ceous, mostly forked, ultimate ramuli, which are more crowded towards the 
summits. Vesicles not known. Receptacles formed from the uppermost 
ramuli of the smaller branches, hence always crowded about the apices, 
constricted into bead-like nodes, each node containing a scaphidium. 
Colour a dark olive, turning black in drying. Substance coriaceous, tough.

A “ Cystophora,” without vesicles, is as anomalous as the play 
of ‘Hamlet’ would be with the character of the Prince of Den- 
mark omitted ; and yet, in habit and in the development of the 
frond there is such close accordance with other Cystophore that 
it would be unnatural to separate this species from its congeners. 
Vesicles, in the Fucordee, though very constant where they occur, 
sometimes are present or absent in the same species, and even 
Fucus vesiculosus itself is not unfrequently found without any 
bladders. Usually vesicles are more common in species that 
either inhabit shallow water or that float partially on the sur- 
face. Probably our C. paniculata wnhabits the deeper part of 
the Laminarian zone, where buoys would be comparatively use- 
less to it. Whether its branching root be also an adaptation to 
fit it for a residence among the Lamnari@ is uncertain.
