678 SUMMARY OF CURRENT RESEARCHES RELATING TO 



families of that order. The first, Chroococcaceae, is shortly defined, and 

 then follows a key to the fifteen genera it contains. Diagnoses are given 

 of the first few species of Chroococcus. 



Algae of Alderney.* — E. D. Marqnand publishes additions to the 

 flora of this island, in the first of which he gives a list of 62 marine 

 algae, and in the second a list of 14 marine and 63 fresh-water species, 

 as well as 9 Desrnidiaceae. Each species-name is followed by the name 

 of the locality where it occurs. 



New Algae from Java and the Philippines.f — W. Schmidle de- 

 scribes four new species, one of which is the type of a new genus, Myxo- 

 balctron. They are Pliormidium Usterii, Lyngbya Usterii, Pleurocapsa 

 Usteriana and MyxobaMron Usterianum. They are all named after the 

 collector. 



Marine Algae of the Caroline Islands, etc.J— K. Okamura publishes 

 an interesting list of algae collected in the Caroline Islands, Australia, 

 Tasmania and New Zealand. He enumerates 16 Chlorophycese, 

 25 Phaeophyceae, 40 Florideae, and 2 Schizophyceae. Among the algae 

 are specimens of Cystoseira articulate Kiitz., and the author adds an 

 interesting and instructive note on its structure, synonymy and allies. 

 He doubts whether Hormopliysa articulata Kiitz. is really a synonym of 

 Cystoseira laUfroiis Kiitz., as De Toni suggests in his Sylloge Algarum. 

 He puts forward the question whether Hormopliysa articulata is distinct 

 from Hormosira (?) articulata Zan., and whether the latter is the same 

 as Cystoseira prolifera J. Ag., or C. triquetra J. Ag. He also describes 

 the anatomical differences between C. articulata and Hormosira Bariksii. 

 Figures of portions of C. articulata add to the interest of his remarks. 

 Separate short lists of the species collected at each locality complete the 

 paper. 



American Algae.§ — F. S. Collins publishes a note on a small 

 collection made by a sailor with no special knowledge of Algae. The 

 localities range from Newfoundland and Bay Chaleur to Yucatan. The 

 only fresh-water algae are specimens of Stigeoclonium and Ulothrix which 

 were found on pine logs coming down the river to some port in Florida. 

 Among the marine species are several which enlarge the geographical 

 distribution hitherto recorded. The most interesting plants, however, 

 are luxuriant specimens of Caulerpa prolifera Lam., Codium tomentosum, 

 Stackh., Bryotliamnion Seaforthii Kiitz., and Eucheuma isiforme J. Ag., 

 from Progreso, Mexico. Hitherto it has been supposed that the coast 

 of Mexico was barren, but the presence of these algae indicates that this 

 theory is not well-founded. 



Two Algae from the Malay Archipelago. || — A. Weber van Bosse 

 makes some interesting observations on two algae in her collection made 

 on the Siboga Expedition to the Dutch East Indies. One is a new 

 species, forming the type of a new genus, Tapeinodasya Borneti. The
