Habit of typical snocimcn of Ilydrocoleum peniciUatum, The more delicate filaments which extend beyond the general mucous mass of the erect branches of the thallus do not appear distinctly in the rei)roducti()ii. The rest of their nearly 800 marine algal names (excluding dia- toms) are either reduced to synonymy or (in a small proportion) apply to varieties and forms also represented by the typical condition. In comparison with, the Florida flora of nearly 420 well authenticated species we have a Guadeloupe flora of about 250 species very probably present, and a residue of about 290 names from which additions will be possible when a review of the original material allows accurate disposition of the re- cords to be made. The descriptions of new species are too inad- eciuate to be of much assistance, and many of the records are very improbable indeed. At the time of the preparatuMi of the Florida algae report it was not possible to analyze suitably the Guadeloupe records, so this opportunity is taken to point out the present state of our knowledge. As was indicated there, the recorded algal flora of none other of the West Indies appears as rich as the coast of Florida. The writer desires to express his indebtedness to Dr. iM. A. Howe of the New York Botanical (;arden for much kind as- sistance and for access to the algal collections of the Garden. The herbarium of John Hooper was examined for Morida algae through the kindness of the Brooklyn Botanic Fig 2 Apex and more median portions of trichomes from Ilydrocoleum peniciUatum, X900, approx. As prepared from dried material the sketch prob- ably overemphasizes the degree of constriction of the at the cell junctures. ADDITIONAI. RKCORKS Hydrocoleum peniciUatum n. sp.
