✦ Synopsis

The structure and cell types of the closely simiIar glands of Calamoicht h y s and PolypteTtcs are described and a general comparison made with the teleost pituitary. The Polypterine gland shows some unusual features in the anatomical disposition of its parts and i n the arrangement of its neurosecretory and vascular supply and an explanation of these differences is suggested, based on relative growth changes in later development, i n order to include these glands in the evolutionary pattern of the actinopterygian pituitary.
