Some of the specimens which I have referred to this species and one of which I have shown in lig. 52 approach most closely to Trentepohlia virgatula Faiiow in »Marine Algæ of New Eng- land«, p. 109, tab. X, lig. 3. The short branches bearing mono- spores are very often opposite and tliose in the upper part of the plant especially terminate in long hairs. Chromatophores are star-like, as may distinctly be seen in the young sporangia. The cells in the long branches are about 10 \i thick. Other specimens differed from these in being almost devoid of hairs, and only after close examination were a few branches found term inating in hairs: these specimens which were gathered near Velbestad epiphytic on Gigartina mamil- losa were further especially noteworthy because they bore both monospores and tetra- spores. As is well-known, Har- vey figures in Phycologia Brit., pi. 313 a Callithanmion virga- tulum bearing monospores as well as tetraspores1, but as is equally well-known this report. Fijr. 52.
