Biyozoa. 469 



Ooecia with a similar form and size of aperture have hitherto 

 only been found within the family Reteporidae; namely in the three 

 species Retepora novœ zelandiœ, R. soladeria and R. imperati, of which 

 I have only been able to examine the latter. The ooecia are here 

 very much compressed, avicularia-like, and therefore provided with 

 a very long narrow aperture, which in old ooecia becomes closed 

 by means of a calcareous lamina.
