Abstract: | Summary The adventitial cells surrounding the spermatheca of the reproductive system of Sonorella santaritana (Mollusca: Gastropoda) appear to have an unusual system of vesicles. Electron micrographs of the membranes forming these vesicles show that they have multiple openings to the cell's exterior and that each opening has a pore complex. In addition, secondary vesicles appear to be generated by the primary vesicles. Evidence is presented suggesting that these vesicles represent a previously unreported membrane transport system.Southwestern Medical School and Veterous Administration Hospital Dallas, Texas, USA |
