iulnatc proboscinoid shoots, which end in short groups of openings. 
The affinities of this genus depend on whether these groups of 
openings are to he regarded as groups of apertures or as the broken 
tubes of the zooecia. The latter explanation seems the more 
probable, especially in the case of F. megeera ; for so far as may 
be judged from Lonsdale’s ^ figure, the groups look like the 
transverse sections across broken Entalophoroid shoots. 
If such be the case, then Filifascigera is founded on the adnate 
base of an Entalophorid, though not of Entalopliora^ since in the 
known bases of that genus there are numerous apertures along the 
basal shoots or on the disc. 
If, however, the groups of orifices are true apertures, then the 
genus is an Osculiporid, with an adnate zoarium composed of 
l)roboscinoid shoots.
