fig. 2.
A small, low, massive specimen, with a small lateral unarmed vent
and very reduced cloacal cavity. The quadriradiates are sagittal,
those of the outer surface very large; diameter of rays about
•04 millim., the facial angle nearly 180°, the apical ray in tho same
plane as the laterals; the deep quadriradiates have a somcAvhat
smaller facial angle and more slender rays, and the apical ray often
projects well f o iw a r d r a y s almost straight. The triradiates form
a thin layer on the inner wall, where their rays measure only
about -01 millim. in d iameter; they have a facial angle of about
160°; in the deep parts they are subregular, sparsely scattered
amongst the quadriradiates, and the rays measure about -02 (sometimes
-025) millim. in diameter; rays approximately straight.
Colour (in spirit) white.
This forna difiers from vars. perimina and arahica of Häckel (I. c.)
in the massive shape of the sponge, and in the larger size, as compared
with the quadriradiates, of the deep triradiates. I n ’the comparative
straightness of the rays it agrees Avith var. arahica and
var. mascarenica, mihi (see this Report, Western Indian Ocean
d istric t); but difi'ers from the latter in the smaller diameter of the
rays of the large quadriradiates, in the apparent smoothness of the
cloacal surface, and the massive form.
