A fundamental similarity existing among the complex reproductive systems of the Nudibranchiata is pointed out and a classification is presented based on the extent of primary and secondary bifurcation of the hermaphrodite duct. Four types of system are indicated, any one of which might conceivably be the phylogenetic derivative of any other. 2. The histology and anatomy of the reproductive system in Embletonia fuscata, a typical aeolid, are given, and the functional implications of the existing anatomical relationships discussed. 3. Some phases of the natural history of reproduction in the Nudibranchiata are discussed indicating that the mass migrations supposed to precede and follow spawning probably do not occur"--P. 638.13398389 bytesapplication/pdfen-USQH1 .A4 vol.66, art.6, 1934Nudibranchia -- Generative organs.Tenellia fuscata.Nudibranchia -- Reproduction.Nudibranchia -- Classification.text
