Heliolites subtubulata, McCoy. Tubes more 
distant and the crenulations or septa nearly 
obsolete. 
Heliolites tubulata, Lonsd. sp. (Siluria 2nd ed. 
pl. 39, fig. 3). The prominent edges of the 
small close cups easily distinguish this.

Heliolites megastoma, McCoy (Siluria, 2nd ed. 
Foss. 27, fig. 7. M. Edw. and Haime, Mon. 
Brit. Fos. Cor. t. 58, fig. 2. Very large cells 
evenly scattered, mark this fine species— 
equally abundant in the Dudley limestone. 
Favosites crassa, McCoy. Subcylindrical curved 
branches like F’. cristata of the Wenlock. 
Favosites alveolaris, Goldf. Pet. Germ. t. 26, 
fig. 1. Much like the common £ Goth-

cognize this excellent species by its ragged 
crenulated edges to the tubes. 
Favosites Gothlandica, Linn. sp. Siluria 2nd ed. 
Foss. 17, figs. 2, 3. A species of coral which 
has the widest range—from America to 
Eastern Europe: and from the Lower Bala 
to the Carboniferous.

often rising into a subpyramidal form, and 
covered with unequal clusters of pores— 
the fertile ones largest—like the drone-
