The latter condition is found also in the Dipnoi (lungfishes). The lung of the mud puppy, Necturus maculosus, is capable of considerable extension, particularly in the antero-posterior direction, is devoid of air cells within, and, hence, probably serves the buoyancy function as much or more than that of respiration. The lungs

METAMERISM 541 derm is complete dorso-ventrally, including the hypomeric region of the mesoderm. It becomes evident, therefore, that the suppression of segmentation in the hypomeric area in the vertebrate embryo achieves a precocious result which the embryo of Amphioxus reaches only at a later period of develop- ment. Presumably in the vertebrate embryo, segmentation of the epimeric mesoderm is retained because it serves a definite end, whereas se
