It has not, so far as I am aware, been recorded for 

 many localities in England. This may be due to some 

 extent to its very small size and insignificant appearance, 

 partly to the fact that it is extremely susceptible to dry- 

 ness, disappearing beneath the surface of the soil as soon 

 as it becomes at all dry. It seems to require for its 

 development above ground that the soil should be just in 

 the right condition as regards moisture, being neither too 

 damp nor too dry. 



I have found it in the following localities : — 



1. Winsford, Cheshire. On the drying up sediment of 



the filter beds. 1889. 



2. Near Bristol. On the drying up mud left by a road- 



side pool. 1 89 1. 



3. Chapel Allerton, Leeds. In my garden at Bank 



View, on a damp clayey soil all over the garden. 

 1898. 



4. Near Banwell, Somerset. On the drying up mud 



left by a small roadside pool.

 Mr. Wm. West, F.L.S., Mr. Wm. West, jun., B.A., 

 Prof. F. W. Oliver, and Mr. Abbott.
