1. Zoarial fragments, natural size. 



2. A bifurcated branch, X12, with the peristomes arranged 



in transverse rows. 



3. Same specimen as Figure 2, X 25. Some of the tubes are 



operculated. 



4. Portion of a Ijranch, X25, showing two denticulated 



eleocellaria. 



5. A branch, X25, illustrating that the eleocellarium results 



from the union of an orifice with the proximal pore. 



6. Zoarial surface, X25. The peristomes are arranged in 



quincunx. 



7. Example, X6, with the zoarial base somewhat expanded. 

 S. Branch, X12, with peristomes arranged in cjuincunx. 



Lower Cretaceous (Aptian): Faringdon, England. 



Figs. 9-17. Laierocava intermedia, new species 86 



9. Two fragments, natural size. 



10. Zoarial fragment, X12, showing that the frontal face 



is covered bj' mesopores; the celluliferous faces are 

 lateral. 



11. The terminal branch of a specimen, X12, with peri- 



stomes all around the colony. 



12. Lateral celluliferous face, X25. 



13. Frontal face, X25. 



14, 15. An ovicelled specimen, X12 and X25. 

 16, 17. Example, X 12 and X25. The ovicell is placed on the 

 frontal face among the mesopores. The two branches 

 are petal opor old.
