As already stated, Mr. Busk, in the third part of the British 
Museum Catalogue, agreed with Professor Smitt in his critical 
suggestions, but he failed to modify, to any great extent, the synop- 
tical arrangement of the Cyclostomata, as adopted for the Crag 
Monograph. Very wisely, the Family of the Diastoporida? is broken 
up, and limited to two Genera — Di'istopora and Mesenteripora — and 
another family founded for the reception of a peculiar group of 
Polyzoa, which occur both Recent and Fossil. The name of the 
typical genus, Di^cnpurella, is the type of the Family Discoporellidse, 
and the included genera are — 
Discoporella, Gray. 
Radiopora, D'Orbigny. 
Domopora, D'Orbigny ; and 
Defrancia, D'Orbigny. 
And the Frondiporidae of the Crag, is changed to the Fasciculinae of 
the British Museum Catalogue. As a matter of course, the Families
