Abstract

Callorhynchus capensis Dumeril is a fairly common South African representative of the Chimaeroidei. According to Smith these holocephalans may be found from the surfzone to a depth of 183 metres right around the South African coast. The exact phylogeny of the chimaeroids is obscure due to difficulties encountered in obtaining embryological and fossil material. Stensio and Orvig believe that the ptyctodonts gave rise to the Holocephali, whereas Moy-Thomas and Patterson are of the opinion that the Holocephali and ptyctodonts diverged from a common prearthrodire ancestor. The reader is referred to Patterson who provides a comprehensive review and new ideas regarding chimaeroid phylogeny.
