 hele Legemet er transparent (paa Spiritus hvidagtigt)- med 

 en Række sorte Pigmentpuncter langs Dorsalei-ne. Enkelte 

 Tænder ere fremkomne paa Underkjanen : Xakkekammen 

 er temmelig skarp og tydelig, og ender bagtil i en tre- 

 dobbelt Pig. 



Forudeu de nævnte Yngel-Iudivider erholdtes under 

 Expeditionen tiere Unger, der optoges med •Bundskraben 

 eller Trawlnettet fra 120 iudtil 150 Favnes Dyb paa til- 

 dels iskoldt Yand. 



Hos den luindste af disse Unger, hvis Totall. er 02'""' 

 (Stat. 275). er Legemet allerede bleven livligt farvet med 

 3 — 4 brunsorte Tverpletter over Ryggen; tydeligst og bre- 

 dest er den næstsidste. der stiger ned paa begge Sider af 

 Dorsalens bløde Del; den sidste staar over Haleroden. 

 Dette er den samme Fordeling af Pletter, der er gjennem- 

 gaaende bos de yngre Individer af de Heste cottoide Fiske.

Udbredelse. »S'. marhiuti er en nordisk Art. der 

 har sit Tilhold ved Grønland. Island. Spitsbergen. Novaja 

 Zemlja. samt ved Nord-Europas Kyster ned til Stavanger 

 og Lindesnæs; paa den americanske Side gaar den sand- 

 synligvis ned lige til New England, omtrent under 40" N. 

 B. Som en ægte Dybvandsart synes den normalt ikke at 

 trænge ind i Nordsøen. og er derfor blot sporadisk trutfen 

 ved Danmarks og Englands Kyster, og den gaar heller 

 ikke ind i Kattegat og . Østersøen. 



Yed Norges Kyster østenfor Lindesnæs. og i de syd- 

 ligste Fjorde. samt ved Bohuslen erstattes den af den 

 meget uærstaaende Form S. viviparns. Kr., der tillige. 

 ifølge Dr. Liitken. optræder ved Færtierne. men mangler 

 ved Danmark. I Norge gaar denne op idetmindste til 

 Trondhj emsf j orden . 



• I Nord-America synes Forholdet mellem de 2 Arter 

 endnu ikke at .være bragt fuldkommen paa det rene. 

 Medens Gill (Proc. Ac. Nat. Sei. Philad. 1863. p. 

 333) opfører den ved New Englands Kyster forekom- 

 mende Form som *S'. riviparus, ganske med Udelukkelse

rays developed, and the number of the latter normal. The 

 scales were as yet wanting; the body was everywhere trans- 

 parent (preserved in spirits whitish), dotted along the dorsals 

 with a series pflilack.pigmentary points; a few teeth devek)i)ed 

 in the lower jaw ; the. comb on the najie was sharply defined, 

 terminating behind in a trifurcate spike. 



Exclusive of the individuals describ-ed above, in the 

 fiy stage of growth, several young specimens were obtained 

 on the Expedition; they were taken when dredging the 

 bottom or trawling, at a depth varying from 120 to 150 

 fathoms, the water having in places the temperature of ice. 



In the smallest of these young exam])les (station 275).

 with 3 — 4 brownish-black transverse spots in the dorsal 

 region ; the broadest and most distinct is the last but one. 

 which descends down along the soft portion of the dorsal; the 

 terminal spot is immediately above the origin of the tail. 

 This is the conunon- distribution of spots in young exam- 

 ples of most Cottoid fishes. A cluster of pigmentary points 

 gives the appearance of an indistinct spot on the npper portion 

 of the operculum (a characteristic peculiar to full-grown indi- 

 viduals of the coastal form Seh. r/ripariis, Kr.); but this 

 spot gradually disappears with the gVowth of the fish, leav- 

 ing hardly a vestige in adult examples. The scales were 

 fully developed.

Distribution. — S. marinns is a northern species; 

 it occurs oft' the coastS' of Greenland. Iceland, Spitzbergen. ' 

 Nova Zemlja, and the shores of northern Europe, at least 

 as far south as Stavanger and the Naze; in the westei'p 

 hemisphere its range probably extends along the coast of 

 North America, as far south as the New England States, 

 in lat. about 40" N. As a true deep-sea sjiecies, it can 

 hardly pass the North Sea;- hence it occiu's. sporadic- 

 ally, oft' the coasts of Denmark and Great Britain, and does 

 not frequent the waters of the Cattegat or the Baltic. 



On the coast of Norway, east of the Naze, and in the 

 most southern of the fjords, (is well as oft' Bohuslen, this 

 species is replaced by the closely allied S. riripariis, Kr.. 

 which, according to Dr. Liitkeu, also occur.s oft' the Faroe 

 Islands ; but it is not met with on the coast of Den- 

 mark.' In- Norway it certainly extends as -far north as the 

 Trondhjem Fjord. 



The distribution of the two species in North America 

 does not appear to have been fully ascertained. Gill ( Proc. 

 Ac. Nat. Sci. Philad. 1863. p. 333) describes the form 

 occurring on the coast of New England as ^S". ririparus. 

 and does not even mention 8. marhms ; on the other hand.
