Type 
The measur einents indicate considerable variation in form, 
especially in the amount of compression of the calice. 
Synapticula are very abundant between the costae near the 
base, and they are quite abundant near the margin of the calice. 
In the intermediate area the wall is almost or entirely solid. 
The costae are not prominent , are relatively wide, the inter- 
costal furrows narrow, every other or every fourth one more 
prominent .
