ABSTRACT: New in vivo observations and collections of Ijimaiella, a monospecific genus of Euplectellidae (Porifera: Hexactinellida) from the Bering Sea provide the first look at the peculiar morphology of this sponge that was known before only from trawled fragments. New data on the spicule content and the generic diagnosis are given. The affiliation of the generic status and its position in the subfamily Corbitellinae is confirmed.

KEY WORDS: Corbitellinae, Bering Sea, genus-species description, Hexactinellida.
