 Fairyland, Dec, Collins; in tufts on wall by Palmetto Vale, Harring- 

 ton Sound, March, Hervey. In the North Shore and Fairyland 

 stations there were scattered filaments only, imperceptible except on 

 microscopic examination. At the Sound station the tufts were sev- 

 eral cm. long. In all cases it was a slender form, mostly monosi-

 May, Kemp, unnamed specimen in herb. ; on mangroves below Flatts 

 Bridge, April, May, Collins; Ely's Harbor, May, Hervey. At Flatts 

 Bridge the Porphyra began to be visible about April 20, 1912, growing 

 on mangroves in company with Monostroma latissimmn; both minute 

 when first observed, but growing rapidly up to May 3, when we left 

 Bermuda. When next at this place, from July to Sept., 1913, the 

 Porphyra was not to be found. The Ely's Harbor plant is of moderate 

 size, up to 6 cm. long; the specimens in the Kemp herbarium reach 

 10 cm. in length. P. vulgaris of Moseley is undoubtedly this species.
