In this last division we have so far adopted the order given in 

 Harvey's Manual of the British Marine Alg^e, but there are several 

 genera and species found in the Bermudas which are not described 

 in that book, and these, too, are among the most beautiful and cu- 

 rious of the class, and are probably of the order Ulvacese ; viz: 

 Anadyomenia stellata ; crisp to the touch ; frond of a circular form, 

 growing in small clusters; of a deep emerald green in the water, 

 a gem of the sea, and of a beauiil'ul stellate celular structure; 

 Anadyomenia Anthrosaccia, a rare plant, consisting of a delicate 

 ■cup-shaped green frond, with radiate tubular cells, set upon a cal- 

 careous stem one and a half inches long. This is the only marine 

 plant that we know of, that assumes the appearance of a terres- 

 trial flower. In its living state it is exceedingly beautiful. 



There is also the beautiful genus Caulerpa or creeping root 

 plants, which abound in deep pools, and on which the Tuitles for 

 the most part feed, viz., C. pilata, two varieties ; C prolifera ; 0. 

 plumosa. Besides these, there are several confervoid plants in 

 our collection which we have not been able to determine. 



These are the ornaments with which the great ocean fringes 

 the land which it embraces. These form the forests, the gardens 

 and. parterres in which the smaller fauna of the ccean delight to 

 ■disport themselves and to hunt for their prey. The dark Oliva- 

 ceous Fucales are many of them also iridescent and glisten 

 in metallic lustre with the brilliant colours of the Rainbow. 

 The Laurencia and the Dictyota form gaidens in retired places 

 of fine shrub-like fronds. The grass-green Uiva has more than 

 the beauty of the richest velvet. The Bryopses with their deli- 

 cate plumes, marginate the rocks at low tide. The clustered 

 and branchy Eucheuma with its blood-red color, and other red
