308 Recent Literature. [ZOE 
it includes Florideze, Chlorophycezee and Phycochromophycez, 
while the Diatomez have not yet been identified. The author 
calls attention to the fact that no species was observed of the 
genus Cladophora, although C/. gossypina Kiitz is reported from 
Adelaide, and C/. MWollsii Sond. from the Parramatta River. It is 
also strange that the Characeze 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: 
Coleochete Baitleyi, C. conchata, Stigeoclonium australense 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. Hrypricu: Alge from New-Guinea.t 
A large collection of salt-water Algz 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 Cyanophycez, Chlorophycez,. Phaeophyceze 
and Florideze 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: 
Oscillaria microscopica, Ectocarpus elachisteformis, Streblonema 
minutula, Zonaria parvula Grev. var. duplex and Bostrychia 
crassula,

It is a fact of great interest, that certain Algze 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: Cladophora 
ophiophila, which grows upon Herpeton, Characium upon 
Entomostraca, Cyanoderma upon Bradypus, etc. The author 
has, however, discovered a species of Tricophilus growing
