The ovicell is irregular and located on the zoarium. The oeciopore is sub- 
central. The tubes are very salient at their proximal extremity; they are isolated 
or fasciculate. 
In studying the anatomy of Tubulipora organisans D’Orbigny, 1839, 
Jullien 1 wrote: 
J'ai vu que l’ovieelle constituait une vraie genesie femelle depourvue de polypide, contenant 
une tres grande quantite d’ovules qui y sont fecondees et en sortent a l'etat de larves deja 
tres developpees. 
The limits of this family have never been very precise; all of the old authors 
understood it in a different sense, adding or eliminating genera according to their 
personal opinion. The zoarial form and the mode of aggregation of the tubes 
were the only characters studied. A discussion of priority is therefore useless, 
since we now regard the ovicell as the essential and most important character. 
In the establishment of the new genera we must consider the form and posi- 
tion of the oeciopore, which is in rapport with the function of the escape of the 
larva. Unfortunately, very often sufficient material for a complete study is lack- 
ing. As in the Cheilostomata, we must also regard the function of calcification. 
We consider the genus Tubulipora Lamarck, 1816, as quite a natural one and 
we accept the word “ Tubuliporiclae ” for the family, although the genus Iclmanea 
is the more important in time and in space.

Many of the Tubuliporiclae are provided with “ pores which are the orifices 
of the special tubes of whose function we are absolutely ignorant. We give 
them different names according to the case and to their nature, but we can consider 
them only as variations determined by the function of calcification. They appear 
to furnish secondary generic characters and nothing more.
