Character . — Zoarium submembranaceous or corneous, continuous, erect, ramose, 
radicate. Zocecia quadri- or multiserial, disposed round an imaginary axis, and forming 
cylindrical or prismatic branches.

p. 155; Kirchenpauer (pars)? 
Character . — Zoarium furcate or dichotomous ; the angle at each bifurcation occupied 
by a hollow membranous expansion (modified zooecium ?). Zocecia oblong, elongated, 
almost entirely membranous in front, which is depressed or flat, with an acute angular 
border. Avicularia, when present, sessile or subimmersed, placed at the bottom in front. 
Mouth close to the summit, more or less protruded, the oral valve projecting. Ocecia 
cucullate, superior. 
In the Quart. Journ. Micr. Sci. ( loc . cit . ) I described two forms of a corneous texture, 
and formed of cylindrical branches constituted of utricular zocecia, under the generic 
term Farciminaria, following in this, M. Kirchenpauer, to whom I was indebted for the 
specimens. But I am now satisfied that these two forms cannot be placed in the same 
genus with my Farciminaria aculeata, though belonging, as it seems to me, to the same 
family. I would therefore venture to propose that the two species in question should, 
in accordance with my former suggestion, be named Verrucularia, v. Suhr, notwith- 
standing the circumstance that v. Suhr regarded Verrucularia dichotoma as a fucus; 
as which also I believe Dr. Harvey considered Farciminaria binderi of Kirchenpauer.
