Special description. 
The Sponge described by Carter (unhappily not illustrated by 
him), is distinguished from other Suberitides by the peculiar shape 
of the head of the spinulates. It is elongated, oval or more ellip- 
soidal, as is to be seen in the figures 137—139 on plate IV. The 
shaft of the spieules is subfusiform, for the diameter in the mid- 
dle is only a little greater than just beneath the head. 
I have found, but very rarely tr?. f° (sp.); it may be that they 
don’t belong to the Sponge. Üarter gives the following description: 
„Form montieular. Colour grey-black. Surface even. Vents, one 
large at the summit, fringed. the rest small, on the sides. Texture 
soft, matted.’” These words can be applied perfectly well to our 
specimen.

Special description. 
There is much resemblance between this Sponge and Hym. (Su- 
berites) virgultosa of Bowerbank. The surface is corrugated nearly 
as in the specimen represented by Bowerbank in Pl. X\XXV (Mo- 
nogr. Br. Spong. III). The appearance of little spines on the in- 
flato-fusiform spieules [tr?. f° (sp.) and ac? f? (sp.)] brings the Sponge 
to another species. Again in our Suberites, the osculum, (nearly 
always only a single one) is fringed, as in S. montiniger. Whether 
these fringes are also present in the living state, or whether they
