It may safely SKULL 347 be assumed that the condition in which tlie parietals meet inthe middle line and are not separated by the supraoccipital isprimitive ; it is found in the lower Teleostomes, whore, indeed,the supraoccipital has not yet appeared (p. 32G). But, although itis the rule in the lower sub-orders that the parietals meet, yet evenin the Clupeiformes there are genera in which the supraoccipitaltouches the frontals underneath the parietals {Elops, Alhida, Chanos),and among the Acanthopterygii the parietals may sometimes meet /uu. riv-.
