CORALS FROM THE GAULT. 69 
bent m two; from 7. Boissyana, T. Patula,' 
pedicellated, and not adherent im the adult state; from 7. crregularis, T. corniculum, 
T. Fawasii, T. Gervullix, and T. uricornis,s by bemg strongly compressed quite down to 
the basis: and from 7. Saltzburgiensis, T. cuneolus, T. compressa, T. complanata, 
T. Basochesii, and T. tuberosa, by the existence of the above-mentioned four deep mural 
furrows. By their general form, all these corals much resemble many species belonging 
to the division of Cyathininz, but differ from them, and from all other Turbinolide, by 
T. cernua, md T. crassa,’ by bemg sub- 
having interseptal dissepiments. 
This fossil was found in the Gault at Folkstone, by Mr. Bowerbank. 
The LirHopENDRON GRACILE, Goldfuss,* is mentioned by Mr. Morris’ as having been 
found in the Gault of Kent, but as yet we have not met with any specimens of that species 
in any of the British palzeontological collections.

2 We here designate, under the name of Trochosmilia crassa, the fossil described by M. Michelin under 
the name of Turbinolia cernua, Goldfuss, and by ourselves as Trochosmilia cernua ; for, on comparing it with 
the specimens previously described by Goldfuss under the name of Turbinolia cernua, we have ascertained 
that they are not specifically identical. 
The species which must retain the name first applied by Goldfuss presents the following characters : 
Corallum pedicellated and strongly compressed quite from the basis. Coste thin, alternately unequal ; 
the larger ones rather prominent and somewhat lamellar. alice arched and elongated in the proportion 
of 100: 230. Septa thin, very closely set, and presenting on their lateral surfaces a great number of 
granulations arranged somewhat regularly in convex lines parallel to the upper edge. Forty-eight principal 
septa, separated by an equal number of small ones; some indications of an additional rudimentary cyclum. 
Height of the corallum, one inch and a half; long diameter of the calice, twelve lines ; short axis, five lines. 
(The figure given by Goldfuss, tab. xv, fig. 8, is not quite accurate.)
