36 ON SOME POLYZOA FROM THE QUEENSLAND COAST, 



10. Pustulipora clavaeformis, Bush. 



11. Eetihornera foliacea? MacGUlivrmj. 

 Hob. Port Denison ; a small fragment probably of this species. 



Sub-order Cheilostomata. 



12. Salicornaria tenuirostris, Busk. 



I can find no avicularia on my specimens, but the close 

 correspondence in the form of the cells and the general habit 

 leaves little doubt of the correctness of the determination. 



13. Nellia oculata, Busk. 



14. Onchopora ventricosa, sp. nov., Plate I., fig. 3. 



Cells elongate, projecting a little at the oral end ; covered with 

 irregular granulations ; mouth with a shallow, open sinus in the 

 lower lip. 



An ally of 0. mutica of Busk, (Q. Journ. Micro. Sc, vol. iii., 

 p. 321, pi. iv., figs. 2, 3) but with the cells longer and less crowded. 



15. Onchopora immersa, s/^. nov., Plate I., figs. 4, 5. 



Zoarium dichotomously branched ; branches cylindrical ; cells 

 immersed ; surface ornamented with large pores. 



16. Onchopora granulosa, sp. nov. 

 Cells short, ventricose, cell-wall granulated, mouth not produced, 

 with a shallow sinus in the lower lip. 



Distinguished from 0. ventricosa, by the greater shortness of 

 the cells, and the closeness of the granulations on the surface. 



17. Cabarea rudis, Busk. 

 18. Cabarea lata, -SwsX*. 



19. CeUularia cuspidata. Busk, var. 

 The spine on the upper and outer angle of the cell is extremely 

 short and blunt.
