Caledoniella montrouzieri is a reduced-spirally-coiled mesogastropod which lives on species of the stomatopod crustacean Gonodactylus throughout the tropical Indo-Pacific. The animal is adapted for its commensal existence by possessing a "sucker-like" foot. A fringe-like metapodium probably partially covers over the shell in life. A well-developed propodium below the proboscis serves in the formation and attachement of egg-masses and probably is involved in feeding activities. Placement of male gastropods on terminal thoracic or anterior abdominal and of females on posterior abdominal segments of Gonodactylus indicates a possible preferences of these loci as habitats, although the female, at least, moves about on the abdomen of the host during egg-laying and probably feeding activities. The family Caledoniellidae is proposed for Caledoniella montrouzieri and the group is assigned to the superfamily Hipponicacea with which it shows strongest relationship. 7 pp., 4 figs, 1 pl., 4.…
