xenocypris

[Prefix xeno-, and Mod. Lat. cypris Lat.cyprinus (q.v.).] [XENOCYPRIDINA.] states from those exhibited by the parent and did not return into the cycle of the parent. Profe or Huxley remarks that the proper term for this would be heterogenesis, but that unfortunately this term has been employed in a different sense; and after showing that there are analogies both for and against xenogenesis, decides against its known existence. The nearest approach to it is not, as was once believed, in tapeworms, the history of whose transformations has been traced, but in tumors and corns on the animal body or galls on the vegetable leaves or other organs. ( Prof. Huxley : Presidential Addre , Brit . A oc . Rep ., 1870.) "I have dwelt upon the analogy of pathological modification which is in favor of the xenogenetic origin of micro zymes."- Huxley : Presidential Addre , Brit. A oc. Rep. for 1870, p. lxxxv.
