SuTER. — List of New Zealand Mollusca. 255 



In the meantime, I may repeat that as regards the parietal 

 eye the early stages of development agree exactly with those 

 of bony fishes^ while, as regards the foetal membranes, there 

 is an equally striking agreement with the Chelonians (tm-tles 

 and tortoises), to which group some of our most eminent 

 zoologists — e.g., Boulenger — have long supposed the Tuatara 

 to be closely related. The views of these authorities have 

 received startling confirmation from the study of the develop- 

 ment of the Tuatara. 



Considering the evidently close relationship of the Tuatara 

 with the turtles and tortoises, it seems almost certain that 

 some trace of the parietal eye, which is so strongly developed 

 in the former, will also be discovered in embryos of the latter 

 group ; and this is a point to which I would venture to direct 

 the special attention of embryologists.
