Contrasting strongly with this we find a lag in growth of the tail region. The curves for measurements of the posterior part of the body (Figs. 11 to 18) are almost mirror images of those for the anterior part. In the graphs of the first two or shorter measure- ments (notch of flukes to dorsal fin, and to anus. Figs. 11 to 14) the lag is less marked than in the two longer measurements (notch of flukes to umbilicus and to ventral grooves. Figs. 15 to 18), so that although the whole tail region undergoes a proportional decrease to compensate for the increase of the head and shoulders, the greatest lag in growth occurs in the region between the anus and the umbilicus.
