This Sub-order is very poorly represented in British Eocene 
rocks, and in the Fareham Beds only three definable species have 
been brought to light, or at least to my knowledge, up to date : 
1. Horn era ramosa. d'Orbigny. 
2. Lichenopora sp. (Mediterranea ? Blainv.) 
3. Ditaxia variabilis, d'Orb.

*[Xote. — In my former list of Eocene Polyzoa (Proc. Yorksh. Geol. Soc., 
vol. xi., p. 158), I recorded " Diachoris intermedia, Hincks." In justice to 
Mr. A. W. Waters I append the following remarks, extracted from a letter to 
me, by way of explanation : " I notice that you give my D. intermedia as the 
same as Hincks, which is not the case. I first noticed the cast of Diachoris 
from the Bournemouth Beds, but from a cast in clay it is impossible to make 
a good species. I said something to the effect that if further specimens 
should be discovered, and better ones show that it is new, it might be called 
D. intermedia. You will find my remarks as a note to Starkee Gardiner's paper 
on the Bournemouth Beds in the Quart. Jour, of the Geol. Soc. " With this 
explanation it will be far wiser to retain the name in the list, in the hope that 
something better may be brought to light. ]
