BREAKING OF THE MERES. 
A short notice under this heading occurrs in “ Grevillea,” Yol. 
ix., p. 5, to which the following notes are supplementary. The 
misapprehension under which the author laboured that the Echi- 
nella articulata of the English Botany had not been figured since, 
may, I think, be rectified' by a reference to “ Kutzing’s Tabulas 
Phycologiae,” where a figure of the same plant, undoubtedly, will 
be found under the name of Chcetophora puncti formis, and singu- 
larly enough the specimens from which the drawings were made 
came from Ellesmere, the same locality as that in which they were 
found by Mr. Phillips. Reference to Rabenhorst’s “Algae,” m ., 
3d6, will show that its existence was not ignored by this author, 
although both omit reference of any kind to either the name or 
the figure in English Botany. 
The principal motive of this communication is to furnish two 
or three extracts bearing upon this subject. The first of these is 
* I intend issuing a series of fasciculi of the New British species as 
soon as practicable ; 25 species for £1 Is. Those marked with an asterisk 
will appear in the 1st fasciculus. Only 25 sets will be prepared.
