What is "cottocomephoridae"

Cottocomephoridae, or the bighead sculpins or Baikal sculpins, are a family of scorpaeniform fishes mostly endemic to Russia (one species ranges into Mongolia) where they are mostly found in Lake Baikal and surrounding lakes and rivers.

The Catalog of Fishes does not recognize Cottocomephoridae as a separate family, but includes its members in the Cottidae.
