The relation at different depths between the crinoids 

 in which the disk is not radially symmetrical and those in 

 which it is radially symmetrical is shown in the table on 

 page 542 and in Fig. 6. 



The relation at different depths between the crinoids in 

 which one or more rays are dwarfed, or, more rarely, en- 

 larged, and those in which all of the rays are of the same 

 size is shown in the table on page 543 and in Fig. 6.

The relation at different depths between the crinoids 

 with more (less frequently less) than five rays, and those 

 with five ravs, is shown in the table on page 544 and in 

 Fig. 6. 



The relation at different depths between the crinoids 

 with three basals and those with five is given in the table 

 given above and in Fig. 6.
