Authors almost invariably figure the shell-gland of Cestodes in a form resembling that of a daisy's corolla. This may serve to indicate the position of the shell-gland but it should be remembered that the shell-glands are not all of this form. Thus, the shell-gland shown in Fig. 1 is somewhat shrub-like in form, consisting of irregularly fusiform elements which grow filamentous at one end and they are clustered on one side of the ootype of the uterine duct. The nucleus is situated in the fusiform portion and the filamentous portion extends toward the parenchyma of the cortical layer.
