parison was made with Poro, New Caledonia 
material leg. Grunow in the British Museum 
N.H., and in Grunow’s herbarium in the 
Naturhistorisches Museum, Vienna. All had the 
same cushion form, often with short promi- 
nences 0. 5-1.0 cm high on the upper side. 
The degree of compactness varied considerably. 
The filaments were commonly clavate at the tips, 
often irregularly so and lobed, leading to ir- 
regular branching, although the basic branch- 
ing was dichotomous. Whereas the filaments in 
the general mass were 100-200p diam, in these 
tips they commonly ranged from 150 to 400p 
and, if lobed for forking, to 62 5 p. Cross-walls 
were very irregularly placed and were seldom 
seen near the tips, often not for distances as 
much as 1 cm from the tips, so that branching 
and rebranching might occur several times be- 
fore a cross-wall intervened. 
The writer is reluctant to follow Papenfuss’ 
(1950) relegation of these plants to Cladopho- 
ropsis, not having had field experience with 
them. So far as he can see, the branch tips of 
the erect forms, where the plant shape is estab- 
lished, are relatively free from associated sponge 
tissue, and the plant form does not seem to 
vary with the degree of sponge investment. As- 
sociation of other green and red algae with 
sponges is often met in the tropics, and no 
special plant form appears to result — notably, 
indeed, in the case of Cladophoropsis itself, in 
Caribbean waters.

This genus always seems difficult, the species 
ill-defined. While other genera, such as Micro- 
dictyon, sometimes show boodleoid prolifera- 
tions, it is not these which cause the trouble, 
but rather tussocks which seem generically char- 
acteristic but specifically intermediate.

in fact, though to a lesser degree, many mem- 
bers of the genus) proliferate very considerably 
out of the initial plane, sometimes appearing 
with plane blades, sometimes simulating minute 
Boodlea plants.
