‘5 mm. in length; occasionally two sporangia have the stalks 
united ; the capilitium and spores are of the usual type of P. com- 
pressum. The var. 3 (figured in the Brit. Mus. Catalogue, Pl. xvi.)

the shape of the sporangium constitutes the only divergence from

Sbliginisty sent me specimens of Mycetozoa from Antigua, which

ith the exception of one which appears to have been not hitherto 
described. Although a single gathering, it possesses reese so 
distinct, especially in the remarkably spinose aie that, r, 
Cran’s approval, I propose to name it as above; the des aiiptioi is 
as follows Plasmodium ? Sporangia chalk- mite, “usually curved 
plasmodiocarps, laterally gina thin ridge, and 
with the base narrow ; sporangium- -wall of two layeie: the outer 
purple membrane ; spores purple, diam., marke with strong 
spines and ridges. ead leaves an Ase is allied t

by Prof. O. Penzig in Java, nee by him in Die Myxomyceten
