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

Our specimens of this species agree very wellwirb 
Heckels description and figures: In the same mannens 
Ascamdra botryoides Ellis et Sol. (Fristedt) the specimens of 
A. complicata, which are all from the expedition of the Vega, 
are congregated, forming tufts of variable sizes or incerusting 
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 103600:

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 length and 7 mm in breadmie 
inner surface is smooth. The outer is rather rough owing to 
the large acerate spicules, and presents a certain resemblance
