strongly exsert and project considerably above the spaces between 

 them. They average seven millimetres in diameter, and are separated 

 by depressed spaces which in some places are wider than the calices 

 themselves and in others narrower. Externally, the resemblance of 

 the specimen to P Woodmani is not inconsiderable. Transvei-se and 

 longitudinal sections of both, however, show that the Peace River coral 

 differs from P. Woodmani in that its corallites have no definite walls 

 and no central tabulate area, as those of P- Woodmani have, and in its. 

 non-confluent costse and septa which extend almost to the centre.
