spicules are verv like those of the preceding species; the length
is 0,07 mm.
The small equianchorate spicules (Plate 25, fig. 6). The lengtli
of these spicules is only 0,025 mm.

The most common shape of this sponge is that of a
form-less mass, but specimens from the expedition to Greenland
in the year 1883 are ventilabriform, like those of Phakéllia
robusta Bow. The length of the largest specimen is 120 mm,
the breadth 95 mm and the thickness 6 mm. This example
is broken at the margins, being only a fragment of a larger
specimen. The others are thicker, incrusting shells. The colour
of the sponge is dark, when preserved in spirit.

The specimens, representing this species, agree well with
Bowerbank’s description and figures, in form as well as to
inner structure. The surface is corrugated; the consistency
