Plate 1. Photographs of three embryos belonging to horizon xix

Comparing specimens of earlier age groups with those now being considered, it is seen that the trunk region is beginning to straighten out and the cervical angle is less acute. The coalescence of parts in the branchial region has altered the appearance of the external ear, and the hillocks are less conspicuous. The axes of the arms are almost at right angles to the dorsal line of the body of the embryo. x4.

Figs. 35-37 No. 8092.

Figs. 38-40 No. 6824.

Figs. 41-43 No. 4501.
