 ges paa 263 Favnes Dyb. Alle de under denne Expedition 

 erholdte Individer bleve fundne i den iskolde Area. hvor 

 Temperaturen paa Bunden var under CC. 



I Veutrikelen af det største Individ, en Han fra Jan 

 Mayen, fandtes blot et middelstort Exemplar af Themisto 

 1/helliiki. Mandt; hos den miudie Hun (fra Spitsbergen) 

 Dele af en Annelide (Polynop), samt af en Cinistacé. En 

 fuldt udviklet Hun 1'ra tijæsvær ved Nordcap. med en To- 

 tallængde af 1(>2""", det største Individ af denne Art. der 

 hidtil er fiindet ved Norges Kyster, indeholdt blot Levnin- 

 ger af Crustaceer, nemlig Dele af en Hippolyfe og af en 

 Pandalus. 



Legetiden foregaar maaske om Vinteren, idet Genera- 

 tionsorganerne hos Expeditionens Individer ikke for Øje- 

 blikket befandt sig i fuld Udvikling. Ovarierne hos Hun- 

 nen indeholdt saaledes endnu uudviklede Æg; Antallet af 

 disse var i livert Ovarium mellem 25lJ og 3(10, saaledes 

 ialt 5—600. 



Udbredelse. Tr. pingelii har Udbredelse fælles med 

 de fleste øvrige europæisk-arctiske Cottoider, og forekom- 

 mer sandsynligvis overalt paa passende Localiteter raeUem 

 Grønland. Novaja Zemlja, Island. Færøerne. og Norges 

 Kyster. Ved Grønland synes den ikke at være sjelden, og 

 flere Exemplarer ere herfra indlohne til Musæet i Kjoben- 

 havn. ligesom den i August 1876 erholdtes under den 

 engelske Nordpol-Expedition i Vest-Grønland under 79 " 29' 

 N. B. 



I Nord-America gaar den. ligesom et Flertal af rent 

 arctiske Fiske, forholdsvis langt længere mod Syd, end i Eu- 

 ropa, og er saaledes erholdt i Massachusetts Bay udenfor 

 New England under 42" N. B. Under de svenske Ex- 

 peditioner til Spitsbergen er den funden ved denne Øgruppe 

 allerede i 1861; ifølge Dr. Liitken er den ligeledes funden 

 ved Færøerne og Island, og Nordhavs-Expeditiouen har. 

 som ovenfor nævnt. erholdt den ved Jan Mayen. Endelig 

 forekommer den langs Norges Kyster ft'a Varangerfjorden 

 ned til Stat eller Christiansund (6I1/2"). men synes intet- 

 steds her at forekomme i noget betydeligt Antal. 



greater length than the adjacent normal rays. In this 

 peculiarily of structure an approximation is shown to the 

 motory and sensory organ, developed most in the genus 

 Trigla; the rays in that genus being entirely free, this 

 phrt of the fin can be moved about in all directions, and. 

 on the points of the rays being pressed into the gravel, 

 the fish appears to creep over the bottom. 



Tr. pingelii occurs in comparatively deep water only, 

 never ascending nearer the surface than 16 — 20 fathoms. 

 The greatest depth at which the species has hitherto been 

 observed is that from which the large-sized male specimen 

 was taken on the North Atlantic Expedition — 263 fath- 

 oms. All the examples obtained on the Expedition in- 

 habited the cold area, where the temperature at the bottom 

 was below 0" C. 



In the ventricle of the largest specimen, a male from 

 Jan Mayen, was found only a moderate-sized example of 

 Themisto lihelhtla. Mandt; in that of the smallest, a iemale 

 (from Spitzbergen), fragments of an Annelid ( Polynoe ) and 

 of a crustacean. The stomach of a full-grown female, from 

 Gjæsvær. near the North Cape, total length 102""". the 

 largest example of this species hitherto taken in Norway, 

 contained only fragments of crustaceans, viz. of a Hippolyte 

 and of a Pandalus. 



The spawning-season is perhaps in winter, since the 

 generative organs in the specimens taken on the Expedi- 

 tion were not then in a fully developed condition. The 

 ovaries, too. contained immature ova ; the number in each 

 ovary was from 250 to 30U. in both together from 500 

 to 600. 



Distribution. — Trigloj)s pingeJii has the range 

 common to most of the other Arctic CoUidce in Europe, 

 occurring probably in all favourable localities between 

 Greenland. Novaja Zemlja, Iceland, the Faroe Islands, and 

 the coast of Norway. On the coast of Greenland, it would 

 appear to he not a rare species, and examples from that 

 region have repeatedly been sent to the Zoological Mus- 

 eum in Copenhagen; it was taken, too, in 1876, on the 

 English North Pole Expedition, off the west coast of Green- 

 land, in lat. 79» 29' N. 



On the shores of western North America it occurs, 

 in company with a large majority of true Arctic forms, 

 comparatively farther south than in Europe, having been 

 observed in Massachusetts Bay, off the coast of New 

 England, in lat. 42" N. On the Swedish Expeditions to 

 Spitzbergen. in 1861, it was obtained off that grofUp of 

 islands; according to Dr. Liitken, it has also been met 

 with ott' the shores of the Faroe Islands and the coast of 

 Iceland; and on the North Atlantic Expedition, as previ- 

 ously stated, it was met with on the coast of Jan Mayen. 

 Finally, it occurs along the Norwegian coast, from the 

 Varanger Fjord as far south as Stat or Christiansund 

 (61" 30' N.), but nowhere, it seems, as a common species.
