Aualen har 11 Straaler. og begynder umiddelbai't bag 

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

 sal, og slutter i en neppe kjendelig større Afstand fra Cau- 

 dalens Rod. end denne. 



Pectoralerne. der tælle 18 Sti-aaler. undertiden 19 — 21, 

 ere bredt ati'undede. som bos Slægten Cottus : i Spidsen 

 ere de nedre Straaler fri og noget fortj-kkede. Tilbage- 

 slaaede naa de med Spidserne langt forbi Anus, eller 

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

 delsen af 2deu Dorsal. 



Yentralerne ere forholdsvis lange, og naa med sine 

 fri Sjjidser n;esten til Anus. De liave 4 Straaler. 



Caudalen har 11 leddede Straaler, der i sin ydre 

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

 ler lindes 3 — 4 uleddede Støttestraaler. der dog kimne 

 være mesten rudimentære. 



Far ren. J)enne viser hos de yngre Individer den 

 sædvanlige Fordeling af 3 graabruue Tverbaand tversover 

 Legemet, hvis Bundfarve er hvidagtig; det mellemste af 

 disse Tverbaand. der udgaar fr-a Grundeu af 2den Dorsal, 

 er bredest, og har onitr. 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 lilive ganske 

 utydelige. 



Finnerne, hvis Grundfarve er bvid (især hos de ældre), 

 ere forsynede med skarpttegnede. skraatløbende Tverbaand; 

 svagest tegnet er Analeu. hvis Tverbaand oftest ere utyde- 

 lige, løvrigt er saavel Finnernes, som Legemets Farve- 

 tegning ikke ubetydeligt varierende hos de forskjellige In- 

 divider. 



Spæd Yngel, hvoraf jeg har et stort Antal ft-a Var- 

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

 characteristisk Farvetegning. idet et sort Baand strækker 

 sig rundt Naklcen og Struben som et Halsbaaud; paa Si- 

 derne af Legemet gaar dette mørke Parti ud som en bred 

 Stribe. 



rorplantning. etc. Yngletiden for denne Art falder 

 sandsynligvis i Juli og August, da flere af de erlioldte In- 

 divider liavde 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 Rogii i hvert Ovarium; 

 disse Rogn havde en forholdsvis betydelig Størrelse, idet 

 deres Diameter var omtr. 2""". Foruden disse 64 Rogn, 

 der alle vare jevnstore, og syntes at være fuldmodne, 

 fandtes et Antal yderst fine Rognkorn. der vare ibrblevne 

 uudviklede. 



ludividernes Størrelse varierede hos de fleste mellem 

 66 og 83 """, og de maa, da de viste sig forplautningsdygtige, 

 have været fuldvoxne eUer nær derved. Dr, Liitkeu har 

 undersøgt et Exemplar ft-a Grønland (i Musæet i Kbhra,), 

 der havde en Totallænsde af lOO""'- 



The anal, furnished with 11 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 al)out equal to the diameter of the orbit. In 

 maturer individuals the transverse bands are less distinctly 

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

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

 tude of spots and macules as to l)e 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 bauds; 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 sjiecimens ft-om the Varan- 

 ger Fjord (total length 10'"'"). exhil)it 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 &e. — The spawning • season of this 

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

 abdomen in several of the specimens obtained having been 

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

 2nd. total length G9 '"'", 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 66 and 83'"'". and these specimens, seeing they 

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

 nearly so. Dr. Liitkeu has examined an individual from 

 the coast of Greenland (preserved in the Zoological Mu- 

 seum. Copenhagen) with a total length of lOO'"'"-
