Young scyphistoma. d. Intermediate, 8-tentacled scyphistoma. e. Fully developed scyphistoma. Scale bars = 250 ^m. as few as two and as many as six, appeared near the distal end of the bulbous calyx. They were filiform with scattered nematocyst batteries, and occurred in one whorl. The oral disk was largely occupied by a prominent, dome-shaped proboscis. The mouth, round or irregular in shape, was capable of considerable dilation. The color was translucent-whitish. Intermediate scyphistomae (Fig. Id) were mm high and bore eight very contractile tentacles. These were filiform with scattered nematocyst batteries, and occurred in one whorl. The stalk was slender, and the cuticle originally enclosing the stalk had become vestigial. The calyx was cone-shaped. A large, flexible, dome- shaped proboscis occupied most of the oral disk, which bore four peristomial pits. The expansible mouth was round, irregular, or quadrate, and the pharynx was quadrate. The color was translucent-whitish, but the endoderm became light orange after digestion of Anemia. Fully developed scyphistomae (Fig. le) attained about 2 mm in height from pedal disk to mouth and bore about 16 filiform tentacles. Tentacles were contractile, in one whorl, and had scattered nematocyst batteries. The moderately thick stalk was somewhat variable in length and merged almost imperceptibly with the cone- shaped calyx. The proboscis was large, flexible, and dome- or knob-shaped. The mouth continued to be expansible, and was round, irregular, or quadrate in Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole,
