SMALL POOLS, HONEYSUCKLE FLAT. 
These were a series of small **saucer-holes" only а few feet across and 
very shallow. The water becomes warmed up almost to a tepid condition 
in the sun, and the pools dry up in the warmest weather. The collections 
were made in September 1907, and contained the following species :— 
Chlorophycez.—- Ulothrie idiospora, sp. n. (with a seriate development of 
akinetes), Zygnema leiospermum, De Bary (in small quantity but in a 
fructiferous state).
