ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 81 



Corallinaceae of the Pacific.*— M. Poslie gives an account of the 

 Corallinaceae collected by K. Recbinger during an expedition in 1905 to 

 the Samoa Isles, New Guinea Archipelago and Solomon Isles, including 

 two new species from the Sandwich Isles, one (Archaeo-lithothamnion 

 zonatosporum) from Los Angeles in California, and seven from Samoa. 



Studies in Marine Algae.t,— A. Mazza continues his studies of 

 oceanic algology and describes and discusses some species of the following 

 genera: Grinnellia, Caloglossa, Sarcomenia, Sonderella, Claudea, Van- 

 voorstia, Delisea, Bonnemaisonia, Asparagopsis. 



European Algae.J — W. Mignla continues the cryptogamic part of 

 Thome's Flora von Deutschland, Oesterreich und der Schweiz. Parts 

 57-65 treat of the Phasophyceas and Characeae, and complete the account 

 of the algaa. The descriptions are in German. Keys to the genera and 

 species are supplied. 



Antarctic Algse.§ — T. Reinbold gives an account of the marine 

 algae of the German South Polar Expedition (1901-8). He sketches 

 the work previously published on collections made in various parts of the 

 antarctic region, shows that our knowledge is still limited to a small part 

 only of that region, and that there is a well-marked sub-antarctic circum- 

 polar algal flora (characterised by Macrocystis and DurvilUm) distinct 

 from the proper antarctic flora (characterised by Desmarestia, Lesson ia 

 and Scytothalia). The stations from which specimens were obtained 

 were as follows : Kerguelen, Crozet Island, New Amsterdam Island, 

 Cape of Good Hope, St. Vincent (Cape Verde). 



• Marine Algse of San Thome. || — P. Hariot gives a list of thirty-eight 

 marine alga? from the Portuguese island of San Thome, off the coast of 

 West Africa, gathered by Quintas, Moller, Praenca, and Gravier. The 

 list contains twenty-one species which are additional to the flora of the 

 island, and raise its total to fifty-seven species or varieties. Gracilaria 

 Henriquesiana is a new species, and is figured. 



Red Sea Algae. 1 — R. J. Harvey-Gibson gives an enumeration of 

 the alga? collected in the Red Sea by C. Crossland, near Suakim, during 

 an investigation of the biology of the Sudanese marine fauna during 

 1904-5. Thirty-five species are recorded, being almost equally divided 

 between green, brown, and red algae.
