The relation between the carpal and tarsal bones and the remaining two middle metacarpals and metatarsals remains just the same as it was in the tetradactyle ancestor. The remaining digits do not exhibit any modification by which they receive more ample support from the carpal and tarsal bones, by taking the place formerly occupied by the now reduced and lost lateral dibits. This mode of reduction I call inadajotive, or reduct

The remaining digits do not exhibit any modification by which they receive more ample support from the carpal and tarsal bones, by taking the place formerly occupied by the now reduced and lost lateral dibits. This mode of reduction I call inadajotive, or reduction in which inheritance is stronger than modification. As an instance of this inadaptive mode of reduction, I may point out the foot of Ano- plotherium and Xiphodon. The annexed diagram clearly illustrates. this mode of reduction. The fourth digit does not even take the whole of the unciform, and a part of this bone is still occupied by the useless rudiment of the fifth digit; the third has not ex- tended over the whole os magnum ; and the useless rudiment of the second digit occupies its typical place on the trapezoid,.
