CORALS FROM THE GREAT OOLITE. Ill 



2. MoNTLivALTiA Waterhousei. Tab. XXVII, figs. 7, 7 a. 



Corallum straight, erect, cylindroid, and convex at the basis, where no appearance of 

 adherence is perceptible. Epitheca very strong. Calice circular, or nearly so ; fossula 

 well defined and somewhat oblong. Sejjta rather thin, unequal in size alternately, and in 

 general sixty- six in number ; sometimes an equal number of rudimentary ones situated 

 between the former. Many of the septa appear to have their upper edge somewhat arched 

 towards the centre of the calice. Height one inch and a half; diameter one inch two lines. 



This fossil was found in the OoUte of Minchinhampton, and belongs to the palseonto- 

 logical collection of the British Museum. 



M. D'Orbigny has given the name of MontlivaUia regidarii^ to a coral found in the 

 Kelloway Rocks, in France, which very much resembles this fossil by its general form, but 

 has its epitheca more strongly wrinkled : none of the known specimens show the calice, 

 and we are, therefore, unable to decide whether it be or not a distinct species. This form 

 is not seen in any other species of the genus MontlivaUia, but we must remark that if 

 M. LabecJii^ became taller it would become, in that respect, very like M. Waterhousei, 

 and that some ill-preserved specimens of M. reyidaris, belonging to the collection of 

 M. Hebert, of Paris, are almost as short as the former. M. Labechii differs from 

 M. Waterhousei by its septa being more numerous and terminated by a straight edge 

 inwardly.
