Text Appearing Before Image:
CHORDATE KIDNEYS Fig. 77. A diagram illustrating the four types of kidneys which occur in chor- dates. The excretory tubules in Amphioxus are ectodermal in origin like the proto- nephridia of annelids, while they are mesodermal in vertebrates. In the course of phylogenesis the excretory organs of chordates have been successively pronephros, mesonephros, and metanephros.
