528. 5. Cladopora multipora. (Pag- 140.) 
A part of a broken and macerated specimen, showing its irregularly reticulated character. 
A fragment showing the terminations of several small branches, with a portion enlarged 1 6 f. 
A fragment enlarged, showing the forms of the mouths of the cells where little worn. 
A similar portion enlarged, from a surface somewhat more worn than the preceding specimen. 
A fragment where the surface is much worn, presenting simple circular pores on a smooth surface. 
A longitudinal section, showing the interior structure of the coral. 
A transverse section of a single stem, showing radiating tubular cells. 
529. 6. Cladopora macrophora. (Pag- 140.) 
A fragment of a frond having the cells filled and solid, separating in prismatic forms. 
A portion enlarged, showing the structure. 
530. 7. Cladopora reticulata. (Pag- 141.) 
A part of a large frond, showing the branches and reticulations of the natural size. 
An enlarged portion, showing the form and arrangement of the cells upon the surface. 
A similar enlargement where the surface is worn. 
A longitudinal section enlarged, showing the interior arrangement of the tubular cells. 
A fragment of another frond having only six longitudinal rows of pores on the branches, which gives a 
greater lateral distance between the openings on the surface, though presenting no appreciable dif¬ 
ference in the longitudinal distance. 
531. 1 . Limaria ramulosa. (P a g- 142.) 
A single bifurcating branch of this species, somewhat worn. 
A fragment which is tricliotomous. 4 c. The surface enlarged. 
The end of a stem enlarged, showing the structure. 
532. 2. Limaria fruticosa ? ( Pag. 143.) 
A fragment of the natural size, showing a disposition to branch in a palmate form, the section above 
showing five distinct centres, from which the cells radiate. 
A portion of the surface of the same enlarged. 
533. 3. Limaria laminata. (Pa?. 143.) 
The uneven upper surface, showing the apertures of the cells. 
A vertical section, showing the interruption in the growth of the enveloping laminse. 
The apertures of the cells enlarged, when little worn. 
The apertures of the cells as they appear when much worn.
