ABSTRACT. Three new limax amoebae, isolated from marine, surface sediment samples are described using light microscopic and fine structural features. One species, characterized by eruptive locomotion typical of the family Vahlkampfiidae, is assigned the name Vahlkampfia caledonica (47.4 ± 16.0 μm × 12.1 ± 3.2 μm). The other two monopodial species move with steady locomotion characteristic of the family Hartmannellidae. One is a Saccamoeba with a distinct posterior bulbous uriod, vaculoes containing prominent crystals, glycocalyx with cup-like components, and spherical nucleus with central nucleolus. It is assigned the name Saccamoeba marina (72.5 ± 14.9 ±μm × 20. 7 ± 4. 5 μM). The other hartmannellid limax amoeba moves by steady locomotion and has a rather constant monopodial from, lacks a uroid, but has occasional trailing masses of cytoplasm, contains cup-like structures in the glycocalyx, and is characterized μm). Few limax amoebae have been described from marine environment and these data provide additional evidence that limax amoebae may be more abundant in marine sediments that realized previously.
