It does not occur at Bermuda nor is it known from the Bahamas, but it is recorded from both Cuba (northwestern coast only) and Hayti (an old record that needs verification). It does not occur at Jamaica, nor is it known from Porto Rico or the Lesser Antilles, but it does occur in Trinidad and Tobago. It occurs on the coast of Yucatan and has been reported from Brazil; the latter record, however, is probably due to confusion with the Brazilian species, Arbacia lixula (L.). This distribution is quite incomprehensible, but comparison of specimens from Tobago, the Tortugas, and Massachusetts shows no reason to doubt that all are punctulata. The range of Echinometra viridis is quite restricted, extending only from the Tortugas to St. Thomas, but Clypeaster rosaceus ranges northward along the coast to South Carolina, southward at least to Guadeloupe, and is common in the Bahamas. The range of Encope michelini is like that of Echinaxter tenuispinus, from the Tortugas northward along the west coast of Florida and thence westward along the Gulf Coast to Mexico. The remarkable spatangoid Moira has a peculiar distribution, being common at Beaufort, North Carolina, but known also from Florida, Texas, Jamaica, St. Thomas, and Gaudeloupe.
