It is impossible in tables, or in any manner on a plane, to give a 
correct and complete idea of all the interlinkings of genera; circles 
give a regularity to the reticulations, which is not found in nature. 
The passage of the Madrepores into the Manopore (table 3), and 
from these into the Alveopore, is almost a direct line; from the 
last, the line branches either way into the Porites and the Sideropore, 
and the Sideropore pass into a network of species of the family 
Favositide, the Seriatoporee of which appear to lead the way to the 
Oculine. The Porites, through the Goniopore, graduate into the 
Astreopore, and thence to the Astroites on one side and the Gemmi- 
pore on the other. ‘The Madrepore also pass into the Gemmipore, 
and likewise into the Dendrophyllie, which two groups are closely 
allied though distant in the table; the four lines thus meet in the 
Caryophyllia family, the genera of which have their principal grada- 
tions, as shown above. By a study of the other tables, the relations 
of the groups will be made out without particular explanation. The 
Actinaria graduate towards the Alcyonaria, through certain Actinie, 
with four or eight lobed disks. 
The following table contains a general view of the Classification of 
Zoophytes, to which the principles discussed appear to lead, together 
with the characteristics of the several subdivisions.
