A MONOGRAPH OF THE TERTIARY POLYZOA OP VICTORIA. 145 



constituted of coalesced, almost completely immersed zooecia of varying lengths, all 

 of which open on the upper flattened side of the fasciculus or at the extremity. 

 Dorsal surface rounded, even, longitudinally striated and minutely punctate. 

 Ooecia (when present) hemispherical, at the base of the fasciculi, and usually on the 

 upper surface." — (Busk).

Zoarium stalked, expanded above into a disc, on the edge of which are the 

 openings of closely-packed zooecia. Prom the upper surface of the disc, and 

 slightly within its outer edge, arise eight compressed fasciculi, which are simple or 

 bifid or, in one case, trifid. They rise abruptly from the base so as to give the 

 zoarium a deep cup-shaped form. Their lower inner edges almost meet in the 

 centre of the disc. The zooecia open along the lower and outer edges and extremities 

 of the fasciculi. The inner surface of the fasciculi is striated, owing to the incom- 

 plete fusion of the zooecia. Between the fasciculi the surface of the disc is marked 

 out by a single row of large oblong transversely-placed pits, the ridges between 

 which run up into the sides of the fasciculi. Ooecium an inflation in the centre of 

 the colony.

The broken stalk of attachment is clearly visible in one specimen, and there 

 can thus be no doubt that the zooecia open on the lower and not on the upper side 

 in the specimens. It does not then seem quite certain that it is D'Orbigny's species, 

 as in the latter the zooecial openings are on the upper side of the fasciculi, a 

 character which is shown by some recent specimens from New Zealand in the 

 collection. The identification was queried by Dr. Maotiillivray in some of his lists, 

 so that he would, perhaps, have remarked upon it. 



Pasciculipora, D'Orb. 



" Zoarium erect, simple or branched or lobate. Zooecia opening only at the 

 extremities of the branches or in one or more regular series below the extremity."
