(By E. S. Gepp.) 



Fresh-water Algae of the Azores.* — K. Bohlin has made a study 

 of the fresh-water algge of these islands, but he does not pretend that 

 this is in any way complete, as his collections were made during one dry 

 season, June to August, only, and were for the most part confined to 

 one island. The number of species now known from the Azores is 171, 

 of which 158 were found by the author, 134 of these being new to the 

 islands. One new species and one new variety are described, and a 

 new genus, Chlorohotrys, is formed for the reception of Chlorococcwn 

 regularis West. The author treats his subject under the following 

 headings : General sketch of the nature of the Azores ; the lacustrine 

 algae ; the algae of the marshes and streams ; aerial algae ; the algae of 

 the hot springs ; general character and origin of the algal flora ; 

 systematic list of the fresh-water algae of the Azores ; list of localities ; 

 bibliography. 



Fresh-water Algae of South Patagonia.f — 0. Borge has made 

 collections of fresh-water algae at various localities in South Patagonia, 

 between Punta Arenas on the north coast of the Magellan Straits, and 

 Santa de los Baguales, about 50° 10' S. lat. and 72° 5' W. long. He 

 records about 150 species, and states that the small number of species is 

 probably due to the saline character of the soil. Certain genera, such as 

 Arthrodesmus, Micrasterias, Penium, Tetmemorus, and Xanthidium, are 

 not represented at all, while Euastrum has only three, and Pleuro- 

 tcmium only one species. Six new species and several new varieties are 

 described.
