I believe I am right in referring the material in these samples to this little-known species. The filaments were rather variable in width, many of them being 10-11 fx, but others as narrow as 7 or 8 /x. The cells in many of the filaments were very flat (one-third to half as long as broad) (cf. Fig. 10, A), whilst in others they were much longer 36.
