.Paulinella indentata n. sp. is described from benthic sandy sediments of Kames Bay, Scotland. The description is based on light and scanning electron microscopical observations. This marine, testate amoeba has filose pseudopodia, sometimes branched, extending up to 50 μ m from the aperture. Tests are oval in outline (c. 15.8 × 9.8 μ m) pale yellow in colour with a short collar. The most important diagnostic feature is the morphology of the surface scales which are arranged in staggered rows. Each cell is covered with around 22 scales (c. 5.7 × 2.9 μ m). Scales are rectangular, curved with rounded corners and markedly indented along their median axis. They have a hollow channel running below each ridge and their surface is punctuated with rows of pores. This is the first isolation of Paulinella from benthic marine sediments.
