(ISOMYA) GERARDI, A NEW SPECIES OF SIPUNCULA IS DESCRIBED FROM LITTORAL WATERS OF THE BAHAMAS, BELIZE, AND THE YUCATAN COAST OF MEXICO WHERE IT INHABITS RUBBLE ASSOCIATED WITH CORAL REEFS. A NEW INTERSTITIAL SPECIES P.(P.) PSAMMOPHILUS, IS DESCRIBED FROM DEPTHS OF 15-19M OFF THE COAST OF E. CENTRAL FLORIDA. IT IS THE FIRST SIP. DOCUMENTED AS AN ADULT RATHER THAN A JUVINILE TO BE REPORTED AS A MEMBER OF THE MEIOFAUNAL COMMUNITY. OBSERVATIONS ON DEVELOPMENT RESULTING FROM LABORATORY SPAWNINGS REVEAL A TYPICAL LECITHOTROPHIC TROCHOPHORE AND A SHORT LIVED LECITHOTROPHIC PELAGOSPHERA LARVA THAT TRANSFORMS INTO A CRAWLING JUVINLE AT 4 DAYS OF AGE. STATION DATA FOR THESE COLLECTIONS ARE PRESENTED IN AN APP..},
