280 SUMMARY OF CUEBENT RESEARCHES RELATING TO 



Japanese Seaweed, Tosaka Nori. — A. D. Cotton {Keiv Bull, 

 1914, No. 6, 219-22). An account of the history of Eucheuma papulosa 

 (Mont.) Cotton and Yendo, with synonomy, description and biology. 

 Its identity with the edible alga of Japan had not hitherto been 

 recognized. The authors transfer it from Gallymenia to Eucheuma.

Notes on Australian Marine Algae. II. — A. H. S. Lucas {Proc. 

 Linneaii Soc. Neiv South Wales, 1919, 44, 174-9, 1 pi.). Descriptions 

 of four new species : — (1) Lanrencia infestans, a dwarf species occurring 

 in large patches on EcMonia radiata var. exasperata. (2) Falkenbergia 

 olens, which was washed in by the sea and smothered the oyster-beds, 

 causing great damage to the industry, killing the oysters, and causing a 

 vile stench. The plague occurs at irregular intervals. (3) Polysiphonia 

 zostericola, abundant on Zostera leaves in Sydney Harbour. (4) Tricho- 

 desmium scoboideum, collected at Hope Islands, near Cooktown, in June, 

 1918, by A. E,. McCulloch ; it covered the sea, and looked like brown 

 sawdust, being regarded locally as a sign of good weather. It is an 

 important food item to a large number of reef animals. A. G. 



Sub-Antarctic and Antarctic Marine Algse. II. : Rhodophycese. — 

 H. Kylin and C. Skottsberg (Tf/'ss. Ergebn. Schwed. Sildpolar Exp., 

 1901-3, 1919, 4, 88 pp., 1 pi., 38 figs, in text). A critical account of 

 the Ehodophyceaj collected by Dr. Skottsberg on the Swedish Antarctic 

 Expedition, 1901-3. The working-out of the different families was 

 divided between himself and Dr. Kylin. New genera and species are 

 described and figured. Unfortunately the war prevented all comparison 

 with collections in herbaria outside Sweden, but the authors had access 

 to some of the algse collected in South Georgia by P. F. Reinsch (though 

 not determined by him), which happened temporarily to be in Sweden. 

 A synopsis of the geographical distribution of each species in the 

 Antarctic and Sub- Antarctic area is given in tabular form, and is followed 

 by an enumeration of the species in geographical groups, with remarks. 

 The notes appended to each record in this report, together with their 

 respective explanatory figures, form a valuable addition to Antarctic 

 algal literature. Five 'species of Cyanophyceae are recorded as being 

 found among the collection. E. S. G. 



Calcareous Algse from Murray Island, Australia, and Cocos- 

 Keeling Islands. — Marshall A. Howe {Carnegie Inst. Washington, 

 1918, No. 213, 291-96, 2 pis.). A record of seven species from Murray 

 Island and three from Cocos-Keeling. Of the former, one is the 

 cosmopolitan Halimeda Opuntia, and the rest belong to Corallinace^. 

 Heydrich's Lithothamnion Orthoblastum is transferred to the genus 

 Goniolithon, for reasons set forth in a discussion of its structural 

 characters. E. S. G.
