! opinion differs too little from Cellularia to be admitted. There is 
certainly much sameness in the characters of these genera, but there 
is a recognizable difference in the form of the cells, more particularly 
in the aperture, liker in Acamarchis to that of Flustra than of Cellu- 
laria, which warrants us in laying hold of it as a line of separation in a 
case where the dissimilarity in habit is very obvious. The agree- 
j ment in this respect between the species seems no less patent, al- 
j though it has not been hitherto perceived. 
Farcimia,* Fleming. 
Character .-— Polypidom rooted , plant-like , calcareous , di- 
chotomous ; the branches cylindrical , regularly jointed , with im- 
mersed rhomhoidal cells diverging from the axis , disposed in quin- 
cunx , and opening on the surface ; the apertures lateral , plain , 
non-operculate. 
1. F. salicornia, articulations nearly cylindrical ; the cells 
rhomhoidal , plain.

One of the finest of British zoophytes. Polypidom from 1 to 3 
inches high, white, calcareous, fibrous at the base, erect, regularly 
dichotomous ; branches erecto patent, straight ; joints constricted, 
* From Farcimen — a sausage, in allusion to the manner in which the inter- 
nodes are joined. The genus is synonymous with the Cellaria of Lamouroux, 
and with the Salicornaria of Cuvier, Reg. Anim. iii. 303.
