Rattus norvegicus, then redescribed by SKRJABIN and MATEVOSIAN (1948) from the same host. SPASSKY (1954a) accepted BAER * s (1932) views, who considered the species H. procera Janicki, 1904 and H. arvicolina Cholodkowski

, 1912, described from Arvicola terrestris, as junior synonyms of H. horrida

. Moreover, he also included H. sciurina Cholodkowski

, 1912, sensu SKRJABIN et MATEVOSIAN, 1948, as a synonym of H. horrida. and in the same year (1954b) in another paper he also synonymized Oligorchis nonarmatus Neiland, 1952, with H. horrida (cf. TENORA, 1967). Pig. 1 : Hymenolepis horrida (Linstow, 1901) A= Scolex; B= Egg with oncosphere; C= Cirrus with spines; D= Hermaphrodite segment (A-D orig.) As far as the hosts are concerned, SPASSKY (1954a) states that H. horrida,,is-, first of all, a parasite in rodents of the subfamily Microtinae, despite being recorded more often from members of the family Muridae (e.g., DUBININ 1953, SHALDYBYN 1954,
