As the result of field and laboratory investigations extending over a period of more than four years, we have amassed considerable information on the life cycle and ecology of a cestode of the genus Echinococcus (Rudolphi, 1801). Occurring on St. Lawrence Island, which lies in Bering Sea about 40 miles southeast of CapeChukotskyi, Northeast Siberia, this cestode not only has an interesting life cycle, but in the larval stage is an important parasite of man. Two outstanding characteristics serve to differentiate this cestode from the known species of Echinococcus: 1) the natural occurrence of the larval stage in microtine rodents; 2) an alveolar-form larva which is produced through exogenous budding. Although this cestode cannot always be differentiated from E. granulosus (Batsch, 1786) on the basis of morphological characters in the adult stage, it is nevertheless specifically distinct and is described herein as new.
