Genus, CHRYSYMENIA. J. Ag. 
Tubular, not constricted or jointed ; fructification, ceramidia containing a very 
dense tuft of angular spores ; also tri-parted tetraspores immersed in the ramuli. 
No. 78. C. divaricata. Filiform, branches involute, secund, ranged on one side 
only, tapering at base and apices ; pink to dark brown. 
Found only once after the July storm, floating at Fed Hook; very dense whorled tufts. 
Genus, CHYLOCLADIA. Grev. 
Constricted at regular intervals, and divided into chambers filled with a watery 
juice; fructification, conical ceramidia, containing a tuft of wedge shape spores ; also 
tripartite tetraspores immersed in the branches. 
No. 80. C. parvula. Ag. Sub-gelatinous, slender branched in a straggling 
sub-dichotomous manner, constrictions of equal length and breadth ; capsules ovate. 
In tide pools, Hurlgate, and Staten Island, summer, 2 to 8 inches long; somewhat anastomose, rare. 
Family IX. CORALLINES. Lamonr. 
Rigid, articulated or crustaceous, mostly calcareous, purple when recent, fading 
on exposure to milk white ; tetraspores tufted, contained in ovate or spherical con- 
ceptacles. 
Genus, CORALLTNA. L. 
Articulated, branched, coated with carbonate of lime, fructification, obovate ce¬ 
ramidia, pierced at the apex, mostly terminal, and containing a tuft of erect pyriform, 
or club shaped tetraspores. 
No. 83. C. officinalis. L. Irregularly branched, lower articulations twice as 
long as broad. 
Found at Hurlgate floating on other Algae; rare ; is very abundant in the Sound, a few miles from our 
harbor. 
Corallina must not be confounded with Coralline. The former is an Alga, and is classed with the ve¬ 
getables, while the latter is classed in the animal kingdom. Corallina officinalis, though coated with carbon¬ 
ate of lime, has beneath a structure resembling the Algae. We may have strong reasons for supposing, that 
all the Algae are animal, and might give facts to support such an. opinion ; but in the present treatise it is 
deemed best to leave them in the vegetable kingdom, where Linnaeus and other able Naturalists have placed 
them. The Corallines are, however, universally conceded to be animals. 
Family X. BELESSERIBiE. J. Ag. 
Rosy or purplish red, or blood red; leafy, rarely filiform, areolated, inarticulate, 
polygonal cells, membranaceous ; fructification, conceptacles external or half im¬ 
mersed, containing a tuft of dichotomous filaments ; also tetraspores in sori. 
Genus, DELESSERIA. Lamour. 
Rose red, flat, membranaceous, with a percurrent midrib ; fructification, hemi-
