Between the two netted surfaces the sponge sub- stance is formed of loose curving meshes of loosely aggregated bundles of long simple fibres, sparsely .mixed with spicules of other forms. This sponge seems to live fixed to a stone. There are no anchoring spicules, and the bottom of the vase,. Fig. 67.—Asl-onema seUtbahnsc, Kent. One-eighth the natural size. (Xo. 25, 1S70.) which in our two specimens is a good deal con- tracted and has a square shape something like an old Irish 'mether,' has apparently been torn from some attachment. This fine species was named Askonema setubalense, and very briefly described from a specimen in the Lisbon Museum by Mr. Saville Kent, in a paper in which he noticed some.
