 hele Legemet er transparent (paa Spiritus hvidagtigt) med 

 en Etække sorte Pigmentpuncter langs Dorsalerne. Enkelte 

 Tænder eve fremkomne paa Underkjæven; Nakkekammen 

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

 dobbelt Pig. 



Foruden de nævnte Yngel-Individer erholdtes under 

 Expeditionen tiere Unger, der optoges med Bundskraben 

 eller Trawlnettet fra 120 indtil 150 Favnes Dyb paa til- 

 dels iskcddt Vand. 



Hos den mindste af disse Inger, hvis Totall. er 62""" 

 (Stat. 275), er Legemet allerede bleven livligt tarvet 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 hos de yngre Individer af de Heste cottoide Fiske.

 Grjællelaagets ovre Del (en Character, der tilkommer de 

 fuldt udvoxede Individer af deu deciderede Kystform Séb.

 bos de større Unger næsten ganske. Skjælbeklædningen

Udbredelse. 8. mariwus er en nordisk Art. der 

 bar 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 truffen 

 ved Danmarks og Englands Kyster, og den gaar heller 

 ikke ind i Kattegat og Østersøen. 



Ved Norges Kyster ostenfor Lindesnæs. og i de syd- 

 ligste Fjorde, samt ved Bohuslen erstattes den af den 

 meget nærstaaende Form S. viviparus, Kr., der tillige. 

 ifølge Dr. Liitken. optræder ved Færøerne, men mangler 

 ved Danmark. I Norge gaar denne op idetmindste til 

 Trondhjemsfjorden. 



I Nord-America synes Forholdet mellem de 2 Arter 

 endnu ikke at være bragt fuldkommen pan det rene. 

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

 333) opfører den ved New Englands Kyster forekom- 

 mende Form som S. viviparus, ganske med Udelukkelse

rays developed, and the number of the Latter normal The 

 scales were as yet wanting; the body was every where trans- 

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

 with a series ol' black pigmentary points: a few teeth developed 

 in the lower jaw; the comb on the nape was sharply defined, 

 terminating behind in a fcrifurcate spike. 



Exclusive of the individuals described above, in the 



fry stage of growth, several young specimens were obtained 

 on the Expedition; they were taken when dredging the 

 bottom or trawling, at a deptli varying trom L20 to 150 

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

 In the smallest of these young examples (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 common distribution of spots in young exam- 

 ples of most Cottoid tishes. A cluster of pigmentary points 

 gives the appearance of an indistinct spot on the upper portion 

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

 viduals of the coastal form 5186. wviparus, Kr.); but this 

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

 ing hardly a vestige in adult examples. The scales were 

 fully developed.

Distribution. — (S', maritim is a northern species: 

 it occurs off 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 western 

 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 species, it can 

 hardly pass the North Sea; hence it occurs, sporadic- 

 ally, off the coasts of Denmark and Great Britain, and does 

 not frequent the waters of the Oattegat or the Baltic. 



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

 most southern of the fjords, as well as off Bohuslen, this 

 species is replaced by the closely allied 8. rir/pant.--. Kr., 

 which, according to Dr. Liitken. also occurs off 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 

 Trohdhjem Fjord. 



The distribution of the two species in North America 

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

 Ac. Nat. Sci. Philad. 1863. p. 333 1 describes the form 

 occurring on the coast of New England as v 

 and does not even mention S. marimts ; on the other hand.
