it includes Floridese, Chlorophycese and Phycochromophycese, 

 while the Diatomese have not yet been identified. The author 

 calls attention to the fact that no species was observed of the 

 genus Cladophora, although CI. gossypina Kiitz is reported from 

 Adelaide, and CI. IVot/sn Sond. from the Parramatta River. It is 

 also strange that the Characese were entirely absent, since this 

 family is very well represented in New Zealand according to 

 Nordstedt. =^'- 



Four species are described and figured as new to science: 

 Coleochcete Baileyi, C. conchata, Stigeocloniiuii aiistralense and 

 Scytonema subtile., besides a number of new varieties. The paper 

 contains many critical notes and gives the geographical distri- 

 bution of all the species in question. 



F. Heydrich: Algce from New-Guinea. -\ 



A large collection of salt-water Algse from New-Guinea, 

 made by Capt. Schneider in the year 1891, has been identified by 

 the author, who enumerates the species in the present paper. 

 Several species of Cyanophycese, Chlorophycese, Phaeophyceae 

 and Florideae are enumerated, and additional notes are given as 

 to the literature and the geographical distribution of the species. 

 The following are described and illustrated as new to science: 

 Osdllajia microscopica , Ectocarpus clachistccformis, Strcblonema 

 nmiutula, Zonaria parvula Grev. var. duplex and Bostrychia 

 crassula. 



G. DE Lager heim: Trichophilus Nenia\\ 



It is a fact of great interest, that certain Algae live exclusively 

 upon live animals. Some of these are true parasites and very 

 injurious to their hosts, while some other ones are merely 

 epizoic. To the last category belong for instance: Cladophota 

 ophiflphila, which grows upon Herpeton, Characium upon 

 Entomostraca, Cyanoderma upon Bradypus, etc. The author 

 has, however, discovered a species of Tricophilus growing
