MADREPORARIA. 



The texture of the section is coarse and open, and the skeletal elements themselves are 

 variable, very stout and very thin flakes and threads being intermingled.J 



This specimen is of considerable interest, not only on account of its growth-form, which 

 recalls the ideal dichotomy of a West Indian Porites, e.g. P. West Indies x. H, but also 

 because of the signs of struggle which can be seen between the Balanids settled upon it and 

 the growing coral, the latter always having threatened to overgrow the former. 



Stout branching forms of Gonioporm are known, for instance, from the Seychelles, 

 Singapore and Samoa, but a definite order of growth forking is not usually apparent. 



The calicles in their younger stages somewhat recall those figured in Vol. IV. PI. IX. 

 figs. 1 and 2, which also referred to a specimen from some unknown locality.
