STUDIES ON CILIATED CELLS 235 



shaped basal bodies at the distal margin of the cell; Brasil ('04) 

 has found m ciUated cells of the middle intestine of Lagis coreni, 

 rod-like corpuscles, termed 'La batonnet cilifere,' which, to my 

 mind, are not special rods, but correspond with the intracuticular 

 portions of the cilia. 



As to the cihated cells of the gills of Anodonta, my observa- 

 tions are in accord with those of Wallengren ('05) and Erhard 

 ('10). 



The basal corpuscles in the ciliated cells of the Amphibian 

 pharynx are, so far as can be seen from my materials, extremely 

 small, often appearing in profile as a dark line beneath the 

 cuticle, a feature which has been already noticed by Lenhossek 

 ('98). In all of my preparations which are stained to varying 

 extents, I have not been able to make out rod-like or dumb-bell- 

 shaped basal corpuscles in the cuticle, as described by Eimer 

 ('77) and Studnicka ('99) in the pharynx of Salamandra, by 

 Gurwitsch ('01) in the oesophagus of Bufo, and by Tschassowni- 

 kow ('13) in the oesophagus of the axolotl. I am not quite sure 

 whether this difference is due to the materials used or to other 

 factors. 



2) Dumb-bell-shaped or diplosome-like basal corpuscles. 

 These are situated (a) in the crust, as in the cihated cells of 

 efferent tubules of the mouse and rat (figs. 84-88); {b) in the 

 cuticle, as those of the Amphibian epidermis (figs. 31-33); (c) 

 beneath the striated cuticle, as in those of tela of Amphibia 

 (figs. 37-38). 



In the cases (a) and (b) the upper granules are easily decolor- 

 ized, thus giving rise to the appearance similar to that described 

 under 1). 



Regarding the basal corpuscles in the ciliated cells of the 

 efferent tubule, I refer to the papers of Lenhossek ('98), Henry 

 ('00), Ach ('02), Fuchs ('02, '04), and Ikeda ('06). Of these 

 authors, Lenhossek, Henrj^ and Ikeda have found oval or short 

 rod-like basal corpuscles, while Fuchs noticed, in addition to 

 these, diplosome-like bodies. 



My observations on the tela epithelium are entirely in accord- 

 ance with those of Studnicka ('99, '00) on the ciliated ependyma 

 cells of Cyclostoma, fishes, Rana, Salanandra, and of man, and
