by a layer of sarcode. The length of the single specimen,
which represents this species, is 80 mm, the 8 mm long
pe-dicle included. The pedicle is free from processes. The
diameter of the sponge is about 5 mm, that of the pedicle only
2 mm.
Skeleton. The skeleton consists of acuate (and rarely
subspinulate) spicules and of inequianchorate spicules varying
in size.
The acuate spicules (Plate 25, fig. 66) of the axis as well as
those of the processes are parallel. Those of the processes are
much more slender than those of the stem. They are quite
smooth and straight, the length being 0,85 mm.
The inequianchorate spicules (Plate 25, fig. 67—69) are very
characteristic for this species. The smaller end is furnished
with a bow-shaped appendix, attaelied to the end by a short
shaft, which is curved towards the larger end. The length of
these spicules is about 0,025 mm.
Colour. The colour is light-grey with a tint of yellow, when
preserved in spirit.
