In Phycis, how- ever, the lateral ethmoid wing is a broad, downwardly curved lamina showing no trace of modification. In the Ranicipitidae, the lamina is thin and directed outwards in a near-horizontal plane (Fig. 30E), while that of Muraenolepididae is narrow, thick and downwardly directed (Howes, 1987; fig. 4b)

In both latter families the lateral ethmoid appears much modified and does not exhibit any evidence of a gadid morphotype. In other gadoid families the lateral ethmoid wing has, what is considered to be the plesiomorphic form namely, a broad, downwardly directed lamina (typically in Bathygadidae, Howes & Crimmen, 1990; fig. 2B). As far as Macruronus is concerned, the lateral ethmoid bears no resemblance to the gadid-type, nor to the plesio morphic form, rather it is intermediate. Unlike Merluccius, however, which bears traces of a cone-shaped, gadid-type.
