Figure 1. The apertural portion of a cup showing the marginal fringe. 



Figure 2. A large, obliquely compressed cup exhibiting about one-half of the 

 apertural margin and its spicular fringe. In both of these specimens 

 it is seen that there is a difference in the strength of the spicules 

 composing the fringe, the coarser seeming to lie in the line of the 

 coarser vertical bundles of the reticulum.
