this country, the earlier record having been from the New Hamp- 

 shire coast, so that a marked extension of range is indicated. 



Porphyra atropurpurea (Ohvi) DeToni (Taylor 1937b, p. 

 220). Glen Cove, 1 May 1938. Apparently this plant has not pre- 

 viously been reported from Long Island. 



Porphyra nuibilicalis (L.) J. Agardh. (Farlow 1881, p. Ill as 

 P. laciniata). Lake Montauk; Glen Cove. 



Bonnemaisoniaceae 

 Asparagopsis hamijera (Hariot) Okamura. (Taylor in Lewis 

 and Taylor 1928, p. 197; 1937b, p. 244). Buoy off Lake Montauk, 

 17 May 1938. Apparently this plant has not previously been re- 

 ported from Long Island, but has been known from the Buzzards 

 Bay area since 1927. This represents an extension of range for the 

 species. 



Dmnontiaceae 



Diimontia incrassata (Miiller) Lamouroux. (Dunn 1916, p. 

 271 as D. filiformis). Lake Montauk. The writer himself observed 

 this plant in some abundance at Montauk Point, and collected speci- 

 mens 16 June 1936. This plant has apparently not previously been 

 noted from Long Island, but it was reported from Maine in 1916, 

 and later from James Bay. It is known to occur at various stations 

 between Xova Scotia and Rhode Island. , 



CoraUinaceae 

 Corallina officinalis L. Lake Montauk. 



Solieriaceae

 as Rhabdonia tenera). Noyack Bay; Tuthill Point on Moriches 

 Bay ; Patchogue, West Sayville and Bayshore on Great South Bay. 



Rhodophyllidaceae 

 Cystoclouinin piirpitrenm (Hudson) Batters, var. cirrhosum 

 Harvey. Buoy off Lake Montauk ; Lake Montauk ; Eastern Plain 

 Point on Gardiners Island ; Gardiners Point Islet outside Gardiners 

 Bay ; center of Gardiners Bay. The writer collected this variety at 

 Montauk Point 16 June 1936. It apparently has not previously 

 been reported from Long Island, though the species is known to 

 occur there.
