Abstract

An osteological study of representatives of the seven genera of creediids supports the view that the family is monophyletic. New diagnostic characters include the form of the pelvis, mesopterygoid, and ectopterygoid. Characters are given which distinguish members of Creediidae from other fishes. Three lineages of creediids are recognized on the basis of osteological and external characters, withSchizochirus insolens, the least derived and the most distinctive species, comprising the first lineage, the species ofCreedia the second, and those ofLinmichthys, Tewara,Crystallodytes, Chalixodytes, andApodocreedia the third.
