Centridennichthys uncinatus is one of the small, 

 tliough not of the smallest, Cottoids. On the coast of 

 (Ireeiiland, according to Lutken, it attains a length of 

 100 mm. The size is said by Jordan and Gilbert to 

 l)e the same on the east coast of North America, where 

 it occurs as far south as Cape Cod. The largest of the 

 specimens taken by the Vega Expedition are only 

 slightly smaller, being about 92 mm. in length. These 

 specimens were found in different parts of the Arctic 



Ocenn oft' Siberia., from Taimvr Sound to the winter- 

 quarters of the expedition near Behring Strait: they 

 Avere taken at spots where the bottom -was sand}' or 

 stony, and most often among seaweeds, at a depth of 

 from 5 to 13 fathoms. The species was first described 

 from specimens found in Greenland. On the coast of 

 Norway it was first found by G. 0. Sars in 1865, nenr 

 Lofoden, and by Essiakk in 1866, oft' Hammerfe.st. It 

 was taken oft' Nova Zembla by Heuglin in 1871. It 

 has subsequently been caught at various spots along 

 the whole coast of Norway, as far south as the Whale 

 Islands, on the Swedish frontier; but in its southern 

 haunts, like other arctic forms, it lives at greater depths. 

 Even in its true habitat, the Ai'ctic C)cean, it was 

 t;iken by the Norwegian Arctic Expedition at a depth 

 of 223 fathoms, south-east of Bear Island. Singularly 

 enough it has not yet been met with on the coasts of 

 Spitzbergen or of Iceland. 



Its food, like that of the preceding species, is 

 composed of worms and crustaceans.
