A young colony, mushroom-like in form, with a stalk 1.4 cm. in breadth, rising to a 
height of 2.5 cm., and bearing a capitulum, with diameters 2.5 cm. and 2.3 cm. The colour is 
grey brown. The autozooids are very distinct, about 10 to a centimetre near the margin; the 
siphonozooids are numerous and well-defined. 
The spicules of the stalk are chiefly broad heavily warted spindles with pointed ends, 
which we take to be one of the few clear differences between V. glaiicum and S. trocheliophorum. 
A common length of these spindles is 0.4 mm. On the capitulum most of the spicules are 
relatively narrow spindles, usually but not always with simple prominences. There are also small 
pseudo-clubs, and a few crosses. 
Miss Pratt notes as characteristic of this species — the slimy secretion, the green 
colour, the soft flexible texture, the large size of the autozooids, and the clearly defined 
siphonozooids. Our specimens are markedly smooth and soft; some are greenish ; the autozooids 
are very long. 
We are inclined to emphasise the abundant occurrence of three types of spicule; 
(а) large substantial spindles variously covered by compound warts or conical prominences; 
( б ) delicate, slightly spinose, often slightly curved spindles; 
(c) warty pseudo-clubs, many of them long in proportion to their breadth. 
As an instance of the intergrading of genera we may refer to a number of young 
colonies which we regarded at first as belonging not merely to a different species, but to the 
genus Sinularia (Sclerophytum). But further examination has convinced us that they are merely
