Abstract

Thanks to the most generous and freely rendered services of Mr P. Henaghan, Principal Keeper of the Lighthouse on Stephen’s Island in Cook Straits, I have lately obtained a very perfect series a Tuatara embryos, ranging in age from just before the appearance of the blastopore to about the time of hatching.
