The clam lies byssally attached to coral incrusted limestone with its hypertrophied siphons (the whole of the fleshy portion in the figure) fully exposed to the sun's rays. MATERIALS AND METHODS Adult specimens of the tridacnid clams Hippopus hippopus, Tridacna gigas, T. maxima, and T. sqiiamosa (Rosewater, 1965), were collected in shallow coral reef waters at Eniwetok Atoll, Marshall Islands, by free diving or using S. C. U. B. A. Blood samples from the circulatory systems were syringe extracted from the clams' hearts and immediately centrifuged to precipitate a firm easily handled pellet of amoebocytes. One millimeter square cubes of clam digestive gland and the mantle edge inner folds (Hippopus excluded) were cut from tridac- nids and, along with the centrifuged amoebocyte fractions, were treated in one or both of the following ways: Method I—light and electron microscopy 1. Fixed at 0° C for 14 hours in 2% osmium tetroxide buffered with Dorey's solution B (1965). For better penetration and osmotic compatibly of fixative with tissues, potassium chloride was substituted for the sucrose originally pre- scribed in the Dorey formula. 2. Dehydrated and embedded with Epon 812 (Luft. 1961')..
