Gelliodes filifovmis nov. sp. 
Perseveraiice Harbour. 10 20 f. Campbell Island. Sandy mud. 9.XI,1914. 
Sponge long, cylindrical, quite cordshaped. Length 150 mm, 
greatest thickness 6 mm, tapering somewhat towards the distal end, 
where it only attains a thickness of ca. 2,5 mm. Specimen in hånd 
macerated, only skeleton retained. 
Oscula are found here and there, 
diameter ca. 1 mm. Consistence 
very elastic, soft. Colour light 
gray. Very finely hispid, from 
which it is, however, not to be 
concluded that the sponge also 
would have been hispid, if the 
. dermal membrane had been in- 
tact. 
Skeleton (fig. 12) consists of 
spongin-fibres, which do not dis¬ 
play a distinction between prim¬ 
ary and secondary fibres, since 
both thick and thin fibres may go in every direction and may 
connect with other fibres, thick or thin ad libitum; thickness very 
\arying from ca. 20 130 Width and shape of meshes also very 
varying, so that no distinet plan of structure can be recognized. 
From 0 to 6 spicules are lying side by side in the rows, com- 
pletely enveloped in spongin. 
Spicules: (fig. 13a b) 1. oxea, rather clumsy, abruptly and 
often sharply pointed; length ca. 75 f.v by ca. 10 2. sigmata, 
Dften contorted; rather scarce; length ca. 25—50 p by ca. 2 p. 
Many other spicula-forms (tylostyli, oxea etc.) are found in 
^uite as great a number as the proper oxea enveloped in the 
Jpongin-fibres; but as they often oceur isolated outside the fibres, 
)r only partly enveloped by spongin and then directed rather by 
vhance in relation to the direction of the fibre, it is easy enough 
o declare these spicula-forms as foreign; then the megascleres 
troper are always directed parallel with the fibre and completely 
mveloped by spongin. 
This species differs from the foregoing species, 1. in a denser
