that they should in the meantime be kept apart. Of the former 
class of bodies one of the most frequently present is apparently 
a species of Chlamydophrys, Cien.,! while as representatives of 
the latter we have various zoosporic forms characterised by the 
possession of a differentiated cell-wall, and by the fact that in 
the process of multiplication the line of division is longitudinal 
and not transverse to the original long axis of the body,.- 
and starts from the point of emergence of the flagellum 
(Fig. 24).

Another characteristic organism, occasionally present in con- 
siderable numbers, appears in the form of peculiar, somewhat 
erescentic, colourless cells, which closely resemble certain 
fungal conidia, and are frequently aggregated in linear series 
(Fig. 25).

In some cases, too, a peculiar form of sporangioid structures 
makes its appearance either on the same basis with the charac- 
teristic sporangia, or apparently replacing them. In colour they 
vary considerably, in some cases being pale buff, in others 
salmon-coloured, and in others orange or red. ‘They are always 
of relatively small size, of irregular outline, and unprovided with 
a pedicle (Fig. 26). 
Their texture is firm, and they have a more or less distinctly
