The scales of the mormyrid fishes with remarks on Albula and Elops

These fishes all have scales of the same general type; cycloid with well-developed circuli and with strong basal radii. The truly remarkable feature is found in the apical radii, which are greatly modified and join irregularly, forming a network, as is well shown in the accompanying drawing by Miss Evelyn V. Moore (figure 1). The apex of the scale is usually broad and blunt, or even subtruncate, while the base is more pointed and narrower.
