338 MR. G. S. WEST ON SOME BRITISH 
size, its more copious outer coat, and by its longer and more 
slender pseudopodia. 
This pretty little animal was obtained in washings of Myrio- 
phyllum from some large ponds in Epping Forest. None of the 
individuals observed possessed any green colour, and I was unable 
to detect the presence of any vacuoles. The outer zone which 
envelops the body is very wide, perfectly colourless, and its 
outer surface exhibits an exceedingly delicate fimbriation, much 
more delicate than the fringing of the corresponding structure 
in H. spinifera or H. myriapoda. The pseudopodia are delicate 
strands of protoplasm, with numbers of relatively large granules 
scattered at intervals along their length. 
The extraordinary fimbriated (or ‘spinous’) outer coat of 
H. Pavesii, Garbini (in Zoolog. Anzeig. xxi. no. 575, 1898, 
p- 668, cum fig. 2), is alone a sufficient distinction between it and 
HI. radiata.

All the animals observed were solitary and some of them of 
small size, but otherwise they were exactly like Archer’s descrip- 
tion and figure.

The pseudopodia were granulated, and the investing sand- 
grains of the body-protoplasm were small and compact. I can see 
no difference between this animal and Hleorhanis cincta, Greeff 
(1878), except in the granulation of the pseudopodia.. Perhaps 
the two are identical, and, if so, Greetf’s name will take pre- 
cedence. This Heliozo6n was described originally from the 
Baltic Sea, and has also been recorded from freshwaters in 
Germany.
