hypnseoides, Gladophora rugulosa, and Microdictyon pseudoha/pteron. 



The second of the two parts includes figures of a new species, Botryocarpa 

 japonica Okam., as well as of Delesseria fimbriata De la Pyl., I). Midden-

Marine Algae from the Kermadecs.* — A. and E. S. Gepp publish 

 a short list of marine algae from the Kermadec Islands, collected by 

 R. B. Oliver in 190H. The list includes thirty-seven species and repre- 

 sents the first published record of algae from the islands. None of the 

 species are described as new, though possibly one may prove to be so, 

 when more is known of the genus to which it belongs, Oalaxaura. A 

 new combination is made, Gystophora etongata Dickie being placed in 

 Carpophyllum, with a short explanatory note. G. elongatum was not 

 among the collection from Oliver, but it had been previously recorded 

 from the ocean thirty miles off the Kermadecs by the ' Challenger ' 

 Expedition. In some short introductory remarks, rmotations are made 

 from Oliver's own report on the Vegetation of the Kermadecs. t 



Algae of the Sheffield District.} — M. H. Stiles gives a list of the 

 Algae and Diatornaceae of that portion of the West Riding of York- 

 shire which extends from Sheffield to Thorne, with Doncaster as the 

 natural centre. The list comprises about 100 species, and is followed by 

 short notes on various localities in the district. 



Algae and their Study. § — This is the title of a popular lecture 

 given by F. L. M'Keever in Edinburgh, in which a short sketch is given 

 of the general outlines of classification of algae, followed by a list of 

 forty-one fresh-water species found by the author in Midlothian. The 

 most interesting of these is Desmonema Wrangelli B. & F., which is 

 described by West as being one of the rarest blue-green algae in the 

 European flora. 



Algae of the Elf Loch.|]— F. L. M'Keever enumerates seven new 

 records of algae from the Elf Loch, the flora of which had been already 

 published. 



African Fresh-water Algae. If — E. Lemmermann gives a list of the 

 fresh-water algae collected during the German Expedition to Central 

 Africa in 1907-8. The collection includes eighty-one species, of which 

 two are new, Phormidium africanum, and Peridinium bidens, as well as 

 two new varieties of known species. The localities were Mohasi Lake, 

 Ruanda, Kiwu Lake, and Rugege forest.
