Abstract

The genus Pseudolittia Maubeuge is redescribed on the basis of new material, and Ammonites emilianus Reynes is assigned to it. The genus is characterized by straight ribs which die out on the later whorls and by decrease in the relative diameter of the umbilicus with increasing size of the shell. It is provisionally placed in the Subfamily Grammoceratinae.
