nearly all of which I have. personally gathered and identified. I know of 
only two papers, other than my own in Proc. Linn. Soc. N.S.W., where 
records of freshwater Alex in New South Wales may be found. (1) Raci- 
borski, Desmidya zebrane przez Dr. EH. Ciastonia, 1892, where about 70 
species of Desmids are noted from the Centennial Park, Sydney. (2) Nord- 
stedt, Frw. Alew of N. Z. and Australia, 1888, in which the Blue Mountains 
are given as the habitat of a dozen species of freshwater Algw, mostly 
desmids. In the following list the former are distinguished by an * asterisk, 
the latter by a 7 dagger. 
Yor the references I desire to acknowledge my indebtedness to Nordstedt, 
Index Desmidiacearum; to W. and G. S$. “West, Monograph of the British 
Desmidiacex; to De Toni, Sylloge Algarum; to P. 'T. Cleve, Synopsis of the 
Navyiculoid Diatoms; to Van Heurck, Treatise on the Diatomacee; and to 
V. B. Wittrock and N. Wille whose papers on freshwater Alge are a mine of 
information on very early references.
