THE FAMILY AQUARIUM. 



The Dumantia filiformis may be recognized by its tufts 

 of lively green. 



The Edocarjpus siliculosus is a bright green, feathery- 

 shaped plant. The E. tomentosus is much closer in form, 

 and resembles a spray of wild broom. 



The Gigartina acicularis is a dark brown, verging on 

 black, and were it exaggenated and placed on the head 

 of a buck, would pass very respectably for antlers. 



The Gracilaria confervoides, with its purple branchlets, 

 is graceful and curious. 



The Hildebrandtia rubia grows on pebbles and rocks, 

 and rejoices in a garb of brilliant red. 



The Iridcea edulis is known by its soKd, deep crimson, 

 or dark-brownish scarlet fronds, looking, at times, like 

 red morocco cut into pear-shaped pieces. It is easily 

 g||prn, and amid the waves its smooth leaves are soon made 

 rugged. 



The Laurencia pinnatifolia and L. pinnatifida are 

 found in tufts, with cut leaves, and a pointed outline, 

 occasionally of a deep yellow, and occasionally a dull 

 purple hue, as the plant may have happened to grow 

 exposed to the sunlight or hidden in the ocean shadows. 

 The sunny colors are the bright ones, of course. 



The Laminaria jphylUtis is seen in clusters, neatly frilled, 

 of deUcately thin texture, and a yellow brown in color, 

 like some fair lady^s ringlets. The L. digitata has a broad, 

 smooth, leathery leaf of dark brown, on a slender stalk, 

 and as it matures, splits into long fingers, or ribbon-like
