British Marine Algse.* — B. A. L. Batters publishes some inter- 

 esting notes on eleven new or critical species of British marine algse, of 

 which two are new to science, and at least three are representatives of 

 genera never before found in Britain. The novelties are Diplocolon 

 Godii, which is epiphytic between the cortical cells of Codium tomentosum ; 

 and Mesogloia neglecta, which greatly resembles M. Griffithsiana, but is 

 distinguished by the very much shorter cortical filaments and the pro- 

 portionally large spores. The other species treated of are : Ghlorogloea 

 tuberculosa Wille, Ghcetobolus gibbus Rosenv., Ulothrix consociata Wille, 

 Leptonema lucifugum Kuck., Leathesia crispa Harv., here first recorded 

 from Ireland ; Dictyota spiralis Mont., Acrochwtium Alarm, Rhodo- 

 chorton penicilliforme Bosenv., and Rhododermis elegans Cronan var.
