The figures in this plate represent, for the most part, full-sized or large 
individuals under a power of 400 diameters. No. 9, Navicula Macida, is 
represented under a somewhat higher power ; but I believe there are 
individuals of equal size under 400 diameters. 
The remainder of the new forms which I have described in the Glenshira 
Sand, and several of which are very curious, will be figured in the next 
Number of the Journal.
