"October 25, 1985."

"The three-layered Schmelzmuster in lower incisors of eomyid rodents is described. It shows that even the specialized uniserial enamel in rodents can be further modified. The portio interna in eomyids is divided into two parts, and the Hunter-Schreger bands are longitudinal rather than transverse as is common in rodents. The inner part of the portio interna shows a type of uniserial enamel found in myomorphs in which all three axes are strengthened by fibers. The outer part resembles uniserial bands in sciurids, because crystallites of interprismatic matrix are parallel to the prisms. This complex Schmelzmuster and a longitudinal thickening of the enamel near the lateral side of the incisor are unique, derived characters of the Eomyidae"--P. [1].
