Abstract

The North Pacific prickleback Alectridium aurantiacum (Teleostei : Stichaeidae) is redescribed on the basis of 21 specimens collected from the central Kuril Islands. Special attention is given to the distribution of the cephalic sensory canals and pits. These specimens represent the first known records of this species outside the Commander and Aleutian Islands.
