In the family Porinide, as described by Mr. Hincks, ‘ Brit. Marine 
Polyzoa,’ four genera were included, viz. :— 
1. Genus Porina, D’ Orb. 
2. ,, Anarthropora (part), Smvitt. 
3. 4, Lagenipora, Hincks. 
4 »» Celleporella, Gray. 
Tn the classification of Mr. Busk only two of these four types are 
accounted for, and in justice to Mr. Hincks I have allowed species of 
these genera to precede the Tubucellariade, not as a part of Mr. Busk’s 
grouping, but because they are not otherwise accounted for. Miss E. C. 
Jelly informs me that Lagenipora is far more widely distributed in 
British seas than was supposed when the original description was drawn 
up; and in some of his foreign Cheilostomata Mr. Hincks describes a 
new species of the same genus.
