Extract

Within the last twenty years our knowledge of the structure and distribution of the armoured Placodermi (including Arthrodira, Ptyctodonta, Phyllolepida, Macropetalichthyida, Rhenanida, and Antiarcha) has increased tremendously. The writer is engaged on a morphogenetic analysis of the group, early publication of which is uncertain. A recent paper by Gross (1941) deals among other matters with the nature of the Antiarch pectoral limbs, and since my own conclusions partly support and partly oppose his very interesting hypothesis, it seems desirable to discuss separately the nature and possible evolution and morphogenesis of these unique vertebrate appendages. To do so it is necessary to review the paired limbs of other placoderms and of Acanthodii, with special reference to their functional significance.
