Some fossil Clypeastrids (Echinoidea) from Brimstone Hill (St. Kitts) and Sugar Loaf (St. Eustatius), Lesser Antilles

In March 1958 Dr. J. H. WESTERMANN and Mr. H. KIEL collected some fossil Echinids on the islands of St. Kitts and St. Eustatius. The fossils of St. Kitts were found in a yellow limestone (sample nr. 42), situated on the west flank of Brimstone Hill, belonging to a series of peculiar-looking upturned sedimentary beds, occurring around a volcanic plug (MARTIN-KAYE, 1959). According to C. T. TRECHMANN (1932) the fauna of these beds is put down as Pliocene, possibly late Pliocene.
