G. ANADYOMENA. 189 



scarcely ever found in vegetables ; in short, the regu- 

 larity of its net- work, its form, and the gelatinous sub- 

 stance which covers every part of this singular being, 

 the fibres which attach it to solid bodies, and the total 

 absence of every thing that can give the least idea of 

 fructification, has decided me to place the Anadyo- 

 mena among the Polypidoms. The small nerves or 

 fibres that decorate this marine production, are so 

 elegantly and so regularly disposed, that it may be ^ 

 compared to the finest net-work. 



Its colour on desiccation is a tarnished green. 



It never exceeds three centimetres in height. 



FAN-SHAPED. 



1. Anadyomf.na Jlahellata. Fan-formed, and 

 marked with articulated nerves, forming a regular 

 net-work, resembling lace : a gelatinous substance, 

 which doubtless is polypiferous, covers the whole sur- 

 face of the polypidom. — Plate 14. fig. 3. a. B. 



Mediterranean, but very scarce. 



ANTIPATHES. 



Polypidom tree-formed, simple, or branching; 

 axe horny, generally shaggy, or stuck with small 

 spines, rarely smooth ; rind or exterior polypiferous, 

 gelatinous, slippery, and almost wholly disappearing 

 on desiccation.
