 —XXX. Tokyo 1902. 



The species here figured and described in English and 

 Japanese are Lomentaria catenata Harv., Phacelocarpus japonicus 

 nov. sp., Cutlerla cylindrica nov. sp., Cladopora Wrightlana 

 Harv. and Rhipidiphyllon reticulatum (Ask.) Heydr. 



Both cystocarps and tetrasporangia of Lomentaria articulata 

 are here described and the author is able to remove the plant 

 from its uncertain position in the genus and shew that it is a 

 distinct species, related to L. articulata Lyngb. In Phacelo- 

 carpus japonicus, both cystocarps and tetrasporangia are 

 axiliary and pedicillate and the author places it in the subgenus 

 Euctenodus, near P. Labillardieri. Comparisons are drawn 

 between it and the other species of the genus. Cutlerla 

 cylindrica somewhat resembles Stilophora Lyngbyei in appea- 

 rance; in structure it differs from the other species of Cutlerla 

 in having a radial, instead of a bilateral, symmetry. Under 

 Rhipidiphyllon reticulatum, the author discusses the advisability 

 of uniting Rhipidiphyllon and Microdictyon, since the difference 

 between the genera is slight, being confined to the shape of 

 the cells of the veins and to the habit.

SCOTT, RlNA, How to keep a salt- water aquarium for 

 algological experiments. (The New Phytologist. Vol. I. 

 1902. No. 6. p. 124—126.) 



Instructions as to the management of a salt-water aquarium, based 

 on the experience of many years. The salinity of the water is tested by 

 means of specific gravity balls and regulated accordingly, this avoiding 

 the necessity of changing the water. A few periwinkles are allowed to 

 live in the aquarium, in order to keep down a superabundance of green 

 spores. Germination of spores of certain Florkleae has been successfully 

 watched, by allowing such spores to collect on small V 2 mcn Squares of 

 mica, suspended among branches of the fruiting alga. E. S. Barton.
