G. ANADYOMENA.

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. Anadyomena Jiabellata. 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.
