Zoologi/.'] NATURAL HISTORY OF VICTORIA. [Polyzoa. 



Port Phillip Heads. 



A small and very beautiful species, of whicli I have only seen 

 one specimen. In this there are six or seven bundles of zooecia 

 spread over a small calcareous nodule and connected by a cal- 

 careous punctate or perforated crust. When viewed vertically, 

 they suggest a resemblance to a composite flower on the end of its 

 pedicle.

 FASCICULIPORA FRUTICOSA (McG.). 



Description. — Zoarium branched, the main branches mostly horizontal, with 

 numerous short branches turned upwards, the scondary branches consisting' of 

 bundles of zooecia, all opening by closely packed prismatic orifices ; surface punctate, 

 faintly sulcate longitudinally and (especially in older parts and on the back) 

 transversely corrugated.

Port Phillip Heads. 



Distinguished from F. o'amosa by the much smaller number of 

 zooecia in the narrower Ijranches. Some of my specimens form 

 dense, shrub-like tufts an inch in diameter.
