BULLOCK-WEBSTER, G. R., Characeae from County Monag- 

 han. (The Irish Naturalist. Dublin. XI. June 1902. p. 141 

 — 146.) 



The author records the results of his researches among 

 the numerous pools and lakes of Co. Monaghan in August 

 1901. His best discoveries were Nltella mucronata Kuetz. in 

 abundance near Carrickmacross and N. flexllis var. nidifica 

 Wallm. in Co. Cavan, both new to Ireland. He adds a note on 

 the similarity of the peat and shell-marl here and in the fens 

 of Cambridgeshire, and quotes a theory that this shell-marl 

 may be due largely to the decay of Characeae.
