14 Algae. 



The Catalogue contains a systematical list of all the species ta- 

 bulated in the plankton lists oi' the „Bulletin" as observed within 

 the area investigated by the International Cooperation during the 

 named period. Under each species are given: 1) the sea areas from 

 where it was recorded, 2) the months and years of the records. 

 The Catalogue is therefore especially of biogeographical value. The 

 botanical part of the Catalogue (p. 1—58) has been worked up by 

 C. H. Ostenfeld; it contains the following groups: Chytridiaceae , 

 Myxophyceae, Chlovophyceae , Phaeocapsaceae , Flagellata, Peridiniales 

 and Bacülariaceae , about 350 species. C. H. Ostenfeld. 



Rendle, A. B. and others. The Nomenclature of Algae. 

 (Journ. of Bot. XL VII. 560. p. 309. 1909.) 



The botanists of the British Museum and others publish a 

 motion, which they have sent in for consideration at the Brüssels 

 Congress of 1910, wherein they suggest that the starting point for 

 the nomenclature of Algae should begin with the Systema Algarum 

 of C. A. Agardh. Their reasons are shortly stated. E. S. Gepp.

A short note on some specimens of this alga in the globular 

 form collected in Norfolk. The author states that he has seen 

 them in great abundance in the Broads and waterways of Norfolk; 

 indeed they may be so plentiful there in the spring, as to cause a 

 hindrance to the passage of wherries and other vessels. He also 

 remarks, that they possess great tenacity of life, as was proved by 

 a specimen which he kept in a jar for nearly nine 3^ears before it 

 began to decay. During that time it maintained a green and healthy 

 appearance, though it dit not perceptibly increase in size. The 

 views of Dr. Wesenberg-Lund are quoted with regard to their 

 formation and habit, and it is also stated that in some parts of the 

 country where the balls occur, the children use them for sponges, 

 to clean their slates. E. S. Gepp. 



West, G. S., Phytoplankton from the Albert Nyanza. 

 (Journ. of Bot. XLVII. 559. p. 244—246. pl. 498. July 1909.) 

 The plankton bere described was collected hy Mr. R. T. Leiper 

 and consisted of a sample of plankton, and a tube of material ob- 

 tained in thirty feet of water. Forty-eight species were observed in 

 the plankton collection, none of which could be described as domi- 

 nant. About two-thirds of these species also occurred in the col- 

 lection from near the bottom. A species of Microcystis and a large 

 diatom of the genus Vanheurckia are described as new. The per- 

 centage of species is as follows: Chlovophyceae 50°/ , Bacillarieae 

 29.1°/ n , Myxophyceae 12.5°/ n . Mention is made of specimens of Volvox 

 aureus Ehrenb», in which the number of daughter-colonies developed 

 within the mother-colony were fewer than is usually the case, and 

 they became ellipsoid or ovoid by compression before being set free.
