the Plate, is a bush, of Callithanmion arbuscula^ 

 which receives its name from the tree-like aspect 

 which it assumes more distinctly than any other of 

 the marine Algce. Behind it, to the right, are the 

 tall and graceful forms, with their crimped edges, 

 of the slender Laminaria pJiylUtis, And below, 

 still to the right, is a branch of Codium tomentosum, 

 distinguished by its light, yiyid green, and the 

 edging of delicate cili^, which have the appearance 

 of a border of paler green, to every branchlet. Still 

 to the right, in the extreme foregroimd, is a broken 

 piece of rock on which plants of the curious Leatliesia 

 Berkley i have grown, like convex kernels of bronze. 

 To the left are the red-violet tufts of the Bangia 

 fusco-ptirpurea^ and behind them, a branch of Bry- 

 opsis pkimosa. 



In Plate III. the bright-green feathery plant 

 in the extreme background is JEctocarpus silicu-

 Nemaleon multifida. The large, gracefully-bending 

 frond of rich purple, with narrower and younger 

 fronds springing from the same root, is Borphyra

 of our marine Algce^ with which, in combination 

 with other plants of suitable contrast, the vegetation 

 of the Aquarium may be rendered truly splendid, if
