Det første Exemplar, fra Expeditionen i L876, dptoges 

 mrd det fine Overfladenet fra Vandskorpen paa Fiskebanken 

 Storeggen udenfor Christiansund (Norge), og \;ir øjensynlig 

 udkastet i halvfordøjet Stand af en Fiskemave. Skjælbe- 

 klædningen manglede saagodtsom overalt, Ugesom mindre 

 Dele af Legemets Sider vare fortærede; derimod rare Fin- 

 nerne forholdsvis vel vedligeholdte, ligesom de sølvgbndsende 

 (phosphorescerende?) Petter langs Bugen næsten overalt 

 vare i Behold. 



De 3 Exemplarer fra Expeditionen i 1S7S v&re alle 

 DOget over halvt udvoxede, og optoges fra Havet langt 

 vestenfor Hammerfest med Trawlnettet, der her naiede Bund 

 paa 1110 Eavnes Dyb. Ogsaa ber mangler Skjælbeklæd- 

 ningen saagodtsom fuldstændig, og flere Finner ere afbrudte ; 

 især er Caudalen defect, saa at Individernes Totallængde 

 ikke nøjagtigt.kan opgives. 



De langs Ventrallinien løbende sørVglindsende Pletter 

 ere (forsaavidt de kunne sees. eller ere i Behold) fordelte 

 paa følgende Maade: 



Mellem Struben og Ventralerne 5 Par; det øverste 

 er bedækket af Grjællelaagene, naar disse ere helt tilsluttede. 



Mellem Ventralerne og Ana len 4 Par: dette Tal er 

 constant bos alle de af mig hidtil undersøgte Exemplarer. 

 (Kroyer angiver 3 i ovenfor anførte Beskrivelse). 



Langs Analen tindes 7 Par; hos et i Universitets- 

 Musæet opbevaret nogenlunde fuldstændigt Exemplar fra 

 Hasvig ved Hammerfest er der mellem den 5te og 6te Pl et ét 

 noget større Mellemrum, end mellem de øvrige; hos de 2 

 af Exemplarerne fra Nordhavs-Expeditionen, hvor disse 

 Pletter ere blevne bevarede, er der derimod et lignende 

 Mellemrum mellem den 6te og 7de Plet. 



Mellem Analen og Caudalen tindes 6 Par. der alle 

 staa tættere sammen, end i de foregaaende Rækker. 



Ved Roden af Caudalen nedenfor Midtlinien tindes 1 

 Par. 



De forskjellige enkeltstaaende Pletter eller kortere 

 Rækker, der tindes hist og her paa Legemets Sider, kunne 

 ikke eiter de forhaandeimerende Exemplarer beskrives. 



De erholdte Exemplarer havde følgende Maal og 

 Straaleantal : 



The lirsi individual, obtained on the cruise in L876. 

 was taken ln the fine-meshed surface-net, on «the Storeggen 

 fishing-bank, off Christiansund (Norway), and bad evidently 

 been ejected in a half-digested state from a fish's stomach, 

 The scales were almost every where wanting; moreover-, small 

 portions ol' the sides of the bodj had disappeared; the 



lins. on the other hand, were comparatively uninjured, as 

 also the argenteous (phosphorescent r) spots extending along 

 the abdomen. 



The -'i specimens taken on the last cruise of the Ex- 

 pedition, in 1S7S. were all a little re than balf-grown; 



they were captured at sea. far west of Hammerfest, in the 

 trawl-net. which had been sunk to the depth of 11 K' 

 fathoms, (hi these specimens, too. hardly a scale remains. 

 and several of the fins are broken, more especially the 

 caudal: hence the total length cannot be accurately stated. 



The silvery spots along the ventral line were disposed 

 (sq far as the condition of the individuals admitted of ob- 

 serving them), in the following order. 



Between the throat and the ventrals 5 pairs, the upper- 

 most covered by the gill-plates, when the latter are closed. 



Between the ventrals and the anal 4 pairs; this num- 

 ber' is constant in all the examples I have hitherto exam-' 

 ined (Kroyer gives 3 in "Naturh. Tidsskr."). 



Along the anal 7 pairs; in a specimen, comparatively 

 perfect, preserved in the University Museum, from Hasvig 

 near Hammerfest, the space between the 5th and 6tb spots 

 is somewhat wider than that between the others; 2 of the 

 individuals obtained on the North Atlantic Expedition in 

 which these spots are visible, have a similar space between 

 the 6th and 7th spots. 



Between the anal and the caudal G pairs, more closely 

 arranged than in any of the foregoing series. 



At the origin of the caudal, below the mesial line. 1 

 pair. 



The various isolated spots or shorter series occurring 

 here and there on the sides of the body cannot be determ- 

 ined from the specimens taken on the Expedition. 



The measurements and tin-ray formula' in the specimens 

 obtained, were as follows: —

The number of fin-rays in the anal could he determ- 

 ined with comparative accuracy in hut two of the individuals: 

 One of them had the terminal anal ray double.; in the 

 other specimen this character is not distinct. 



Food. — The stomach of one of the individuals taken 

 at Station 295 contained fragments of a Themisto libellvla, 

 Mandt, together with several examples of Conccecia boredlis,
