CORALS AND BRYOZOA. 31 



Bryozoa on that occasion inclined liini to believe that the forma- 

 tion was Pliocene. It is not known to be older. Professor 

 ZittePs specimen was from the Lower Miocene or Upi^er Eocene 

 beds of the mouth of the Waikato River. Those now to be 

 described are from the Te Ante limestone, Mount Vernon, Wai- 

 pukurau, Napier; Formation No. III., Upper Miocene of New 

 Zealand geologists. This would be in keeping with the position 

 of the organisms in Europe; and it is a fact of no ordinary interest 

 in natural science that two such peculiar closely-allied organisms 

 should flourish in the same epoch in such remote seas as Britain 

 and New Zealand. At one time I Avas of opinion that we had 

 an existing species in the Australian seas, but this was certainly 

 an error. 



I have adopted D'Orbigny's name, Fasciculiporce (1839), for 

 the genus, instead of M. -Edwards's Fascicularia, which was not 

 published (being only MS.), as the same name had been used by 

 Lamarck to describe a genus of corals allied to Shjlina, and now 

 included with them. Fascicularia is, in any case, so close to 

 Fasciolaria that its use would lead to confusion. 



Fasciculipora. 



Zooarium composed of bundles of tubes formed of radiating 

 fasciculi, united either by tabulse or to each other. Pores simple. 



Fasciculipora intermedia, n. s. Zooarium irregularly hemi- 

 spherical, with distant or close radiating fasciculi, with a distinct, 

 rather thick epitheca, on which the marks of the tubes appear 

 plainly. Tabulae irregular. Pores of one kind only, but occa- 

 sionally small, hexagonal, with what appear like interstices. 



There are three specimens in the collection. Two are regu- 

 larly tabulate, and the third has scarcely any of these septal 

 divisions. They are sometimes 2 millimetres in thickness, or 

 dwindle down to mere laminae. In one specimen the tabulae are 

 in regular semicircular divisions. In another, they break off 

 irregularly. The casts of a little colony of Balani in one of 

 the specimens shows that it began its structure as a parasite.

Fasciculipora ramosa. Zooarium composed of fine, slender 

 fasciculi, which ramify in all directions, anastomosing or sending 

 off little short branches, which terminate in clusters of pores ;
