These two speciescan be recognizedinitially by theirdistinctive pigmentpatterns. Fresh material shows Anthomuda stenotelson Schultz to be a junior synonym of Antheluraaffinis Richardson.Also included in the report are the descriptionsof two new species collected from a cave, Munnogoniumsomersensis and Stenobermudailiffei. The latter, which exhibits protogynoushermaphroditism, is shown to be a member of the Gnathostene- troididae. While several reportson the isopod fauna Of the marine forms, the genus Carpias of Bermudahave been published (Richard- appears to be ecologically the most wide- son, 1902; Schultz, 1986; Kensley and spread,occurring in 86 of the 114 collection Schotte, 1989), the collection of about 1,500 stations (see Table 1).
