Excerpt from The Algae of Bermuda, Vol. 53 We had hoped to publish with the present paper somewhat full comparisons of the floras of Bermuda and other regions, but the list for the Danish West Indies, perhaps the most instructive, is not fully available. We have reluctantly had to omit from our list the families Rhizophyllidaceae, Squamariaceae and Corallinaceae; with out careful study of the types any conclusions in these critical families would be uncertain, and in the present European conditions such study has not been practicable. In view of this we have made only a short statement, by classes, Showing the percentage of the Bermuda species common to nine of the best known regions where a similarity might be expected. If later we are in position to take up the families now omitted, and a full account of the algae of the Danish West Indies is available, the proposed full comparison may be made. In the present comparison we have not included the Class Myxophyceae; first because the species of this class are largely cosmopolitan, second because in many regions where the other classes are fairly well known, the Myxophyceae have been little studied. We have considered a species as common to two regions, though represented by different forms or varieties in each; pelagic species, known only as washed ashore, have not been included.
