Dinoflagellate Type Specimens
Figs. 1-6. . Prorocentrum norrisianum sp. nov. FIG.1. Cells are ovate in valve view; the cell surface is smooth with scattered pores. FIG.2. Left valve margin at the anterior end is flat or inclined with a distinctly marked collar (arrowheads). Large pores (large arrows) and small pores (small arrows) are present on the valve surface. Large pores are round with a smooth edge; small pores are indented. FIG.3. Cell's anterior end is flat. The intercalary band is smooth (arrowheads). FIG.4. Periflagellar area is V-shaped, located on the right valve; it has a flagellar (F) and an auxiliary (A) pore, unequal in size. The two flagella are not present. FIG.5. Flagella, the longitudinal (arrowheads) and transverse (arrows), emerge from the flagellar pore. FIG.6.A short, tubular, peduncle-like structure (arrow) protrudes from the flagellar pore (F). The auxiliary pore (A) is to the left of the flagellar pore.
