XII. List of Marine Alg^ collected near Eastport, Maine, 

 IN August and September, 1873, in connection with the work 

 OF the U. S. Fish Commission under Prof. S. F. Baird.* By 

 Daniel C. Eaton. 



1. Fucus vesiculosus, L. 



2. Fucus nodosus, L 



Both these species were very abundant on the rocks and wharves 

 everywhere, between tide-marks. No Fucus serratus was fonnd, 

 though diligently sought for. It was found many years ago at New- 

 buryport, Mass., by Capt. Pike (see Harvey's Nereis Bor. Am., Ill, 

 p. 122), and has recently been sent from Pictou harbor, Nova Scotia, 

 by Hev. J. S. Fotder. 



3. Desmarestia viridis, Lamouroux. 



Abundant on the wharves at Eastport, just below low-water-mark, 

 and seen also at Dog Island. 



4. Desmarestia aculeata, Lamour. 



Even more common than the last, ])rincipally the aculeate form. 

 The pencilled form, however, was found by Mr. Prudden. 



5. Alaria esculenta, Grev. 



Very abundant on rocks just below low-water-mark at Dog Island, 

 and probably equally common in most similar places. — The shape of 

 the pinnje is varible, even on the same plant. One large specimen 

 has obovate pinnre five inches long and three broad, as those of ^. 

 Pylaii should lie, but the base of the frond, so fir from being cuneate 

 and decurrent, is broad and rounded. 



6. Laminaria dermatodea, De La Pyiaie. 



Dog Island, uncovered at extreme low-water. One specimen was 

 brought up by the dredge off Campobello Island in twenty-five 



* I was at Eastport Aug. 12-17, collecting most of the time. Mr. T. M. Prudden 

 and Mr. John B. Ishara collected many specimens, both before and after my visit. 

 Professor and Mrs. Verrill made large collections after I was at Eastport, and Dr. 

 Edward Palmer collected a few species on Grand Menan. All these collections were 

 placed in my hands for study. D. C. E.
