Abstract
The first illustrated description of two larvae of the rare deep-water genus Lyconus from the North Pacific Ocean has been given. The studied specimens differ from the previously described larvae of L. pinnatus in complete and uniform pigmentation of the body. The new materials complement the existing ideas about the geographical distribution of representatives of the family Lyconidae – this is their first finding in the waters of the Pacific Ocean.
