Aualen har 1 1 Straaier, og begynder umiddelbart bag 

 Anus; den har Hojde og Udstrækning omtr. som 2den Dor- 

 sal, og slutter i en neppe kjendelig større Afstand fra Caiir 

 dalens Rod, end denne. 



Pectoraleme, dertælle 18 Straaier. undertiden 19 — 21, 

 ere bredt afrundede. som hos Slægten Cottus; i Spidsen 

 ere de nedre Straaier fri og noget fortvkkede. Tilbage- 

 slaaede naa de med Spidserne langt forbi Anus. eller 

 (hos de udvoxede Individer) ved eller noget forbi Begyn- 

 delsen af 2den Dorsal. 



Ventralerne ere forholdsvis lange, og naa med sine 

 fri Spidser næsten til Anus. De have 4 Straaier. 



Caudalen har 11 leddede Straaier, der i sin ydre 

 Fjerdedel ere kløvede. Paa hver Side af de leddede Straa- 

 ier tindes 3 — 4 uleddede Støttestraaler. der dog kunne 

 være næsten rudimentære. 



Farven. Denne viser hos de yngre Individer den 

 sædvanlige Fordeling af 3 graabrune Tverbaand tversover 

 Legemet, hvis Bundfarve er hvidagtig; det mellems.te af 

 disse Tverbaand. der udgaar fra Granden af 2den Dorsal. 

 er bredest, og har omtr. en Orbitaldiameters Bredde. Hos 

 ældre Individer ere Tverbaandene ikke saa skarpt tegnede, 

 idet de ofte indeslutte Felter af den lyse Bundfarve. lige- 

 som ogsaa Mellemrummene mellem dem kunne være saa 

 opfyldte af Smaapletter, at Tverbaandene blive ganske 

 utydelige. 



Finnerne, hvis Grundfarve er hvid (især hos de ældre). 

 ere forsynede med skarpttegnede. skraatlobende Tverbaand; 

 svagest tegnet er Analen, hvis Tverbaand oftest ere utyde- 

 lige Iovrigt er saavel Finnernes, som Legemets Farve- 

 tegning ikke ubetydeligt varierende hos de forskjellige In- 

 divider. 



Spæd Yngel, hvoraf jeg har et stort Antal fra Var- 

 angerfjorden med en Totall. af indtil 10""". have en ret 

 characteristisk Farvetegning, idet et sort Baand strækker 

 sig rundt Nakken og Struben som et Halsbaand; paa ,Si- 

 derne af Legemet gaar dette mørke Parti ud som en bred 

 Stribe. 



Forplantning, ete. Yngletiden for denne Art falder 

 sandsynligvis i Juli og August, da Here af de erholdte In- 

 divider havde Bugen stærkt udspilet af Rogn. Et af disse 

 (fra Stat. 275). der erholdtes den 2den Juli. og som havde 

 en Totall. af 69""". havde omtr. 32 Rogn i hvert Ovarium; 

 disse Rogn havde en forholdsvis betydelig Størrelse, idet 

 deres Diameter var omtr. 2""". Foruden disse 64 Bogn. 

 der alle vare jevnstore, og syntes at være fuldmodne. 

 fandtes et Antal yderst fine Rognkorn. der vare forblevne 

 uudviklede. 



Individernes Størrelse varierede hos de fleste mellem 

 66 og 83""". og de maa, da de viste sig forplantningsdygtige, 

 have været fuldvoxne eller nær derved. Dr. Liitken har 

 undersøgt et Exemplar fra Grønland (i Musæet i Kbhvn.). 

 der havde en Totallængde af 100'"" ■ 



The anal. furnished with 1 1 rays, commences im- 

 mediately behind the vent; height and extent about that 

 of second dorsal: it terminates, too. very nearly at the 

 same distance from the base of the caudal, as does that fin. 



The pectorals, furnished with 18 rays, sometimes 

 19 — 21. are broad and rounded, as in the genus Cottus; 

 extremities of lower rays free and somewhat thick. Direc- 

 ted backwards, the points extend some distance past the 

 vent; or (in full-grown specimens) a short distance beyond 

 the commencement of the second dorsal. 



The ventrals are comparatively long, the free points 

 extending almost to the vent: number of rays 4. 



The caudal is furnished with 11 articulated rays, 

 cleft in their outer fourth. On either side of the 

 articulated rays occur 3 — 4 auxiliary rays without ar- 

 ticulation, which, however, in some examples are almost 

 rudimentary. 



Colour. — Young individuals exhibit the normal di- 

 stribution: 3 greyish brown transverse bands across the 

 body, ground-colour whitish: the middle band, commencing 

 at the base of the second dorsal, is the broadest, having a 

 breadth about equal to the diameter of the orbit. In 

 maturer individuals the transverse bands are less distinctly 

 traced, being broken up with patches of the ground-colour ; 

 the intermediate space, too. is blurred with such a multi- 

 tude of spots and macules as to be frequently almost con- 

 fluent with the bands. 



The fins, the ground-colour of which is whitish, are 

 (more particularly in mature examples) marked with well- 

 defined, oblique transverse bands; marking of anal faint.' 

 the transverse bands being frequently indistinct. For the 

 rest, both the fins and the body generally display very 

 considerable variation in the distribution of colour. 



Fry in the earliest stage of growth, of which I am 

 in possession of a large number of specimens from the Varan- 

 ger Fjord (total length 10"""). exhibit a most characteristic 

 peculiarity of marking, a black band encircling the throat 

 and nuchal region like a necklace; on the sides, this dark 

 colour stretches posteriorly in the form of a broad stripe. 



Propagation &c. — The spawning season of this 

 species is probably in the months of July and August, the 

 abdomen in several of the specimens obtained having been 

 found distended with roe. One (Station 275). taken July 

 2nd. total length 69""". had about 32 ova in each ovary; 

 these ova were comparatively of large size, the diameter 

 being about 2""". Exclusive of these ova. 64 in number, 

 all of which were large and apparently mature, the ovaries 

 contained a number of minute ovarious germs, which had 

 remained undeveloped. 



The dimensions varied in most of the individuals 

 between (J6 and 83""". and these specimens, seeing they 

 were about to spawn, must have been full-grown, or very 

 nearly so. Dr. Liitken has examined an individual from 

 the coast of Greenland (preserved in the Zoological Mu- 

 seum. Copenhagen) with a total length of 100
