is spinose. The flukes of the first group are relegable morphologically to PANDE'

s type, but on the basis of the measurements the second group stay nearer to the type described by Pande. The exemplars assignable to the first group were dissected from several bat species, whereas the specimens of the second group parasitized two Rhinolophid species only. MACY (1964) discovered and described a new trematode species under the name Pycnoporus ramsesi sp

. n., from Pipistrellus ruppeli in Egypt. On the basis of the description, the measurements and the figures, this species is to be regarded as a junior synonym of Prosthodendrium loossi (Pande, 1935). Prosthodendrium robustum sp . n. - (Pigs. 5, 13, 14) Host: Myotis muricola (Gh.) - Localization: intestinum, Intensity: 2 exemplars. Measurements (in^u): Body length: 800-1000; greatest width: 592-730; oral sucker: 128 x 89 and 132 x 115; ventral sucker: 96 x 128 and 208 x 192; left testis: I6O x 102 and 192 x 176; right testis: 160x112 and 256 x 176; ovary: 138 x 99 and I60 x 160; prostatic complex: 224 x 179 and 198 x I4O; eggs: 19-22 x 9-12 . Diagnosis: A medium-sized trematode with pyriform body. Integument spinose. Oral sucker subterminal

. Oesophagus absent. Caeca extending to testes. Pharynx well developed. Sphaerical testes lying behind acetabulum. (Pig. 14 shows a contracted specimen, therefore the position of the organs is not natural

.)Large prostatic complex situated dorsal from acetabulum, its oral part extending into intercaecal area. Genital pore preacetabular

. Ovary postaçetabular

. Ovary rounded, smaller than testes, located postacetabularly

, lateral

.Vitellaria composed of numerous follicles, situated between acetabulum and prostatic complex. Uterus very well developed, of numerous whorls, occupying caudal portion of body. Differential diagnosis: Prosibodenarium robustum differs from all other congeners principially by/its large vitellary
