Irregularia; Cassiduloida; Pygaulidae
Remarks

Echinogalerus is distinguished from Pygopyrina, Adelopneustes and Conulus by having simple ambulacra, without pyrinoid plate development (Smith & Jeffery, 2000). Echinogalerus is also distinguished from Galerites in having an obviously oblique peristome and a transversely elongate periproct that is subtrigonal in outline. Galerites has a subcircular peristome and periproct (Smith & Jeffery, 2000).
