412 [October, 



Ectocarpus littoralis, Lyngb. Very abundant in the Bays, on various sub- 

 merged substances. Also fringing the steep banks of the thoroughfares be- 

 tween tide marks. Disappearing in July. 



Ectocarpus siliculosus, Lyngb. Occurs sparingly on the shores of Little 

 Bay, on Fucas vesiculosus. 



Ectocarpus viridis, Harv. Common in the Bays, on Zostera marina, &c. Dis- 

 appearing in July. 



Series II. RHODOSPERME^E. 

 Chondria dasyphylla, Ag. Plentiful in Little Bay, and on " Bond's Bar/' 

 growing in large tufts on the sandy mud, to which it is attached by a fibrous 

 root. 



Chondria Baileyana, Mont. Common with the above. 



Polysiphonia Olneyi, Harv. Rare, on Zostera marina in "Little Bay." 



Polysiphonia Harveyi, Bailey. Very abundant in the Bays, and on Bond's 

 Bar ; on Zostera marina. 



Polysiphonia variegata, Ag. Very common, on Zostera marina, also at- 

 tached to the mud by a fibrous root. 



Polysiphonia nigrescens, Grev. I collected fine specimens of this most va- 

 riable plant, in fruit, in the month of May. It occurs in great abundance in Lit- 

 tle Bay, attached to the bottom by a fibrous root. 



Champia parvula, Harv. Plentiful in Little Bay, on Zostera marina. < 

 Grinnellia Americana, Harv. Of this beautiful plant I only found a soli- 

 tary perfect specimen. It was growing in the Great Egg-Harbor Bay near the 

 shore, attached to the bottom by a somewhat fibrous root. The frond consists 

 of a leaf-like expansion, four inches long, and two inches wide. Several leaf- 

 lets, in as many stages of development, spring from the base of the midrib, 

 giving evidence of vitality. 



I had previously discovered fragments of this interesting plant, cast ashore 

 near the inlet, and also in the Great Egg-Harbor Bay, one of which I sent to 

 Professor Bailey of West Point, who suggested that it was a drift specimen, 

 probably from the narrows of New York Bay, where it occurs abundantly. 

 Notwithstanding that these fragments may have been stragglers, I have had suf- 

 ficient evidence that this species is an inhabitant of Beesley's Point, and there- 

 fore give it a place in my catalogue. 



Gracilaria multipartita, J. Ag. Plentiful, particularly fine on planted 

 oysters in Little Bay. 



Solieria chordalis, J. Ag. Very common on all the shores. There can be 

 no doubt, but this bushy plant will grow and flourish in the coves of Little 

 Bay, and other sheltered situations, without a foothold, for I have rarely found 

 it attached to the bottom. 



Chylocladia Baileyana, Harv. Frequent on Zostera marina, Ulva latissima, &c 



Spyridia filamentosa, Hnrv. Particularly abundant and vigorous in the 

 Bays ; where, sheltered from the winds and waves, like the Solieria chordalis, it 

 will luxuriate without the slightest attachment to the bottom. 



Ceramium rubrum, Ag. This plant, in all its perplexing varieties, is found on 

 Zostera marina, rather abundantly. 



Ceramium diaphanum, Roth. Occurs sparingly associated with the above. 



Ceramium fastigiatum, Harv. In dense tufts, on Zostera marina, rather rare. 



Callithamnion byssoideum, Am. Frequent on Zostera marina, also attached 

 to old shells in Great Egg-Harbor Bay. 



Callithamnion polyspermum, Ag. Rare, on old shells in Great Egg-Harbor 

 Bay. 



Gklidium corneum, var. y. pinnatum, Grev. I obtained two or three speci- 

 mens of this plant in Little Bay, on old shells, near low-water mark.
