anticlinal moniliform rows of colored cells, enclosing pear-shaped or 

 elliptical utricles at 1-2 heights, the inner 35-50/i, thick, of loosely 

 interwoven corticating filaments ; monoecious ; antheridia nearly or 

 entirely covering the surface, consisting of slender branches abjointing 

 solitary (?) oblong antherozoids ; cystocarps pyriform, 105-120(U, (R) 

 (160-180/x with neck) by 120-135;Lt (T) with a periderm of 6-7 layers 

 of interwoven coarse filaments, opening gradually outward by a long 

 carpostome. 



Gloiophloea Okamurai is founded on a specimen distributed by 

 Okamura under No. 2 of his Algae Japonicae Exsiecatae and labelled as 

 Scinaia furcellata. This is not the same, however, as the Scinia furcel- 

 lata of his Icones of Japanese Algae (vol. 1, no. 1, p. 10, pi. 2, fig. 19, and 

 pi. 3, figs. 16-20, 1907) which is a true Scinaia and is referred above 

 to Scinaia japonica. While this statement refers to No. 2 of the copy 

 of Okamura 's Algae Japonicae Exsiecatae in my own possession so far 

 as the type specimen is concerned, I have found that identical speci- 

 mens are to be found also in three diiferent sets of the same exsiecatae 

 in Herb. Farlow. These specimens were all credited to Enoshima, 

 Japan, whence also there is a specimen of Gloiophloea Okamurai, 

 collected by H. M. Richards. H. ]\I. Richards also collected the same 

 species at Kamakura, Japan, according to a specimen in Herb. Farlow. 

 I have been able therefore to examine some six specimens of this 

 proposed new species and find them to agree in all essential characters. 



Gloiophloea Okamurai is a monoecious species and may be dis- 

 tinguished from Gloiophloea Scinaioides by its darker red color, less 

 f astigiate branching, less number of dichotomies, and its thinner cortex ; 

 from G. undulaia, of the same group, it is to be distinguished chiefly 

 by its thinner cortex; while from G. HaUiae of Florida it is to be 

 separated by its somewhat thicker cortex.

Plate 10, fig. 13. 



Plant 11-13 cm. high, 5-7 times dichotomous, cylindrical, contin- 

 uous, 2 mm. broad (dried), deep wine red; cystocarps scattered; 

 — axis slender ; adult outer cortex 22-40/x, thick of anticlinal corymbose 

 colored filaments with ovate utricles at two heights ; corticating layer 

 20-45/x thick, very lax; monoecious ( !) ; antheridia thickly covering the 

 surface, fasciculate; cystocarps globular pyriform lOO-llS/x (T) by 

 66-88/A (R, without the broad carpostome) ; periderm filamentovTS, 

 thick, of 5-6 layers.
