thickest in the middle, sharp-pointed; sometimes beginnings to sub- 
tylostyli are found; length about 700 most common, but the styli 
may vary from ca. 500— 900 /f, by a thickness of 14—25 2. O x e a

middle towards the pointed apices, varying in length from 170—

Axinella globula nov. spec. 
(Fig. 28.) 
2 miles East ofNorthCape. 55 fathoms. Hard bottom. 2/1.1915. 
One little specimen, hemispherical, torn loose from the body of 
attachment; 13 mm in largest diameter, 8 mm high; numerous 
small apertures up to 0,25 mm 
in diameter are seen everywhere 
on the surface, which is very 
hispid. Consistence nearly stony, 
colour grey. 
The skeleton is distinctly 
radially arranged; the main 
fibres run unbroken from the 
centre of the sponge vertically 
outwards to the surface, every 
now and then giving off new 
branches at very narrow angles 
to fill up the ever increasing 
spaces between the original 
fibres; most spicules in the 
fibres are arranged so that they 
point obliquely outwards in a 
true Axinelloid manner; some spicules, however, are placed so, 
that the point is directed vertically outwards from the fibre in an 
Ectyonine manner; these latter spicules always reach the neigh- 
bouring fibres, thus adding to the strength of the entire skeleton. 
No special dermal skeleton is found, the distally placed spicules 
in the fibres pierce the dermal-membrane, making it hispid. 
Spicules. Styli (fig. 28), somewhat varying in appearance, in 
most .cases somewhat crooked a little above the base, only rarely 
nearly straight; they are generally thickest at the base and at the
