A New Record of the Heart Urchin<i>Rhynobrissus cuneus</i>(Spatangoida: Brissidae) from Buxton Beach, Dare County, North Carolina

Rhynobrissus cuneus, a small, irregular sea urchin, was originally described from 5 tests washed onto the beach at Fort Macon, NC, and it has been reported only once since, from 7 specimens collected from Playa Jicacal, Los Tuxtlas, Veracruz, Mexico. Here we record R. cuneus from Buxton Beach, Dare County, NC, ∼124 km (77 mi) directly northeast of the 1957 record. This is only the third report of R. cuneus and represents the northernmost record of the species. Specimens were found as empty tests washed ashore, most likely a result of recent beach-restoration activities.
