CYTOPLASMIC STRUCTURES IN THE SEMINAL EPITHELIUM OF THE OPOSSUM. 81 



Ballowitz's "Centrophormien," and to Heidenhain's "Centralkapsel." More com- 

 plete bibliographical data will be found in Duesberg (1914) and also in Kuschake- 

 witsch and Terni. In recent times the same body has been called frequently "Golgi's 

 apparatus;" other denominations are "von Bergen's reticulum" (Monti), "forma- 

 zioni periidiozomiche (Terni), "dyctyosomes" (for the fragments during mitosis, 

 Perroncito), "idioectosome" and "idiophthartosome" (Stockard and Papanicolaou) . 

 Kuschakewitsch proposes calling it "Spharotheca" and "Spharosomen" (during 

 mitosis), while the complex formed by the "Spharotheca" and the "idiozome" is 

 designated as "Statosphare." 



Since, as noted above, I have rejected the term "sphere," I can not accept 

 Kuschakewitsch's nomenclature. To these terms, which emphasize the relation- 

 ship between the discussed body and the centers or the idiosome (Centralkapseln, 

 Centrophormien, formazioni periidiozomiche, idioectosome), the same objection 

 may be raised as to the terms "idiozome" and "centrotheka," for such a relation- 

 ship is not durable. Other denominations, such as "Nebenkern," "von Bergen's 

 reticulum," "idiophthartosome," etc., are obviously bad. Personally, I would 

 prefer the term "Golgi's apparatus," or rather "Golgi's intracellular apparatus" 

 (Golgischer Binnenapparat, as proposed by Nusbaum), which is already very 

 widely used and does not prejudge any special morphological appearance. The 

 only difficulty is the one emphasized above, when discussing Monti's conclusions.
