. Fig. 2. Scalpellum gibberiim. a, b, c. Young specimens (total lengths 2-30, 4-30, and 11 mm. respec- tively), d. Full-grown specimen, lateral view (total length 30 mm.), e. The same specimen, rostral view. 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
