slightly attenuated. The spicules agree well with those figured 
by Carter op. cit. The spined acuate are 0,2—0,3 mm in length, 
the obtuse spicules 0,25 mm. The anchorate spicules differ a 
little from those described by Carter. In our specimen there 
are two kinds of anchorate spicules, the larger perfectly agreeing 
with those figured by Carter, thev are 0,05 mm in length; the 
spicules: of the other kind are only 0,02 mm in length bum 
shape they are quite like the larger ones. The sponge is cream- 
coloured.

Melonanchora elliptica, Carter, Ann. Mag. Nat. Hist., Ser. 4, Vol. 14, pag. 
212, Plate 13, fig. 6—12, and Plate 15, fig. 35 a,b; 
Deep-sea sponges from the Atl. Ocean. 
'The consistency, the form and the colour agree totally with 
those of Melonanchora elliptica Carter. The surface is furnished 
with tubercles, and the dermal layer is easily separated from 
the other soft sponge-body. Our specimens were growing freely. 
All our specimens are fragments. 
Skeleton. The skeleton consists of obtuse spicules, of 
melonanchors, of equianchorate spicules. 
The obtuse spicules (Plate 25, fig. 51) are smooth, slightly 
curved or straight. The ends are sometimes slightly inflated. 
Their length is 0,65 mm. 
The melonanchorate spicules (Plate 25, fig.52) are very numerous, 
their length being 0,07 mm. 
The eqwianchorate spicules (Plate 25, fig. 53—55) are of two 
kinds, the larger 0,06 mm in length, the length of the smaller 
being only 0,015 mm. 
Colour. Grey, when preserved in spirit.
