This comparison shows the importance of studying young and old stages of Cirripedes, especially those species with many plates, as in Scalpellum. Broch (1927) discussed the changes in the shape of the capitular plates during the ontogenetic development, a subject also mentioned by Nilsson-Cantell (1921). Accessory parts are added to the primary parts. A comparison is made by Broch between different species of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Institute of Oceanographic Sciences (Great Britain); National Institute of Oceanography; Great Britain.
