Abstract
A specimen of Cysticercus tenuicollis is described, which contained many daughter cysts in various stages of development. One of these cysts was a well developed daughter cysticercus.The daughter cysts at all stages of development, are lined internally by a distinct cuticle, and have no scolices. The daughter cysticercus, like the parent bladder, has an outer cuticle and a well developed scolex and receptacular appendage.There is evidence for regarding the daughter cysticercus as having been formed from a daughter cyst by a process of evagination of the latter in such a way that the cuticle has come to lie on the outside, rather than by a process of vesiculation of a scolex.The daughter cysts appear to be homologous with the brood-capsules of Echinococcus. They are not strictly homologous with daughter hydatids or daughter coenuri.
