Article: The Jurassic echinoid Cidarites moniliferus Goldfuss and the status of Eucidaris

The type specimen of the Jurassic cidarid Cidarites moniliferus Goldfuss, recently designated as type species of the genus Eucidaris Pomel 1883, is redescribed. The species is considered to be a typical member of the genus Stereocidaris Pomel 1883. As these two genera were published simultaneously, it is recommended that Eucidaris should be abandoned in favour of Stereocidaris.
