FASCIGERID^. 
The Super cytis of Macgillivray,^ from the Middle Cainozoic of 
Victoria and South Australia, is a Biscofascigera^ as the apertures 
are terminal and not spread over the front surface of the zoarium.

Affinities. 
This species is characterized by the tooth-like elevations on 
the upper surface, which give it somewhat the appearance of 
Biscocytis ; but the irregular distribution of the apertures on the 
upper surface (as shown in Vine’s flgure, op. cit. flg. 12) is quite 
different from the arrangement in Biscocytis^ where (as illustrated, 
for example, in B. esseniensis, Sim., Bry. Essen. Griins. : Verh. nat. 
Ver. preuss. Eheinl. u. Westph. vol. xxviii. (1871), pi. iii. flg. 2d) 
the apertures open on the outer margin at the ends of bundles.
