from each other. This feature is not typical of T. "hydatigena II". The large hooks of T. pisiformis and T. "pisiformis" show different positions; at the same time, their small hooks are situated close to one another. T. selousi and T. "selousi" have also been found next to each other. Taking the above-mentioned facts into consideration, four other Taenia spp. may be described. Taenia sp. (originally described by Mahon (1954) as Taenia regis, No.: MHNG-94/47) Intermediate host: unknown Definitive host: Panthera leo massaicus (Syn. Panthera leo azandicus) Description: On the basis of the large and small hooks, it can be separated from T. regis and all other species. The small hooks are 197 to 212 pm (mean: 205) long (TL), PCL 126 to 144 pm (mean: 139), ACL 110 to 121 pm (mean: 116), BL 85 to 95 urn (mean: 88), BAL 102 to 124 u

m (mean: 117), GL 71 to 89 urn (mean: 76), TW 104 to 115 urn (mean: 111), PEL 39 to 46 urn (mean: 43). Measurements for the large hooks: TL 290 to 313 urn (mean: 306), PCL 200 to 224 urn (mean: 212), ACL 139 to 150 urn (mean: 146), BL 108 to 119 urn (mean: 114), BAL 176 to 295 urn (mean: 191), GL 85 to 96 (mean: 91), TW 118 to 128 urn (mean: 123), PEL 37 to 45 (mean: 39). Its small hooks are more robust, especially the guard and handle, and wider than those of T. regis. The large hooks are extremely large and have larger values in all measurements as compared to those of T. regis. Remark: Unfortunately, except the mount of hooks, there are no more available materials. Taenia sp. (originally identified by Kotlán as T. pisiformis No.: HNHM-7835/132B) Intermediate host: unknown Definitive host: Panthera tigris virgata Description: Scoleces armed are 497 to 925 um long and 719 to 994 urn wide. Suckers are 221 to 411 urn in diameter. Neck present, elongated. The small hooks are 130 to 164 urn, (mean: 148) long (TL), PCL 85 to 95 um (mean: 91), ACL 82 to 101 um (mean: 92), BL 63 to 86 urn (mean: 75), BAL 67 to 81 urn (mean: 73), GL 48 to 58 urn (mean: 53), TW 74 to 85 urn (mean: 81), PEL 27 to 34 urn (mean: 30). Measurements of the large hooks: TL 246 to 258 urn (mean: 252), PCL 154 to 179 urn (mean: 168) ACL 106 to 119 urn (mean: 114), BL 90 to 103 urn (mean: 96), BAL 145 to 168 urn (mean: 156), GL 53 to 68 urn (mean: 62), TW 87 to 100 urn (mean: 94) PEL 30 to 41 (mean: 34). Large hooks have a long handle and a strong guard. Its small hooks are smaller than those of T. regis and T. pisiformis. The large hooks of T. pisiformis have a short and dumpy guard and a longer handle than those of this species. On the other hand, T. regis has a slender guard. Remarks: Gravid and mature segments have not been recovered. T. bubesei, which was misplaced in synonymy with T. regis (Verster 1969), has been described from Panthera tigris virgata (Abuladze 1964). A comparison is given for hooks on the basis of literature in Table 1. The hooks of juvenile tapeforms, recovered from Panthera tigris virgata kept under Zoo conditions, differed from the hooks of T. bubesei (Table 2).
