 being indicated in this figure by the dotted line. In this sec- 

 tion one sees the ciliated areas dividing the less specialized, or, 

 as it may be termed, the intermediate epithelium, into a number 

 of bands, a depression between each of these leading down to

 latter do not reach the surface merely owing to the state of 

 contraction of the tissues. 



In Fig. 4 the section passes along the line indicated by DD
