The first 70 proglottids are very short (10-50 long x 370-530 wide), the next enlarge in size towards 400- 500 x 940-1030. The last 20 proglottids are a bit wider than long 1050-1200 x 1250-1450. In mature proglottids (Fig. 3), genital atrium ventro-submarginal, in anterior half of the segment; genital pores alternate irregularly. Cirrus sac elongate and slender, 80 x 450 in size, directed anteromedially, sac thin-walled; cirrus unarmed and coiled within sac, internal and external seminal vesicle not seen; vas deferens coils medially to mid-line, then posteriorly towards genital complex. Testes of different shape, often ovoid, 70-95 in diameter (55-70 in proglottids 71-160), arranged in a single layer; testes number 80-90 per proglottis, encircle female genital complex and occupy entire medulla except for region of female genital complex and anterior of it. Ovary centrally, follicular, x-shaped with 2 major branches, each 95 x 160. Uterine ducts coiled before they enter the sacciform uterus. Vitelline follicles 25-35 in diameter. Remarks. Dollfus (1960) described larvae of N. africana from the body cavity of Galeoidespolydactylus, Mullus barbatus, Pagellus sp. Serranus cabrilla, and Trigla The 3 scoleces measured by Dollfus were variable in size, ranging for example between 750- 1100 (SL), 397-540 (pbo) and 19-35 (TW). The BR and SP were between :1 and :1 respectively and the hook size in the metabasal armature was between 14-17. The measurements for the present specimens were smaller and only the SP of the specimen from Carcharhinus leucas directly c
