EXPLANATION OF PLATE XLL 



[All the figures have been reduced to one-half linear from the originals drawn 

 by Mr. P. Highley.J 



The figures are arranged in four vei'tical columns representing the four 

 supposed genetic series — the columns to be read from bottom to top. The 

 corresponding morphic equivalents in each series are to be seen by reading 

 horizontally. Figures enclosed in rectangles do not belong to the actual genetic 

 lines, but are illustrative of certain developmental stages. 



Figs. 1-9. Aniinomia. 

 Grlossothyridoid Stage.

 valve, with sulcus; b, anterior margin, with linguiform median lobe
