are accumulated especially underneath the transparent zone. 

 Ciliated cells with a centrosome and those with two or more 

 nuclei often occur. 



11. The gall-duct of Amphibia. The epithelium of the gall- 

 duct of Amphibia consists of ciliated and non-cihated columnar 

 and basal cells. The ciliated cells (fig. 57) are columnar in shape 

 and bordered with a cuticle, through which the cilia pass to con- 

 nect with the basal corpuscles. These are small granules, situ- 

 ated underneath the cuticle. If, as in a certain degree of differ- 

 entiation is the case, the points where the cilia are connected 

 with the upper border of the cuticle appear as black granules, 

 then the feature of diplosome- or dumb-bell-shaped corpuscles 

 would be brought about. The behavior of the transparent zone 

 and of the rootlets of the cilia is about the same as described 

 in the pharynx of Amphibia. Ciliated cells with two nuclei 

 and those with centrosomes are not infrequent here. 



12. The oviduct of Amphibia. The oviducal epithehum is com- 

 posed of ciliated and glandular cells. The former (figs. 63, 66) 

 have thin cuticular borders; the basal corpuscles appear either 

 as short rods in the cuticle, or as small granules underneath it. 

 This difference of shape may perhaps be correlated partly with 

 the degree of staining, partly with different animals. Thus I 

 have found short, rod-hke basal corpuscles in the oviduct of 

 Triton, whereas they appear in that of the frog as of minute 

 granules underneath the cuticle. In tangential sections they 

 are arranged in parallel rows, all of the granules of one row being 

 united by a fine slightly-staining thread. The direction of the 

 rows corresponds to that of the short side of the distal cell-border 

 (fig. 67). The chondriocontes are mainly gathered under the 

 cuticle, the transparent zone is illy defined; binucleate ciliated 

 cells often occur. 



13. Ciliated cells in the peritoneum of Rana temporaria. The 

 occurrence of ciliated cells in the peritoneum of female frogs was 

 first described by Thiry ('62), and then confirmed by Schweiger- 

 Seidel and Dogiel, Neumann, Nussbaum and others. According 

 to these authors the ciliated cells in question are flattened and 

 are smaller than neighboring endothehal cells ; they are either
