The nine regions used in the above comparison are not equally well 

 known; the affinity to an intensively studied region like Great Britain 

 is somewhat overstated, that to a less thoroughly studied region, like 

 the Canaries, xmderstated; but some general indications may be ob- 

 tained. Perhaps the most striking is the distinctness of the Bermuda 

 flora, having only 41 per cent in common with Jamaica, and not so 

 much in common with any of the others. Taking the three classes 

 represented, there is only one in which more than half the species are 

 common to another regionj again Jamaica, which has 63 per cent of 

 the Bermuda brown algae. Taking all the regions, the similarity is 

 greatest in the brown algae, least in the green. The affinities of the 

 Bermuda flora are evidently strongest with the Florida-West India 

 region, next with the Mediterranean, and after that with more north- 

 ern localities. New England has probably the least in common with 

 Bermuda of all the regions compared, its slight numerical superiority 

 over the Canaries being probably due to the less thorough exploration 

 of the latter. 



The following list of important stations, with indication of the 

 characters of each, will, we think, be of use to futiu-e collectors; in a 

 region where the coast line is so long in proportion to the surface area, 

 many such stations must exist, but we think we have Hsted the more 

 important ones. 



In this list of stations we aim to conduct our readers around the 

 whole island and point out the places where we have found certain 

 forms of algae most common. Driven in on all sides by the winds 

 one win find abundance of Sargassum natans "gulfweed" of which 

 the farmers make so profitable use as a fertilizer. This grows in mid- 

 ocean and is never found attached to the shores. Other species of 

 the same genus are foimd growing all about the island along with other 

 literal plants. Many other forms such as Uha, Bryopsis, Cavler-pa, 

 Codium, Laurenda, Dictyota, Padina, Spyridia etc. will be found al- 

 most everywhere, and so will not require special mention. We will 

 start from Hamilton, going west to Fairjdand and Grasmere; there 

 we shall find shallow water and abimdance of plants. Breaking into 

 the land opposite Agar's Island is a large bay; as we first come to it 

 on our left we shall find a large growth of mangrove trees among the 

 roots of which in shallow water we will find abundance of the endemic 

 Halymenia hermudensis, the loose, small form. Farther along in 

 front of a cottage is rich collecting ground; another of the new plants, 

 Chondria curvilineata occurs here, and very large masses of Valonia 

 macrophysa; a larger form of the Halymenia was gathered in abimdance
