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 Manopora? (table 3), and 

 from these into the Alveoporse, is almost a direct line ; from the 

 last, the line branches either way into the Porites and the Sideroporae, 

 and the Sideroporse pass into a network of species of the family 

 Favositidae, the Seriatopora of which appear to lead the way to the 

 Oculinaa. The Porites, through the Goniopora?, graduate into the 

 Astraoporae, and thence to the Astroites on one side and the Gemmi- 

 pora? on the other. The Madrepora? also pass into the Gemmipora?, 

 and likewise into the Dendrophyllia?, 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 Actinia?, 

 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.
