Petalomonas minuta Hollande, 1942 (fi gures 14e, 15m) Description. Cell outline ovate, 6-10 Mm long (mostly 6-7 Mm), 4-6 Mm wide, fl attened, with a deep longitudinal groove on the dorsal face. One cell had two indistinct ventral ridges which were hard to see, and two cells had a narrow ventral groove-like slit. With one fl agellum inserting into a reservoir in the right-hand side of the cell, fl agellum about same length as the cell. The nucleus is in the left-hand side of the cell. Glides. Often common. Description based on observations of 16 cells. Remarks. This species was fi rst described as P. mediocanellata var. pusilla by Klebs in 1893.

Because of the principle of co-ordination of the ICZN (Article 46) P. pusilla Skuja 1948 is a junior homonym. The same organism as observed by Klebs was described by Hollande (1942) as P. minuta. Although the correct name for this species under the provisions of the the ... : Published as part of Lee, Won Je & Patterson, David J., 2000, Heterotrophic flagellates (Protista) from marine sediments of Botany Bay, Australia, pp. 483-562 in Journal of Natural History 34 on pages 521-523 ...
