576 SUMMARY OF CURRENT RESEARCHES RELATING TO 



present part contains the treatment of the Phaeophyceaa, Chlorophyceaj, 

 and Cyanophyceae. Interesting observations are made on Haplospora 

 Vidovichii Born., Ectocarpus confervoides Le Jol., Giffordia Lebelii Batt., 

 and Myrionema punctiforme Harv. 



V. Spinelli * has made a study of the marine algae of Sicily, from which 

 island he records 160 species. Special observations are made on the 

 following : Schizymenia Dubyi J. Ag., Halymenia ligulata J. Ag., Cally- 

 menia demissa J. Ag., Nitopliyllum uncinatum J. Ag., and Codium 

 elongatum Ag. 



Marine Algae from New South Wales.t — A. and E. S. Gepp pub- 

 lish notes on a small collection of marine algae made by Mr. A. H. S. 

 Lucas mainly in the neighbourhood of Sydney. The novelties described 

 are : Dktyota prolificans, GracUaria Lucasii, new varieties of Rhabdonia 

 robusta and Grateloupia filicina, and a new form of Pterocladia lucida. 

 The cystocarps of Kallymenia tasmanica and Grateloupia austral is have 

 been found for the first time in this collection, and the latter species is 

 alfeo here described, having been till now merely a nomen nudum. The 

 characters of the fertile frond of Dictyota nigricans are figured to show 

 the difference between this species and D. prolificans ; no figure of the 

 former species had hitherto been published. GracUaria Textorii is here 

 recorded from New South Wales, being the only locality in which it has 

 been found outside Japan. Mr. Lucas's notes on each species are added 

 to the critical notes of the authors. 



Norfolk Island Algae.* — A. H. S. Lucas gives a list of ten marine 

 algae in J. H. Maiden's account of the flora of Norfolk Island. They 

 were collected by Robinson, Maiden, and Boorman in November 1902. 

 No algae, save Plocamium hamatum, appear to have been previously 

 recorded for the island. 



Japanese Algae. § — J. Matsumura publishes an index of Japanese 

 plants, with the species arranged alphabetically under their classes and 

 sub-classes. The habitat, Japanese name, citations of literature, 

 synonyms, and a bibliography are added. The algae attain a total of 

 1357 species, including 21 Schizophyceae, 557 Diatomacea?, 134 Con- 

 jugates, 115 Chlorophyceae, 17 Characere, 174 Phaeophyceas, and 339 

 Rhodophyceae. 



Yorkshire Fresh-water Algae. || — W. Ingham gives a list of twenty- 

 one of the more interesting fresh-water algae recorded for the York 

 district. Most of these come from Pilmoor, where so many as 130 

 species of Desmids have been found. 



Fresh-water Algae from Finland.^" — A. J. Silfvenius publishes 

 some notes on the distribution of Chlorophycese and Cyanophycese in 

 Finland. He enumerates 111 species, of which 92 are Chlorophycese
