描述：

Notosolenus canellatus Skuja, 1948. Gliding euglenid, measuring 15-18 microns long, anterior flagellum about 1.5 times cell length, posterior flagellum about cell length. Anterior end with small but obvious collar, posterior end slightly pointed, dorsal face with one median and two lateral grooves but basically convex. Edges of the cell, especially at the posterior end, are thin flanges. Ventrally flattened, occasionally with one fine median ventral groove which could easily be overlooked.
