. Fresh-water rhizopods of North America. Rhizopoda; Freshwater animals. 88 FEESH-WATEE EHIZOPODS OP NORTH AMEEICA. Some hours later, on examining the same Dinamceba, which had been preserved in the animalcula-cage, it presented the appearance represented in fig. 6, pi. VI. It was oval in shape, mm. long by mm. broad, and sitting, as it were, on a Didymoprium. From the head projected a num- ber of pseridopods. The posterior extremity clasped the alga by means of a transverse cylindrical process of greater length than the breadth of the body. The ends of the process on each side were extensions of the ectosarc fringed with papillae. The cylinder embraced the alga so tightly as to contract its gelatinoid sheath close to its green cellular axis. While watching the Dinamcfiba, without any suspicion of what was to follow, and with the impression that the animal was holding a resting position, as seen in the woodcut 13, the Didymoprium suddenly broke within its clasp, as represented in the following woodcut Successive changes observed in Dinamceba miraMUs while in the act of swallowing a fila- ment of the alga Didymoprium. The animal subsequently passed, through the successive changes seen in cuts 15-21. The Dinamceba gradually shortened, the pseudo- pods in front diminished to two, the two portions of the alga were made to approach each other, and the right side of the body projected in a nipple-like prominence, from which there were suddenly discharged upward of twenty cells of Bambusina (15). These were probably derived from the filament swallowed, as previously described. The cells were nearly all separated, and contained only the shriveled remains of the endochrome. The Dinamceba again became elongated, all pseudopods disappeared,.
