southern boundary of the Commander Islands. In deep 

 waters (60—100 fathoms) the halibut is found in greater 

 quantity and of larger size, but fishing in such depths 

 requires special arrangements. As the markets are so 

 near, where fresh halibut is sold, as well as a simular 

 kind of fish called the Hippoglossoides, which have tasty 

 flesh, they ought to serve as a good object for trade, but 

 when salted the fish loses its quality and only satisfies 

 a very uncultivated taste. One may say the same about 

 the numerous specimens of flounders (Platessa). 



The specimens of the Chiridae class are characteristics 

 of the faun af the Pacific in their numerous species and 

 are of important economic value to the inhabitants of the 

 shore, as well as to the sea-animals. The Hexagrammus 

 monopterygius L. and G. is canned in large masses on the 

 Aleutian Islands and is known in the American markets 

 as Arctic mackerel, reminding of the real mackerel by 

 the taste of its salted flesh. The time, when this kind 

 of fish appears in shoals near the shore coincides with 

 the time of seal-killing and therefore the natives of the 

 Commander Islands conserve same for themselves in 

 a small quantity. The other kinds have only a local 

 signification. 



The specimens of Sebastes and Sebastodes (see photo- 

 graphs) which give excellent flesh may in the future attain 

 a small importance in trade, as they are delicious, when 

 canned. 



The different kinds of Cottidae, many species of which 

 and the majority belong only to the N. part of the Paci- 

 fic and have a considerable local economic value, serving 

 as food not only to man, but also to the sea-animals. On 

 the photographs are shown only members of the species 

 Hemilepidotus and one kind of Cottus. 



Of great importance to the cod-fish are the members 

 of the families Trichodontidae and Trachinidae, as well 

 as Cyclopterychtis, Arenaria and g. Mallotus; — the 

 coming of the cod-fish towards the shore depends on the
