Glaucus; Or, The Wonders of the Shore

FLUSTRA LINEATA. Pl. I. fig. 1. In Flustræ, the cells are placed side by side on an expanded membrane. Fig. 1 represents the general appearance of a species which at least resembles F. lineata as figured in Johnston’s work. It is spread upon a Fucus. Fig. A is an enlarged view of the cells. FLUSTRA FOLIACEA. Pl. I. fig. 2. We figure a frond or two of the common species, which has cells on both sides. It is rarely that the polypes can be seen in a state of expansion. SERIALARIA LENDIGERA. Pl. I. fig. 10. NOTAMIA BURSARIA. Pl. I. fig. 11. The “tobacco-pipe”“ appendages, fig. 11 B, are of unknown use: they are probably analogous to the birds’ heads in the Cellularæ.
