Batopora and its Allies. 87 
Canu* united Stichoporina reussi, Stol., and Batopora 
multiradiata, Reuss, but it does not now seem that this can 
be maintained. 
The North Italian specimens of simplex are 5°8 mm. 
diameter with the dome very little raised. Kirkpatrick’s 
are 20 mm. and Calvet’s have a more elevated cone, but 
I do not think that they should be separated on these 
grounds.
