made, the structure will be seen. For instance, in Iclmonea radians, 

 Lamk„, there are large pores perforating the shell-wall ; and to 

 similar cases in Hornera I have referred in this Journal, vol. xl. 

 p. 678, pi. xxx. fig. 8. 



It is interesting to find the " rays," or hair-like teeth, preserved 

 in the zocecia of fossil Entalophora intricaria ; and. I would specially 

 call the attention of paleontologists to PL XVIII. fig. 4, as this repre- 

 sents a most typical Cyclostomatous form, showing both the usual 

 shell-structure with pores between the zooecia, and also the " rays," 

 which are now known to occur in both of the divisions which I 

 propose to make, though previously they have only been described 

 in the rectangulata, as in Heteropara and Liclienopora. They also 

 occur, however, in a New-Zealand Tubulipora. 



Tubidipora biduplieata and T. Campiclwana are two very interesting 

 species, showing considerable variation in the mode of growth. If 

 the series of specimens had not been moderately large, it is possible 

 that more than two species would have been made.
