The autozooids are smaller and more numerous than in most of the specimens. The 
numerous siphonozooids are also rather smaller, but just visible to the naked eye. The colour 
is a creamy light brown. The spicules agree well with the typical L. crassum types. The great 
majority are the short stout barrel-like forms with two zones of compound warts and warted 
ends (0.15 X 0.08 mm.). The long pointed spindles covered with zones of warts were also present 
and less numerous pseudo-clubs. 
Another interesting colony, from an unrecorded locality, of Sarcophytum-appearance, almost 
exactly like Burchardt’s figure of A. glaucum , but agreeing in its spicules with L. crassum , 
which is a variable species. We do not think that the fungoid form of a relatively young colony 
has any significance. In this case a longitudinally grooved stalk (8 cm. in height) leads to a 
folded capitulum, with diameters of 7.5 and 4.5 cm. The autozooids are numerous, almost wholly 
retracted; the siphonozooids are very inconspicuous, only in some places to be detected (with 
difficulty) with the naked eye. The spiculation of the capitular region includes: 
( a ) broad multizoned spindles with compound warts; 
( b ) narrow multizoned spindles with compound warts; 
(c) a few pseudo-clubs; 
( d ) some almost oval forms derived from [a ]; 
( e ) some narrow spindles with simple prominences, not very numerous ; 
(f) a few small narrow spindles with simple blunt prominences, exactly as Marenzeller figures, 
apparently young forms of ( e ). 
The stem shows predominantly broad ovals with two zones of compound warts, and 
other compound warts clustered at each end. There are also approximate double-spheres and 
spheres covered with compound warts. 
A young colony, from Savu, standing 3.3 cm. in total height, in which the sterile trunk 
counts for 1.2 cm. The trunk is somewhat flattened at right angles to the longer axis of the 
colony, and has a maximum length of 5.6 cm., and a breadth of 1.2 cm. The disc shows about 
a dozen folds and lobes, rising vertically and somewhat flattened in the plane at right angles 
to the flattening of the trunk. The autozooids are numerous, and in some parts crowded ; the 
numerous siphonozooids between them are just discernible with the unaided eye. The spicules 
include (a) large numbers of stout broad spindles and ovals with crowded zones of compound 
tubercles, five zones being common ; ( 6 ) more elongated spindles with as many as six zones of 
less massive warts; (z) various young forms of both types with incipient warts ; ( d ) small spindles 
with two zones of short warts; ( e ) a few pseudo-clubs. 
This colony shows some points of resemblance, especially in its mode of growth and 
spicules, to Whitelegge’s L. hedleyi ; but it seems still closer to the variable L. crassum. What¬ 
ever view be taken as to the separateness of the species, L. hedleyi and L. crassztm must be 
close together. 
From the same locality a large spreading colony, with a maximum diameter of 8.8 cm. 
A sterile trunk of about 5 cm. in height leads to the massive disc covered with conical lobes, 
often about 1.7 cm. in length.
