摘要:

SUMMARY AND CONCLUSIONS.The conclusions arrived at in this investigation may, then, be briefly summarized as follows: —1The rods are symbiotic bacteria, which complete their development within the protoplasm ofPelomyæaand are then ejected, breaking down into free “swarmers,” which are ingested by otherPelomyxœ, and recommence the cycle.2The refringent bodies are proteid in nature; they consist of some form of albumin, which is probably a waste product of the metabolism ofPelomyxa; they have a twofold relation to the bacteria, supplying them with a point of attachment necessary for their development, and (probably) also with a source of nourishment.3The pseudopodia ofPelomyxaare not always blunt and lobose, but often exceedingly attenuated and acute, are often reticulate, or anastomosing, and of a different character from any hitherto described for this animal. Classifications based on the lobose nature of the pseudopodia are hereby invalidated.4The division ofPelomyxais of a simple character, in which the nuclei do not play an important part. The only other form of reproduction observed has been, in a single instance, the production of amœbæ, whereby the observations of Greeff and Korotneff are partly, and those of Pénard entirely confirmed.5Under certain circumstances a portion of onePelomyxamay fuse with the protoplasm of a portion of a secondPelomyxa, the inference from this observation beiug that it may prove necessary to regardPelomyxaas a
