were sent to him by other botanists. All sides of the island are repre- 

 sented, and the locality of each species follows the record of its occur- 

 rence. The present paper includes fifty-seven algas, belonging to 

 Florideas. Many of the notes deal with questions of nomenclature. 



Arctic Algae.* — J. Palibin reports on the botany of the south-east 

 portion of the northern island of Nova Zembla, and gives a short list 

 of marine algae, all of them characteristic of the Arctic region. The 

 collection was made during the Expedition of the Ermak, during the 

 summer of the year 1901. A few fresh-water species were found above 

 Cape Flora on Franz Josef Land. The report is in Russian. 

 F. R. Kjellmanf gives a list of 22 alga? from the coasts of this 

 island, among which are several new records for the locality, including 

 Halosaccion pubesems, hitherto only known on the Norwegian coasts. 



Marine Algae from the Red Sea.| — Th. Reinbold publishes a list 

 of 82 species, collected at Tor on the Sinai Peninsula, of which four 

 species have not hitherto been recorded from the Red Sea. In the 

 case of the more interesting specimens, critical notes are added. The 

 material was collected on coral reefs at a depth of about 1-3 metres. 



Indian Ocean Algae. § — E. S. Barton publishes a list of 27 species 

 of marine algas from the Maldive and Laccadive islands. They were 

 collected by J. Stanley Gardiner, and form the first published record 

 from these islands. Among the species is Ralfsia ceyJanica Harv., till 

 now a nomen nudum, though authentic specimens exist in herbaria. 

 Ectocarpus spongiosum Dickie is recorded in fruit, and the original 

 description of the plant is here supplemented by an account of the 

 plurilocular sporangia. It is interesting to note that the fruits occur 

 on the original specimens of E. spongiosus in the British Museum and 

 Kew herbaria, but they were overlooked by the author. A new species, 

 Liebmannia Laccaclivarum, is described. 



Marine Algae from the Gulf of Manaar.|| — E. S. Barton also gives 

 a list of 25 species collected in this region by Herdman when ex- 

 amining the Pearl Oyster Fisheries in 1902. The most interesting 

 record is that of Halimeda gracilis in fruit, which has not been 

 described up to the present. Sporangia are borne in a kind of loose 

 raceme on sporangiophores, and these arise from the filaments of the 

 central strand which have branched to form lateral strands. The tufts 

 of sporangiophores are limited to those points of the margin of a joint 

 at which the lateral strands issue, and in this manner differ from the 

 fruits of H. Tuna, in which the sporangiophores are said to form a 

 fringe round the upper margin of a joint. 



Three New Japanese Algae. f — K. Yendo describes a new Caulerpa, 

 C. Tateyamensis, which resembles C. sedoides, but is distinguished from 

 it by the stipitated cylindrical ramules and the character of the branch-
