Habit stout; head of moderate size, its length being two-ninths of the total (without caudal); bones of the head very solid. Snout of moderate extent, broad, obtuse; teeth small; vomer with teeth anteriorly only. Maxillary similar to that of a Coregonus, short and broad, not extending to below the middle of the eye. Prae- operculum \dih a long lower limb. Adipose fin large and thick; caiidal deeply emarginate. Body with numerous brown spots. We refer two specimens from PaUas's Collection to this species: one (no. 86) is IS inches long, and evidently the typical specimen; the other (no. 84) is 21 inches long, and, although named " victtilis var. tahnen," is most certainly another individual of the same species.
