C) The hooks of the two rows different in size, both with handle but the guard does not reach so much forward as in the previous hook types (Figs 5, 6, 14), B. cordifera sp. n. and Biuterina africana Joyeux et Baer, 1928. The handle and the guard are distally thickened in all three types. FREEMAN (1959) recommended the use of the ratio of length/guard to characterise the hooks (total length of hook divided by length of the guard perpendicular to the hook). He noted in connection with the Cladotaenia and Paru

a species that the guard index in the Paruterina species varies between 3. 5 and 4. 0. This index in the species studied by us: B. passerina 1.5-2; B. triangula-2. 0-2. 4; B. cordifera - 2.5-3.2. The measurements of the hooks are summarized in Table 1. Larger study material would permit us to draw more far-reaching conclusions, but based on the evidence we have so far we wish to point out that the shape of the hook is, an important constant specific character.
