Abstract
A sample of 84 dried skulls of Amia calva has been examined for variations in dermal bones and other parameters. One specimen was found with a single parietal and another with incomplete division of the parietals. Observations on parietal asymmetry, disposition of sutures, number and disposition of postorbitals, infraorbitals, number of dentary and premaxillary teeth, and tooth row/jaw length relations are quantified. Statistical analysis of five paired characters and dispersion analysis of 12 characters shows that the skull growth is isometric. Given a few measurements on a skull it is possible to predict several others.
