Cottus gratzianowi, a new cottid species, is described from material collected in the Ukhtomitsa River in the Onega River drainage, White Sea basin. It differs from its congeners in Europe east of the Meuse except C. koshewnikowi by having no transverse dark bands on the pelvic fin, a single chin ca...
