344 D. C. Eaton — Algce from Eastport, Maine. 



fathoms of water. As the stem was freshly cat, and the frond not 

 water-worn, tlie plant must have grown at this great depth. 



7. Laminaria longicruris, De La Pyiaie. 



Common, but none were seen at Eastport of very great size. Grand 

 Menan, 20 feet long. Prof. Verrill. A small but well characterized 

 specimen was found by me in November, 1872, at Old Lyme, Con- 

 necticut : I believe it had not before been observed south of Cape 

 Cod. 



8- Laminaria saccharina, Lamouroux. 



Common with the last, at and below low-water-mark. Among the 

 specimens is one with a third lamina, or half-frond, somewhat nar- 

 rower than the others, but running the whole length of the frond. 

 Near the edge of one of the broadest wings are slight indications of a 

 fourth wing. This explains the little known i. trilaminata of Mr. 

 Olney, and shows it to be only a case of accidental deduplication or 

 transverse chorisis. Tlie specimen is about two feet long and six 

 inches wide at the base, the stem slender and scarcely two inches long. 



9- Agarum Turneri, Postells and Ruprecht. 



Abundant, growing with the common Laminarias, also dredged at 

 20-25 fathoms by Prof Verrill. 



10. Chorda Filum, stackhouse. 



Common in Eastport harbor, from one to many feet below low- 

 water-mark. 



11. Chorda lomentaria, Lyngbye. 



Abundant about the piers and wharves of the town, and at Dog 

 Island, etc., mostly uncovered at low water. Some of the fronds are 

 two or three feet long, half an inch in diameter, and often very much 

 spirally twisted. 



12. Chordaria flagelliformis, Agardh. 



Very common in tide-pools and between tide-marks, assuming a 

 great variety of forms. Var. minor, Agai'dh, is plentiful, especially 

 in a great tide-pool at Dog Island. It is a profusely branched j)lant, 

 with very slender branches, and might very easily be mistaken for 

 Dictyosiphon fceniculaceus. Only very careful microscopic study 

 will avail to distinguish them. 



13. Elachista fucicola, Fries. 

 Common on Fueus, Prof Verrill.
