lected in 1902-4 at the South Orkneys, and in the warmer waters off 

 the coast of Brazil, at St. Paul Rocks and the Cape Verde Islands. The 

 number of species enumerated is 29, and 15 of these came from the 

 South Orkneys, an Antarctic group. The structure of the new species 

 is described and figured. 



E. M. Holmes * reports on the calcareous algas collected by the 

 aforesaid expedition at the South Orkneys, and on the fragmentary algge 

 attached to them, 10 species in all, -4 of which are Corallines. 



M. Foslie t describes two new forms of calcareous alga3 which occur 

 abundantly at the South Orkneys. The death of the author in 1909 

 prevented the expected amplification of the descriptive notes. 



Marine Algas from Little Barrier Island and the Kermadecs.| — 

 A. I). Cotton describes two small but interesting collections made at 

 these two localities by E. M. Smith. Four new genera are added 

 to the New Zealand region and a new species of HaJiseris is described 

 from the Kermadecs. This resembles in habit H. poiypodioides, l)ut 

 differs from it in structure, being closely allied to the West Indian 

 H. pJagiogramma. 



Marine Algas of N.W. America. § — W. A. Setchell begins a series 

 of papers on new or little known algte. In the present contribution 

 thirteen species and one form are described, most of them being novelties 

 from the Pacific coast of Xorth America. There are two new genera, 

 Hapterophijcus and Besa, belonging respectively to Ralfsiacea3 and Gigar- 

 tinaceaj. For the name of the latter genus the author has gone to Egypt, 

 the god Bes (Greek Bijo-a) being "always represented as a dwarf and 

 extremely small even at that." One of the species described, Dudresnaya 

 australis J. Ag. sp. ined., is represented by " four magnificent specimens " 

 in the British jMuseuin, which were collected by J. Bracebridge Wilson 

 in Victoria, Australia, 



Oceanic Algology.|l — A. Mazza continues and completes his account 

 of the genus Geramium, giving descriptions of the structure and charac- 

 teristics of seven more species of that genus. 



Crouan Collections of Algae.f— C. A. Picquenard has been making a 

 revision of the collections of the brothers Crouan, and publishes additional 

 localities for some of the species of FucoideEe. He also makes critical 

 notes on a species of Ohara and seven species of Nit ell a. The collections 

 include gatherings of many other algologists, including Chauvin, Lenor- 

 mand, Areschoug, Suhr, Bory, and others.
