Abstract
Cenomanian rocks of Egypt are rich in moderately to well-preserved echinoids. From the large Cretaceous echinoid collection at the Cairo Geological Museum, a total of 27 regular species, in 12 genera, eight families, six orders and two subclasses, are revised and systematically described from these strata as exposed at several localities in Egypt. One new family (Pedinopsidae), one new subfamily (Lorioliinae), one new genus (Alternocidaris) and two new species of Goniopygus, G. subaequalis (Gebel Ekma) and G. macrotuberculatus (Gebel El Minsherah), are erected. Additionally, two species of Diplopodia, D. micropyga Fourtau, 1921 and D. halperti Fourtau, 1921, are transferred to the genus Pedinopsis.
