The Chylodadia artiadata is a pretty weed, like a multi-

 in chains." It grows in dense, mossy patches, on the per- 

 pendicular face and overshadowed edges of the rocks. 



The Dorsga elegans, a showy red weed, may be found in 

 all portions of our harbor, from half-tide to low-water 

 mark. When removed young to the tank, it flourishes 

 very satisfactorily. 



The Entomorjpha comj)ressa is also quite common in our 

 bay, and in the vicinity of Long Island Sound. It is a 

 green weed, and grows rapidly in the Aquarium. The 

 E, ramulosa is equally suitable. In form and size this 

 plant exhibits great variations. It is full branched, and 

 much twisted in figure. 



The Gelidewm corneim is a red weed, usually slender 

 and of small size, its leaves fringed with delicate processes 

 all round. It is a hardy plant, and so is 



The Fhyllo'phora, a brilliant red weed. 



The Padina pavonia is a comely plant, fan-shaped and 

 brightly radiated. 



The Polisyphonia arceolata grows in reddish-purple tufts, 

 and presents an agreeable contrast beside the light green 

 or pale yellow leaves of its companions.
