Fig. 19 - Anterior end of an unpressed specimen of G. pseudotropii,
cleared in creosote.
Fig. 20-Three hooks from the rostelllun.
Fig. 26- Flattened rostellum with its muscular apical organ and
crown of hooks.
Figs. 27-28- Longitudinal sections through the head end showing
the structure of the apical organ and the suckers. 
Fig. 21-Photomicrograph of a mature segment, feebly pressed;
testes in two irregular rows; uterus a thin median tube.
Fig 22 - Photomicrograph of a flattened proglitttid, commencing to ripen; shows the characteristic vitellaria, the convoluted vas deferens (seminal vesicle and the widened extremity of the uterus owing to reception of eggs.
Fig 23 - Photomicrograph of an isolated ripening segment showing the origin of the uterine diverticula. The globular egg-ejector is seen behind the isthmus in this as well as the previous figure.
Fig 24 - Photomicrograph of a detached gravid proglottid showing uterine diverticula with some eggs and the rupture of the ventral body wall.
Fig 25 - Photomicrograph of a transverse section through the neck to show the caticular spines, scattered bundles of longitudinal muscles and the excretory canals.
Fig 29 - Photomicrograph of transverse section through a mature proglottid
Fig 30 - Photomicrograph of an advanced gravid proglottid to show the development of some eggs into the oysticerous stage.
Fig 31 - Photomicrograph of a flattened mount, in the region of shell gland, indicating the inter-relations of the female ducts.
