54 BRITISH FOSSIL CORALS. 
VIII. Corats From THE Eocene or tHe [stp or Wicut AND FROM THE LONDON CLAY. 
Orvpier—ZOANTHARLTA. 
Famiry—TURBINOLIDA. 
Tribe—TuRBINOLINA. 
Genus—TURBINOLIA. 
1. TuRBINOLTA AFFINIS, Dyncan. Plate IX, figs: 12583. 
The corallum is slightly truncated inferiorly, and it is conical low down, but cylindro- 
conical above ; it is symmetrical and very small. 
The costae are well developed and obtuse ; the largest are swollen out inferiorly, and all 
gre moderately prominent ; not very thick, but very distinct. 
The intercostal spaces are wide on account of the coste being separated by a portion 
of the wall, which is very visible at the bottom of the spaces. 
There are no dimpled markings on this portion of the wall. 
There are very decided markings on the sides of the cost produced by rudimentary 
exotheca. 
The wall is thin. 
The calice is circular in outline. 
The septa are thin, delicate, unequal, rather ragged, granular, and slightly enlarged 
near the columella. There are three perfect cycles of septa and six systems. 
The numbers of the septa and coste are the same. 
The columella is not yery projecting above the base of the calicular fossa, and is rather 
elongated and ovoid. | 
The height of the corallum is 3ths inch, and the diameter of the calice nearly th inch. 
This species is more closely allied to the rare Turbinolia firma, Edwards and Haime, 
than to any of the other members of the genus. ‘The broad intercostal spaces and the 
inarkings on the sides of the coste in the new species distinguish it from Turécnoha 
jirma.
