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 dia- 
meter 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 mnequianchorate spicules (Plate 25, fig. 61—69) are very 
characteristic for this species. The smaller end is furnished 
with a bow-shaped appendix, attached 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.
