Free-living Heterotrophic Flagellates from Intertidal Sediments of Saros Bay, Aegean Sea (Turkey) Author Aydin, Esra Elif Author Lee, Won Je text Acta Protozoologica 2012 51 2 119 137 https://www.mendeley.com/catalogue/6cf3745c-7fc3-3086-8e0b-e266c329ac0d/ journal article 10.4467/16890027AP.12.010.0514 1689-0027 13192960 Notosolenus canellatus Skuja 1948 ( Figs 1t , 4e–f ) Observation: Cell is pear-shaped, about 15 μm long, dorsally convex and ventrally flattened. The anterior end has a small collar and the posterior end is slightly rounded. Two flagella of unequal length emerge from the flagellar canal. The anterior flagellum is about the cell length and the posterior flagellum is about 0.7 times the cell length. The dorsal surface has three longitudinal grooves; one median groove and two lateral grooves. The ventral surface has a shallow longitudinal median groove. The flagellar pocket is located on the right side of the cell and the nucleus is on the left side. The cell moves by gliding. One cell found. Remarks: Generally, our observations are in accord with the observations of Al-Qassab et al. (2002) . This species resembles N . pyriforme Lee et Patterson 2000 and N. lashue Lee et Patterson 2000 in general appearance, but these species have only one dorsal groove. This species has been previously reported from marine sites in tropical Australia and the Danish Wadden Sea with cell lengths of 12–15 µm ( Larsen 1987 , Patterson and Simpson 1996 , Al-Qassab et al. 2002 ).
