The teeth of some of the Sparoids have a strongresemblance to the fossil; but the serrated preoperculum forbids itsapproach to that family. The dentition of the Sciaenoids varies muchin character, almost to the two extremes of dents en pave and dentsen velours, so that, on the whole, the dentition of the fossil is such asmight exist in a Sciaenoid genus. But one of the main characteristicsof the Scisenoids is the prevalence of numerous mucous ducts tra-versing the bones of the face and jaws, and in this respect the fossilis irreconcileable with this family.
