Diatoms of Upper Austria.*— R. Bandmann has examined with 

 special regard to diatoms, the following waters. Some pools near 

 Windegg and St. Peter in the district of Zizlau by Linz, an arm of the 

 Danube in the water-meadows near Steyregg, rocks on the edge of 

 the Danube near Aschach and Margarethen, Linz. The localities were 

 often visited. From the tabular synopsis of the algse of the Danube 

 area round Linz it may be gathered that the author records eight 

 times as many species as Schiedermayr. They belong to 35 genera. 

 Only five of Schiedermayr's species were not found by the author. 

 Five of the species, determined by Peragallo, are identical with those 

 found by Heribaud or Peragallo in tertiary strata in Auvergne. These 

 species are described in detail, since they are varieties. In all, 108 

 species recorded by Handmann from the Danube region have been 

 found fossil in various strata in Auvergne. 





Diatoms of New Brunswick and Prince Edward Island.f — L. \Y. 

 Bailey refers to the scarcity of literature on Canadian diatoms, gives 

 a sketch of the physical conditions that characterize the region in 

 which his own collections were made, and presents in a classified list 

 the forms which so far have been observed. He adds critical notes on 

 the more important genera, and draws some general conclusions from 

 the facts recorded, concerning : (1) the remarkable richness of the 

 diatom flora about the New Brunswick coasts ; (2) the remarkable 

 commingling of fresh-water and salt-water species (owing to the great 

 fluctuation of tides in the Bay of Fundy) ; (3) the character of the 

 plankton ; (4) the relations of the Diatoms to each other and to other 

 forms of life ; (5) contrasts between the Diatom flora of the Bay of 

 Fundy and Gulf of St. Lawrence ; (6) geographical distribution ; 

 (7) generic and specific distinctions. He is of opinion that far too 

 many species have been founded upon trifling distinctions of length and 

 striation. Coscinodiscus Bailey ana Mackay is a new species. 



Norwegian Protococcoideae.J — H. Printz publishes his investigations 

 of the Protococcoidea3 in the neighbourhood of Christiania. After a 

 short account of the literature on the Norwegian species and the group, 

 he gives a list of all the hitherto known species. He himself has added 

 largely to the number by his collections in the region round Christiania, 

 representing different geological formations. He shows the difference 

 caused by the presence or absence of lime, and other constituents in 

 the soil. The principal part of the work is devoted to the systematic 

 treatment. Two new genera Dispora and Bumilleriopsis are defined, 

 many new species and varieties are described and figured ; and to very 

 many records important critical notes are appended, which add largely 

 to the value of the work.
