The Development of Aplysia punctata

Abstract

This work was begun by one of us in the spring of 1909, at the Zoological Station at Naples, when holding the Oxford biological scholarship.1 Owing to various reasons, the chief of which was ill-health, little more was done there than to collect material. It has been completed with assistance in reconstruction of sections and illustrations at Oxford in the department of Comparative Anatomy during the winter 1909-10. We must here express our gratitude to Prof. Bourne for the opportunity he has afforded us, and the encouragement he has given us to complete the work.

Perspectives in malacology

“…These organs are like PMOs in being near the anus, but they mostly are colorless; occasionally, though, they have some pigmented inclusions. Heymons (1893), Mazzarelli (1904), Saunders and Poole (1910), Smith (1967), Thompson (1976:81), and Bonar (1978), among others, believed that these "larval kidneys" are homologous with PMOs, but this seems questionable. Fioroni (1966) pro-visionally distinguished between primary larval kidneys, cephalic larval kidneys, anal or pallial larval kidneys, and other larval excretory organs.…”
