stinguishable from V. imhricata, with which it was at first con- 

 founded by me, first, by the more delicate texture of the whole 

 polypidom ; secondly, by the smaller size and oval shape of the 

 cells. In Valkeria imbricata the cells are cylindrical ; the clusters 

 of cells in it, too, are more nearly approximated, and the number of 

 cells in each cluster is more numerous than in V. cuscuta. 

 Abundant, Sandy-cove, near Dublin.
