Burchardt. The spiculation is practically identical, and there seems little importance in the 
varieties distinguished. 
The maximum height is 8 cm. ; the longest diameter of the disc is about 9 cm. ; the 
longest diameter of the attaching base is about 6.5 cm. 
A small colony from Station 279 Roma, along with a larger colony of S. trocheliopho¬ 
rum var. minus , is rather harder and less rubbery than is usual in this species, as is the other 
specimen, perhaps due to previous drying. The autozooids are very clear, up to ro to a centi¬ 
metre. The siphonozooids are small and indistinct, generally one between two autozooids, but 
occasionally two or three. The sterile stalk has a height of 2 cm., and the projecting disc with 
a slightly folded margin has diameters of 3.1 and 2.4 cm. 
A young mushroom-shaped colony with a total height of 2.3 cm., of which 1.9 is stalk. 
The other dimensions of this substantial stalk are about 2 cm. by 1 cm. The diameters of the 
capitulum are 2.5 cm. and 2.3 cm.

It has seemed to us necessary to establish a new variety for numerous specimens whicn 
agree on the whole with A trocheliophorum Marenzeller, but differ in the following respects : 
( a ) there are none of the large lemon-shaped multituberculate spicules ; 
( b ) the majority of the more or less oval spicules show two median zones of low warts and 
warts at each end, but these warts are very often simple, and the whole spicule is, as it 
were, arrested at a young stage; 
(z) the margin of the disc is much less folded and projects less; and the majority of the colonies 
show a deep somewhat reniform incision at one side. Among the younger colonies there are 
fungiform specimens with the margin of the disc entire. 
It may be noted that the variety and the more typical form may occur at the same 
station, but the differences are not growth characters, being seen on large and small specimens alike. 
Interesting on account of its form, but otherwise typical, is a colony (figured) from 
Station 60, Haingsisi. Rising from an expanded common stalk, there are three independent 
stalked capitula, the largest of which has a disc of 4.9 cm. by 3.4, borne on a stalk about 
2.4 cm. in height and 2.8 in maximum diameter. The two larger capitula show very markedly 
the characteristic lateral incision, while the third shows it incipient.
