They form an integral part of the pelvis, and in the embryo are seen to be in direct connection with its cartilaginous symphysis ; but later on articulations are formed between them and the pubes. There can be no doubt that these structures are the homologues of the epipubis of lower Vertebrates, which has been retained in non-placental Mammals in order to serve as a sup- port for the abdominal walls in connection with the marsupial pouch (p. 28)..
