Data are given as in original description unless otherwise indicated.
Figs. 1, 2. The two flattened specimens of B. pycnomerus, that of Fig. 2 being devoid of the scolex and some anterior proglottids. x1/2 nat. size.
Fig. 3. Flattened anterior end, with scolex, of the small immature 45mm. specimen. x 17•5 diam.
Fig. 4. Enlarged drawing of the flattened crown of the scolex, with its four armed lappets. x 56.
Fig. 5. Two of the scolex spicules. x 260.
Fig. 6. Dorsal aspect of a portion of the larger 76 mm. worm, in which the segmentation approximately corresponds with the number of sets of genitalia. x 12.
Fig. 7. Ventral aspect of a portion of the 76mm. worm anterior to the gravid segments. x12.
Fig. 8. A portion of the immature (45 mm.) worm showing the lack of correspondence between the external segmentation and the number of sets of genitalia. The crowded condition of the latter can be well seen in this and in Fig. 13. x12.
