It is impossible in tables, or in any manner 07i a plajie, 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 Manopora3 (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 SideroporfB, 

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

 Favositidse, the Seriatoporse of which appear to lead the way to the 

 Oculinse. The Porites, through the GonioporfB, graduate into the 

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

 porfe on the other. The Madreporse also pass into the Gemmiporge, 

 and likewise into the Dendrophyllise, 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 Actiniae, 

 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.
