quadriradiate spicules are not of the same shape as those of
A. canariensis. Besides that the locality, where A. canariensis
has been found — the Canaries, as the naine indicates — is too
distant from the regions, where our specimens were dredged
up, to allow these to be identical with A. canariensis.
As Heeckel under several other species has mentioned
»Connexive Varietäten», tliere is nothing wonderful in finding
such a variety of Aseetta coriacea.
The largest specimen of this sponge, which I have seen,
was round and a little depressed. The greatest diameter about
40 mm.

Fig. 1 a—1 k.
Our specimens of this species agree very well with
II ge c k e 1 ’ s description and figures. In the same manner as
Ascandra botryoides Ellis et Sol. (Fristedt) the specimens of
A. complicata, which are all from tlie expedition of the Yega,
are congregated, forming tufts of variable sizes or incrusting
branches of sea-weeds.
Habitat. Several specimens from Jinretlen, depth 15 fath.,
(1006 V.), and from Pitlekai, depth 10—14 fathoms (1015, 1027,
1031, 1035 and 1036 V.).
Ascandra mirabilis n. sp.
Plate 22, fig. 3—13, Plate 26, fig. 1—2.
This species is represented by only one specimen, forming
an oval tube, 15 mm in lengtli and 7 mm in breadth. The
inner surface is smooth. The outer is rather rough owing to
the large acerate spicules, and presents a certain resemblance
