three-lobed, three coni radiating from one common base; the other 
smaller specimen is ca. 20 mm high, 15 mm in diameter, the 
bigger 42 mm in greatest extension. Surface even. Subdermal cav- 
ities are seen through the covering dermal membrane, ca. 0,5 mm 
in diameter. Colour reddish-gray; superficial layers of sponge filled 
up with foreign bodies (sand grains etc.).

Skeleton: takes a middle position between Gellius and Gelliodes, 
on account of the faet, that the majority of the spicules are lying 
disorderly, while a good deal, however, are placed in more or less 
distinet fibres, which still are not modelled in the characteristic 
way as in the typical Gelliodes species. I therefore think it safest 
to refer the species in hånd to the genus Gellius. There is a 
tendency to a ringformed arrangement of oxea about the canal- 
system. 
Spicules: (fig. 9a—b) 1. oxea; slightly curved, evenly taper¬ 
ing towards both ends, most often ending in a very sharp point. 
Length 115 p by 5,5 p, which is the most common size, rather 
constantly found. 2. sigmata seem to be of two kinds; the one 
size varying from ca. 12—25 p by 0,7 l,o p\ the other 35 70
