Remarks.—The material (NMV P309618) examined agrees fully with the description of the species given by Shen et al. (1999). According to these authors, Peltichia is generally confined to the Changhsingian. However, the presence of P. zigzag in the upper Lungtan Formation places its origin in the late Wuchiapingian. Within the genus, P. zigzag is separated from P. transversa ( Huang, 1933) by its larger size, more elongate outline and strongly parasulcate anterior commissure.
