PLATE 26. 
Fig. 1. 111. 1. Escharopoka recta. (Pag. 73.) 
1 a. Specimen natural size ; the lower extremity expanding to form the rootlike processes, and terminating 
abruptly above. 
1 b. An enlarged portion, showing the arrangement of cells, which are apparently in ascending spiral lines 
around the axis. 
1 c. A small specimen, entirely cylindrical, tapering above to an acute point. 
1 d. An enlarged portion, showing the oblique elevated lines crossing the surface, in the spaces between which 
are the openings of the cellules. These lines are partially obliterated in worn specimens. 
1 e. The root or attaching part of this coral : the branches embrace a portiun of stony matter. Upon the base 
of the broken shaft of the coral, a portion of the surface is marked as the specimen 1 a. 
1 g. A longitudinal section of one of these corals, a little on one side of the centre, showing a few ranges of 
the apertures of the cells, and the diverging and ascending tubes on either side. 
Fig. 2. 112. 2. Escharopora recta, var . nodosa. 
Fig. 3. 113. 5. Stictopora? acuta. 
3 a. A small fragment of limestone, with several branches of the coral upon its surface. 
3 b. An enlarged portion of one of the branches. 
3 c. Transverse section of two branches of the coral, just above the bifurcation.

Fig. 
4. 114. 6. Stictopora elegantula. Fig. 75.) 
4 a. A small fragment of the natural size, showing the form of branches and arrangement of cells. 
4 b. A small part of the same enlarged. The form of the cells is more rounded than appears in this figure. 
4 c. The entire specimen 4 a enlarged, to show more distinctly the arrangement of the cells, the striated 
margin, etc. 
4 d. A small specimen, bifurcating above, with the celluliferous crust nearly removed, a few of the cells only 
remaining near the base. The longitudinal and concentrically transverse striae are clearly shown. 
4 c. A small portion of the same enlarged. 
if. A more elongated specimen ; the branches narrow, and bifurcating more nearly like the last species. The 
celluliferous crust is removed, leaving the central striated axis. 
4 g. A small portion of the last enlarged. 
Fig. 5. 115. 2. Gorgonia? perantiq.ua. (Pag. 76.) 
5 a. The specimen, natural size. 
5 b. A portion of a branch enlarged, showing the openings upon the two sides of the axis. 
*** This species proves, on farther examination, not to be a Gorgonia. 
Fig. 6. 116. 1. Aulopora arachnoidea. (Pag. 76.) 
6 a. The dorsal valve of Delthyris lynx , having the inner side of the shell spread over with a fine web of this 
little coral. 
G b. A magnified portion, showing the form of the cells, openings, etc. 
6 c. Two of the cells still farther magnified. 
Fig. 7. 117. 1. Alecto inflata. ( Pag. 77.) 
7 a. Dorsal valve of Lsptana alternata, on the outer surface of which this coral is affixed. 
7 b. Two of the tubes magnified, to show their form. 
Fig. 8. 118. 1. Intricaria? reticulata. (Pag. 77.) 
8 a. A small fragment of the rock covered by this coral, and fragments of one or two other species (nat. size). 
S b. A portion magnified, showing the apertures of the cells, and the mode of branching and anastomosing. A 
small fragment of another coral lies across the specimen. 
8 c. A small portion of a branch still more enlarged, showing the apertures of the cells. 
Fig. 9. 119. 3. Retepora? foliacea. (Pag. 88.) 
9 a. The specimen (nat. size), upon the surface of limestone. 9 b. Surface of the same enlarged. 
Fig. 10. 120. 1. Stellipora antheloidea. (Pag. 79.) 
10 a. Fragment, exhibiting the prominent star-form cells of the natural size. 
10 b. Three of these stars enlarged, showing points or pores upon their upper surface. One of these stars has a 
slightly irregular form in the centre, as if composed of parts of two : this is true of several others. 
Fig. 11. 121. 1. Graptolithus amplexicaule. (Pag. 79.) 
11 a. A group of these fossils ; all the stipes, except one, having been broken off by a fracture of the stone. 
116. An enlarged portion, showing the edges of the sheathing scales.
