On the structure, development, and morphological interpretation of the pineal organs and adjacent parts of the brain in the tuatara ( Sphenudon punctatus )

The memoir of which an abstract is here given contains a detailed account of the pineal organs and associated parts of the brain in Sphenodon, from the morphological, histological, and embryological points of view, accompanied by numerous illustrations, and may be regarded as a continuation and amplification of my earlier work on the subject. The material upon which my results are based consisted partly of a number of adult living Tuataras presented to me by the New Zealand Government, the cost of transmission of which to England was defrayed by a grant from the Government Grant Committee, and partly of specimens (chiefly embryos) preserved by myself while in New Zealand. I defer the expression of my thanks to the numerous friends who have helped me in the work until the publication of the complete memoir.
