T. dromedarii Pellegrini, 1945. - metacestodes Intermediate hosts: Arabian camel (Camelus dromedarius), cattle (Bosprimigenius), goat (Capra hircus), zebu (Bos indicus), Abyssinian duiker (Cephalopusgrinui abyssinicus). Geographical distribution: from East Africa to Somalia and India. It differs from T. kotlani in the number of rostellar hooks (34-44), as well as in the size and location of the metacestodes. They are smaller, 2 to 9 mm in diameter (rarely cysts are 8 x 20 mm in size under the visceral pleura). The cysts were found, like T. ovis ((Cobbold, 1869) Ransom, 1913) metacestodes, in deeper layers of different organs. The metacestodes were recovered from muscle, heart, tongue, brain, spleen, lung (rarely), kidney, liver (wild goat) and intervertebral discs (zebu). Pellegrini (1949) supposed that Cysticercus dromedarii is the bladder-worm of T. hyaenae and experimentaly infested hyaenas with Cysticercus dromedarii, derived from Arabian camel. At the same time the adult taeniids might be identified as T. crocutae Metjlck et Beverly-Burton, 1961. The hooks are 34 to 44 in number, 0.187 to 0.212 and 0.112 to 0.137 mm in length; the number of uterine branches is 24 to 30, and the distribution of testes corresponds to that seen in T. crocutae (Fig. 6 D). Thus, according to Vers ter (1969) the above-mentioned assumption of Pellegrini cannot be substantiated. Taenia hyaenae Baer, 1926 Definitive host: brown hyaena (Hyaena brunnea), South Africa, probably intermediate hosts are impala (Aepyceros melampus) and sable antelope (Hippotragus niger). T. hyaenae can be distinguished from all related species by the distribution of the testes (280 to 300 in number), which are extended from the anterior end to the posterior margin of mature segments and confluent posterior to the vitellarium as well (Fig. 6 E). The vaginal sphincter is well developed (Fig. 7 B). T. kotlani differs from T. hyaenae in measurements of the rostellar hooks, which are smaller than those of T. hyaenae. There is a strongly bifid guard for T. hyaenae. According to the original description of Baer the large hooks are 0.202 to 0.223 mm long (mean 0.209 mm), the basis is 0.147 mm long, the small ones are 0.128 to 0.159 mm long (mean 0.143 mm), the basis is 0.083 mm long. In spite of the above-mentioned differences there is a similarity between the two forms. T. parenchymatosa Pushmenkov, 1945 Intermediate hosts are wild ruminants. This species has little metacestodes under the visceral pleura of the lungs and the liver as well. The rostellar hooks are the biggest and the guard shows the strongest growth among the above-mentioned taeniids (Fig. 5). The adult individuals have a vaginal sphincter (see Tables 1 and 2 for review). T. hydatigena Pallas, 1776 (and synonimous Verster 1969) Definitive hosts are Canidae. The widespread metacestodes are situated on the serous membranes of the abdominal cavity in all domesticated and wild ruminants. The rostellar hooks are similar to T. kotlani sp. n., however size and shape of Cysticercus tenuicollis are much larger than that of T. kotlani (Table 1). The handle of the small
