Slender-armed Starfish. — This species is reported as pro- ducing a small number of comparatively large eggs, which develop without free-swimming stages. It is also said to protect its eggs and embryos beneath the peristome until the young star- fishes have reached a diameter of several millimeters. Blood Starfish. — In this species only a few large eggs are produced. These develop into the adult form by a complicated metamorphosis, although, as stated on page 52, the larvae do not swim free in the water.
