    There can be no question but that the carpus and tarsus, the metacarpus and metatarsus, and the various digits beginning at the poUex in the one, and the hallux in the other, are really homologous; the circumstance of the con- stant absence of one of the bones of the preaxial digit in both fore and hind limbs is most significant. In the carpus and tarsus, the serial homology of the four bones of the distal row in their respective order is geneially admitted, but with the other bones there is still some differ- ence of opinion. Gegenbaur has, however, given good reasons,^ derived chiefly from the results of tracing both limbs back to their less modified condition in Reptiles and Amphibia, for considering the astragalus as equivalent to the scaphoid and lunar united, or the scapho-lunar bone of the Carnivora, &c.; the calcaneum as representing the cuneiform, and not, as often supposed, the cuneiform and the pisiform (the latter being only a sesamoid); and the navicular of the foot as representing the os centrale, found only occasionally in the man us of Mammals. ^ Untersuchungen zur Vergleiclicnden Anatomic, l*' lleft, Carpus und Tarsus, 1864. 7.
