 John ]\Iaeoiin. Its distribution ah)ng the western coasts of North 

 America, then, extends from the southern boundary of the United 

 States (or below it in all probability) to Vancouver Island. 



Gloiophloea(?) articiilata AVebor van Bosse

Just at the time of writing there has been referred doubtfully to 

 genus GJoiophloea a species from the westerly portion of the Indian 

 Ocean. Through the kindness of Mme. Weber van Bosse I have been 

 able to examine a specimen of this plant. The habit resembles that of 

 the constricted species of Sciuaia Init the structure is not of that 

 group. Neither has it the structure of cortex or apical pit of Gloio- 

 phloea, at least as I understand it and have described it above. It 

 seems to me that the plant is likely to prove to be found to be a 

 member of the Chaetangiaceae, as Mme. Weber van Bosse has already 

 suggested. Init. in my own estimation, it is probable that it will also 

 be found to belong to an. as yet, midescribed generic type close to th(> 

 genus Chaetangium. At present it seems best to leave it under the 

 name assigned to it. but still farther emphasizing the doubt as to its 

 generic designation. 



PSEUDOSCINAIA gen. nov. 



Frond arising from a disk, cylindrical, continuous, repeatedly 

 diehotomous. with blunt apices and branches of the same diameter 

 throughout, devoid of calcification; — axial strand of nearly j)arallel 

 thin walled broad filaments more or less firmly agglutinated together, 

 whence slender branchlets are obliquely upwardly excurrent, whose 

 terminal portions are comljined into a continuous cortex whose inner 

 layers are colored but whose outer layers, or "e])idermis." is made up 

 largely of inflated colorless cells, or utricles, between which slender 

 colored cells are more or less regularly scattered, the whole being clothed 

 externally by a distinct cuticula ; slt^ich^r corticating filaments may 

 accompany the axial .strand and clothe the inner surface of the cortex; 

 the space between the axial strand and the inner surface of the cortex 

 is filled with a dilute jelly; tetrasporangia unknown; antheridia single 

 or few together; insei'ted between the utricles; cystocarps scattered, 

 originating within the cortex and partially or nearly entirely sus- 

 pended in the interior jelly, more or less globular to pyriform, with
