinhardt opstillede sin Ltlmpenus aculeatus. udkom 

 i 1837, samme Aar, som Fries- i Kgl. Vet. Akad. Handl, 

 udførligt beskrev sin' Vliuus maculatus fra Bohuslen. Men 

 uagtet Beinhardt allerede havde omtalt sin Art under Navn

 the caudal region as 1 to 1.3. Colour yellowish, the back 

 marked with 5 large broumish transverse sixjts ; the intervals 

 filled up with smaller and Jess distinct spots, in some examp-

 stronger teeth than the females. Length reaching 180 '"""■

Remarks on the Synonymy. — As previously stated, 

 in connexion with the foregoing species. Prof. Beinhardt 

 sen., so far back as 1838. saw tit to class L. maculatus, 

 which, unlike the other species, is furnished with teeth on 

 the vomer and the palatine bones as well as in the jaws, 

 in a separate sub-division, comprising this one species only. 

 In 1855, Nilsson suggested the name Ctenodon for the 

 species, in his "Skandinavisk banna." But this designation 

 having been adopted by Wagler, in 1830, for a reptile 

 (fain. Amriridw). by Ehrenberg, in 1838. for a species of 

 infusoria (Rotatoria), and by Swainson. in 1839. for a fish, 

 the name Leptoclinus — given by Gill in 1861, but not 

 characterized till 1864 — will have to be retained for this 

 sub-genus. 



Between Beinhardt's L. aculeatus, from Spitzbergen. 

 and Fries"s species L. maculatus, from Bohuslen, in Swe- 

 den, no difference whatever can be shown to exist. I have 

 carefully compared the individual in question from Spitz- 

 bergen with examples taken in the Christiania Fjord, and 

 tind them to be in every respect identical. The number 

 of fin-rays was generally the same. For the individual 

 taken on the North Atlantic Expedition, the tin-ray form- 

 ula is as follows: — D. 61; A. 37; P. '15 — 15; another 

 example, from the Isfjord, Spitzbergen. in the Tromso Mu- 

 seum, had D. 59; A. 35: hence the number would appear 

 to vary. Two individuals, taken in the Christiania Fjord, 

 had each 58 in the dorsal and 36 in the anal. 



The question of priority with regard to nomenclature 

 must be decided in favour of maculatus, the synonym sug- 

 gested by Fries. In 1837 was published the volume of D. 

 Vid. Selsk. containing Beinhardt's establishment of the 

 species by the name of Lumpenus aculeatus: and the same 

 year Fries furnished a full description of his Clinus macu- 

 latus (from Bohuslen) in Kgl. Vet. .Akad. Handl. Beinhardt
