Abstract: The authors investigated the development of the tapeworm in dogs on the 15th, 117th and 290th day after oral infection by the Alaskan vole strain of multilocular hydatid cyst. The development of the sexual organ is very rapid ; it shows almost mature form while the strobila consists of 3 segments including a scolex and 2 proglottids on the 15th day after ingestion of hydatid cyst. The eggs of the tapeworm were first found in the feces of dogs on the 30th or 35th day after infection. There is a shade of difference between the two tapeworms on the 117th and 290th day after infection. Most of the worms, in these stages, consist of 5 segments including a scolex and 4 proglottids. Some of them, in the 3rd proglottid, have a bladder-like uterus just like that of the 4th proglottid or last one, but their eggs appear to be only glanules without characteristic chitinous shells or embryophores. Broadly speaking, this species matures earlier than E. granulosus. The difference between this species and E. granulosus will be established in a succeeding paper in detail.
