During the year 1912 I was able to augment the records of Rhizopoda from the Eastern United States, described in a paper read before this Society in April 1912 *, by collections from the following localities: NEW JERSEY.—The Palisades on the west bank of the Hudson River from opposite Yonkers for about 5 miles southward; gatherings from pools, moss, and sphagnum. This district dries up almost completely during the summer, but 99 species and varieties were recorded, including Difflugia oviformis, D. rubescens, Nebela caudata, N. tenella, Euglypha crenulata, E. alveolata var. cirrata, and Cryptodifflugia eboracensis, besides others noticed at greater length below. Englewood and Leonia; gatherings from pools, ditches, etc., and a large swamp forming part of the Hackensack Meadows: from this district 41 species were obtained, including Nebela dentistoma var. lacustris, Euglypha alveolata var. cirrata, and Pseudodifflugia fulva. Princeton; squeezings from water-plants and sediment from Carnegie Lake, sphagnum from a marsh about one mile north of the lake, and gatherings from a pond near Rahway: 57 species were obtained, including Difflugia oblonga var. cornuta, D. oviformis, D. rubescens, D. urceolata, Nebela scutellata, Euglypha alveolata var. cirrata, and Pseudodifflugia gracilis.
