a large amount of material from the Florida-West [ndia region, 

 including specimens determined by J. G. Agardh, and can find no 

 line of demarcatioii between the three species mentioned. Fueui 

 Lamourouz, 1 S <»:>. PI. XXX, figs, 2 3, antedates F, Wrightii, 

 but now proves to U- a Laureneia, and the next oldest name is Turner's 

 which we adopt It includes most of the coarse, fleshy or cartilagi- 

 nous Gracilarias of the wanner Atlantic; probably always terete when 

 alive, l>nt often appearing compressed in herbarium material. It is 

 not common at Bermuda.

77. p. .Ms. Mrs. Boggs, 1895; St David's Island, Feb., May, Smith 

 Shore. April, Hervey; tetraspores in May. This species varies con- 

 siderably in color and texture, from thin membranaceous and clear 

 red to subcartilaginous and brownish. In the former case the shape 

 and subdivision of the frond are indicated by the specific- mime; 

 in the latter the division is more irregular. The Bermuda plant 

 rule has a thinner frond and narrower segments than the Florida 

 material distributed as P. B.-A., No. 334. We were at first inclined 

 to identity this plant with G. Textorii (Suringar) Ilariot, 1891, p. 223, 

 Sphaerococciu Textorii Suringar, 1870, p. 36, PI. XXIII. and a sp 

 men from Province Boshu, Japan, for which we are indebted to the 

 kindness of Dr. I\. Yendo, has much resemblance to the Bermuda 

 plant But the plant figured by Okamura, 1901, p. 65, PI. XXIII, 

 and distributed in his Algae Japonicae Exsiccatae No. 13, differs 

 considerably, having a habit more like the common little divided forms 

 of Rhodymenia palmata. Our plant agrees with Crouan's sp< 

 as represented by an authentic specimen in the Museum d'Histoire 

 Naturelle, at Paris, and it has seemed to us better on the whole to 

 retain for the present Crouan'a name, under which the plant had 

 already been distributed in B. B.-A. J. G. Agardh, L889, p. 25, refers 

 to G. dichotomo-flabellata as a possible Bynonym of Chrysymenia haly- 

 menioides Harvey, mentioning Chrysymenia dichotomo-flabellata ( 'rouan 

 as perhaps the same; the latter has been distributed as B. B.-A.. No. 

 it i> probable that it is, as suggested by J. ('• Agardh, a form of 

 Chrysymenia halymenioides, hut the plant distributed ;i- P. B.-A., 

 Nbs. 334 & L931 i- certainly a Gracilaria. The following short diag- 

 nosis, in connection with the material distributed as P. B.-A.. Nos. '■>'■'< I. 

 L931, will probably give a sufficient idea of the species.
