This specimen (figs. 9, 10, 11, and 12) was studied and published by Dockeray (1915), and his findings have been rearranged and incor- porated into this study. The total prosenceph- alon has attained the enormous weight-value of per cent of the total brain weight, the diencephalon dropping to per cent and the.
