5. Pustulopora clavaeformis, n. sp. (Plate XIV.) 



Zoarimn simple and club-shaped, or composed of three or four 

 short club-shaped lobes ; mouth of cells circular, slightly raised ; 

 surface finely punctured ; oooecia ? 



Hah. Algoa Bay, South Africa. 



6. Pustulopora intricaria, n. sp. (Plate X. figs. 1 (pars) & 4.) 



Zoarium constituted of short clavate branches, very irregularly 

 disposed and united by frequent anastomoses, so as to form a 

 dense intricate growth ; cells slightly ventrieose, deeply immersed, 

 sometimes produced into rather long straight projecting tubes; 

 oooecia ? 



Hah. South Australia (Gould). 



This remarkable form is at once distinguished by its mode of 

 growth in dense intricate masses of considerable size, and consisting 

 of short branches spreading in all directions, and forming intricate 

 anastomoses. In one specimen, about an inch in diameter, there 

 may be seen in the interstices of the growth abundance of Idmoneci 

 parasitica, which in many places seems to be as it were continuous 

 with the substance of the Fusfuhpora. 



Other sjyecies noticed hy Authors or not ftdhj determined. 



7. Pustulopora gaUica, D'Orb. (sp.). 



" Three times as large as P. prohoscidea, with numerous cells pro- 

 jecting on all sides, and much longer than the diameter of the 

 branches — much crowded, especially at the extremity of the 

 branches."

8. Pustulopora indica, D'Orb. (sp.). 



" Zoarium as slender as in P. prohoscidea, but with eight lines of 

 cells, all visible on the exterior, notwithstanding the transverse 

 rugse which occupy the spaces between the apertures."
