The figures in this plate represent, for the most part, full-sized or largeindividuals under a power of 400 diameters. No. 9, Navicida Macida, isrepresented under a somewhat higher power ; but I believe there areindividuals of equal size under 400 diameters. The remainder of the new forms which I have described in the GlenshiraSand, and several of which arc very curious, will be figured in the nextNumber of the Journal. jA^/rJou/r%M.iy.9iIIV.
