of fisliery-iuvestigatious in the Christiania Fjord a little Gadoid of quite a 

 peculiar appearance was often caught in the otter-seine, which had been 

 brought along from Denmark, a Gadoid which was not mentioned in the Scan- 

 dinaviau ichthyological Hterature; but according to later information from B. 

 Collett, it proved to be Gadiculus argenteus ouichenot, a small codfish, very nearly 

 related to the genus Gadus, and described by Gidchenot in »Explo ration Scien- 

 tifi(|ue de I'Algerie, Poissons. 1851«. It has afterwards been found in the Bay 

 of Biscaii by the »Travailleur«, and the » Talisnmui- found it at Morocco and 

 Sudan; finally the »Porciqnne« has takeu it west of Ireland on 183 fathoms' 

 depth. On the whole it seems to prefer depths of 2 — 300 fathoms in the Medi- 

 terranean and along the western shores of Europe; but now it appears to be 

 common also in the Christiania Fjord, and a small specimen of it has been 

 found (at station 9) in tlie Skager Rack, towards the Swedish coast, on 95 

 fathoms' depth, while another, and better, is preserved at Station 12. In the 

 southern European seas the fish occurs in great numbers; and it will surely 

 also be found to be common at oertain piaces in the Skager Rack, when once 

 this sea is properly investigated. As to Garej}rodus Reinhardt, from Green- 

 land, which has been described by Eeinhard and Krøyer, I shall mention only 

 that it was takeu, in 1879, by the Swedish gunboat >y Gunhild«, at about the 

 same place where it was now again found; this is the case also with Eaja 

 circularis. 



It has further been shown that Belastes, Gadus Pouiassou, Coryphcenoides 

 rvpestris, Argentina silus, and Chimcera monstrosa, fishes which otherwise are 

 rare with us, are found more or less commonly distributed in the deep part 

 of the Skager Rack, which is evidently to be looked upon as their proper 

 home. How many others of our rare fishes may be at home out here, we do 

 not know.
