the plant distributed as W. X. & L., No. 1586. The Cliff Pool plants 

 have mostly more distant ramuli, but some indi\'iduals are quite 

 typical. At Hungry Bay a form was found in which the ramuli were 

 produced on one side of the frond only; not secund in the usual sense, 

 as they were not in a single series, but were placed, apparently irregu- 

 larly, on one semi-cylinder of the axis, the other being naked.

 were visible, often only the tips.

 and as we have not ourselves foimd this species, we do not include 

 it in the present work.
