Echinolampas woodringi n. sp., Pericosmus israelskyi n. sp., Schizaster costaricensis n. sp., Schizobrissus kewi n. sp., Plagiobrissus costaricensis n. sp., and P. malavassii n. sp, are described. Brissopsis, n. sp., and Clypeaster sp. indet. are recorded and figured. It is concluded that the echinoids probably lived in water between 100 and 300 m. deep. Most of these echinoids have their closest relatives in the Meson and Tuxpan formations of Mexico and the Ojo de Agua formation of Venezuela.
