upwards the dermal layer. Oscula or pores not visible in 
our specimens. The finest specimen is 40 mm in length; the 
greatest diameter is at the top 7 mm, tapering towards the 
pedicle, which is only 2 mm in diameter. The other specimen 
is a little larger, but broken and not so well preserved as the 
first mentioned. The colour is ash-grey.

Only one specimen represents this new species. The outer 
shape resembles very much that of C. textile Carter. The only 
difference is the pedicle, which is wanting in this species. The 
specimen is attached to a coral. The surface is even and smooth. 
länaverseen neither 'oscula nor pores. oLhe length is 40mm: 
The sponge is cylindrical, the diameter about 10 mm. The 
thickness of the dermal layer varies from 0,5 to I mm. The 
inner portions agree tolerably well with those of C. textile 
Carter. The consistency is the same as of the two preceding 
species of this genus. 
The skeleton consists of spined acuate spicules, hastate 
(mucronate) or obtuse spicules, and of large, and small equi- 
anchorate spicules. 
The spined acuate spicules (Plate 25, fig. 3) are the largest 
and most numerous of the skeleton-spicules. They are always 
a little curved and totally spined, tapering from the round 
base to the pointed termination. The length is very constant, 
0,4 mm, the thickness varies a little. 
The hastate (obtuse) spicules (Plate 25, fig. 4). The spicules, 
so named by me, are both mucronate, hastate and obtuse, in 
this species generally mucronate; but the difference between 
these kinds of spicules is often so little, that I call them all 
hastate. "They are straight, not so numerous as the preceding. 
One termination is generally more slender than the other, 
both terminations being slightly spined. The length is 0,3— 
0.35 mm.
