BANGIA? CERAMICOLA, Claw. 
Gen. Cuar. Frond filiform, tubular, composed of numerous radiating 
cells, disposed in transverse rows, and enclosed within a hyaline, con- 
tinuous sheath. Spores purple or green, one formed in each of the 
cells of the frond. Banera (Lyngd.),—in honour of Hoffman Bang, 
a Danish naturalist and friend of Lyngbye. 
Baneia ceramicola ; filaments parasitical, very slender, flaccid, elongated, 
rosy ; articulations once or twice as long as broad, longitudinally 
striate ; the endochrome “ at length globular and escaping through 
the broken tube.” (Carm.)

Descor. Filaments about an inch or an inch and a half in length, attached at 
base, floating in the water like tufts of fine floss-silk, extremely slender, 
but not of equal diameter, some filaments being twice as broad as others, 
unbranched, articulated. Articulations either as long as broad, or, more 
commonly, twice as long, slightly constricted at the dissepiments, the 
endochrome finely striate longitudinally, and apparently consisting of 
radiating cellules placed side by side ;—but the exact structure not easily 
seen after the plant has been dried, im which state, only, have I seen it, and 
I have not succeeded in getting a transverse section. Sometimes (as at 
fig. 3) the articulations appear empty; the endochrome having escaped. 
Colour a beautiful rosy red. Substance delicately membranaceous. In 
drying, the plant adheres closely to paper.

Our figure is taken from a specimen communicated by the 
Rev. D. Landsborough, and exhibits the characters of the plant, 
so far as it is possible to arrive at them from a dried specimen.
