摘要：

Pyramimonas grossii is shown to possess up to 4 tubular trichocysts per cell each composed of a rolled ribbon 50Å thick and 0.5 μ wide wound into a flat spiral of 15-25 turns before discharge, and after discharge pushed out into a hollow tube 0.1 μ wide and up to 35 μ long, tapered at both ends. The distribution on the cell and various stages of discharge are illustrated. Comparisons are possible with the larger and more complex trichocysts previously known in the Cryptophyceae. Attention is drawn to the need for further information regarding the taxonomic incidence of such trichocysts among other pigmented flagellates before phyletic conclusions can be drawn. Their functional significance is unknown. © 1969 Springer-Verlag.
