Note(s): An ultrastructural investigation of spermatogenesis was conducted on the reef-building polychaete Phragmatopoma lapidosa. Spermatogonia are released into the coelomic cavity from small testes which are attached to the walls of intersegmental blood vessels. Spermatocytes and spermatids are connected by intercellular bridges and develop into mature sperm which are of the “primitive” type but which possess highly modified acrosomes. The mature sperm has a long, curved acrosome which consists of three morphological regions including an unusual anterior portion containing a series of parallel, transverse striations, a central collar, and a bulbous posterior region.The final published version of this manuscript is available at http://www.sciencedirect.com/science/journal/00225320 and may be cited as: Eckelbarger, K.
