On the development of the frog, Leiopelma hochstetteri Fitzinger

Authors


Summary.

The development of the chondrocranium and visceral arches of Leiopelma hochstetteri Fitzinger is described.

The more important, basic developmental features of the genus, which were first noted in L. archeyi Turbott, are confirmed, while specific differences are indicated.

Additional evidence for the theory (Stephenson, 1951 a) of the hyoid nature of the basal connexion between the quadrate and the neurocranium in amphibia is presented and discussed.
