Another unnamed species o^ Anglonautilus occurs in various localities in south- em California. This species differs from A. catarinae in that the former has less curvature to the suture (Fig. 4), and umbilical plug, and weak development of the ventral folds diagnostic of the genus. Thus Anglonautilus sp. occurs in sediments of Turonian to Campanian age. Four previously named species of Anglonautilus are known from England, Europe, or Japan. Anglonautilus catarinae is most similar to A. japonicus Mat- sumoto and Takahashi (1982) from the lower Cenomanian of Japan in overall shape but differs in the latter's more numerous and relatively laterally persistent ventral fold-like undulations, the clioscaphitoid shape of the adult shell, shallow.
