Bemærkninger til Synonymien. Slægten Tr/r/lops 

 opstilledes af Reinh. sen. allerede i Overs, for 1829 — 30, 

 Kgl. D. Vid. Selsk. Nat. Math. Afli. 5 B. p. LII (Kbhvn. 

 1832) efter et Exemplar i'ra Grønland; men først i 1838 

 blev den i samme Tidsskrifts 7 de Bind meddelt sit Arts- 

 navn. Den viser i Uere Henseender en Tilnærmelse til 

 Slægten TrigJa, saaledes i Tandbygningen, Hovedets Form, 

 de fintandede Ski'aalinier nedad Legemets Sider, og de 

 nedtil stærkt fri Pectoralstraaler. 



T. i)'ni(i<-Hi er den eneste liidtil sikkert bekjendte Art 

 af denne Slægt. Ligesom det var Tilfældet med Centrid. 

 nnniiatuti, blev den af Reinh. kun ganske kort characteri- 

 seret; derimod gav Kroyer i 1844 (Xaturli. Tidsskr. 2den 

 R. Iste B.) efter det i Kblivns. Musæum foreliggende Ma- 

 teriale en udførligere Diagnose af saavel Slægt, som Art, 

 og efter disse ere Giinthe)'s Diagnoser i Cat. Fishes Brit. 

 Mus. vol. 2 (1860) atfattede, da endnu intet Indiv. forelaa 

 i British Museum. I 1864 erholdt Malmgren et Individ 

 ved Spitsbergen; senere er den gjentagne Gange bleven 

 korteUg omtalt fra Norge, ligesom Dr. Liitken har nærmere 

 omhandlet de i Musæet i Kbhvn. opbevarede Exemplarer 

 fra Grønland i Vid. Medd. Naturh. Foren. Kbhvn. for 

 Aaret 1876. 



Af Kroyer er den bleven afljildet i Gaimards Plau- 

 cheværk (Voy. Scand. Lap. etc. 1838-^40, Poiss. pl. 1), 

 men denne Atbilduing er i flere Henseender iifuldkommen. 

 En udførligere Beskrivelse af T. pingeUi er hidtil intet- 

 steds bleven leveret. 



Beskrivelse. Legemshygning. Hele Legemet er oven- 

 til, ligesom Hovedet, tæt beklædt med fine Granulationer, 

 og nedenfor Sidelinien med tandede Hudfolder ; blot Gjælle- 

 membranen er nøgen. Pectoralei'ne og Øjnene ere forholdsvis 

 særdeles store. Hannerne ere kjendelige ved sin overor- 

 dentlig store Analpapille, der ved Gruudeu omtrent har en 

 Lindsediameters Tykkelse, og er rettet uoget fremad; dens 

 Længde udgjør omtrent en Orbitaldiameters Bredde. Halen 

 er temmelig lang og uddragen, og Haleroden er forliolds- 

 vis lav.

Remarks oti the Synonymy. — The genus Triglops 

 was fi^st established by Reinhardt sen., in Kgl. D. Vid. 

 Selsk. Nat. Math. Atli. Overs, for 1829—30, 5 B. p. LII 

 (Kbhvn. 1832), from a specimen taken on the coast of Green- 

 land; it did not however receive its specific name before 

 1838. in the 7th volumne of the said Journal. This 

 genus approximates in many of its characters the genus 

 Trigla; for instance, in the dentition, the foriji of the 

 head, the obli(]ue serrate lines traversing the sides of 

 the body, and in the pectoral rays being to a great 

 extent free. 



T. pingelii is the only species of this genus with cer- 

 tainty known to have been observed. As had been the 

 case with Cenfrid. unchiafns, its generic characters were 

 but briefly set fortii by Reinhardt sen. ; on the other hand, 

 Kroyer, in 1844. from materials in the Zoological Museum 

 at Copenhagen, gave a detailed diagnosis both of the 

 genus and the species, which is the source whence (Tiinther 

 has furnished liis diagnosis in Cat. Fishes Brit. Mus. 

 vol. '2 (1860), as the British Museum had no example of 

 the species. In 1864 Malmgren obtained a specimen from 

 the coast of Spitzbergen ; since then it has been repeatedly 

 mentioned as occurring ofl' the Norwegian coast; aiul in 1876 

 Dr. Liitken treated of the specimens preserved in the Zoo- 

 logical Museum of Copenhagen in Vid. Medd. Naturh. 

 Foren. Kbhvn. for that year. 



The species has been figured by Kroyer in one 

 of the plates to Gaimard's work (Voy. Scand. Lap. etc. 

 1838 — 40; Poiss. pi, 1); but this representation is in 

 several respects laulty. A detailed descrij^tion of T. pin- 

 gelii has not as yet been furnished. 



General description. Structure of the Body. — Body, 

 above, and head, closely studded with minute granula- 

 tions; dentate membranous folds below the lateral line, 

 branchial membrane only smooth. Pectorals and eyes com- 

 paratively large, Male individuals easily distinguished by 

 the remarkable size of the anal papilla, which projects 

 slightly forward; its thickness at base about equal to the 

 transverse diameter of the lens, and its length, to the 

 diameter of the orbit. Tail rather long and elongate, 

 slender at base.
