ABSTRACT This study was undertaken to establish the identity of acantho- cephalan acanthors, acanthellae , and cystacanths parasitic in the sand crab Bmerita analoga (Stimpson). By studying the development of the cystacanths into the adult parasites in laboratory birds, the life history of Polymorphus altmani (Perry, 1942) Van Cleave, 1947, was es tablished experimentally.
