The larvae of Loxosoma pectinaricola and Loxosomella elegans are described and figured. They lack the frontal organ and the foot characteristic of all hitherto described entoproct larvae. The larva of Loxosomella elegans resembles a generalized trochophora. Preliminary observations indicate that the larva of Loxosoma pectinaricola has a long planktotrophic life.
