Figures 30 to 32. Schizotaenia variabilis. Fig. 30. Mature proglottid, dorsal view. After this drawing was completed the study of additional material showed that it is not normal in some respects, namely: (i)-the testes are usually further forward, anterior to the transverse commissure; (2) the accessory ventral commissures were found in only one specimen; (3) the vesicula seminalis is usually not thrown into wide curves as here shown. The uterus may be somewhat more extensive than here shown; the
poor condition of the material does not permit exact judgment as to the limits of this structure. Fig. 31. Diagram of excretory system of five adjacent proglottids, showing
accessory transverse commissures (AVC) and other features. The absence of the main transverse commissure in some cases may be due to the fact that the proglottids are not fully mature. Fig. 32. Drawing showing the cloaca only partly everted and the cirrus pouch lying consequently mostly mediad of the excretory ducts.
