This peculiar species, was represented by several specimens in 
Mr. Jesson's original collection, but specimens were sent by him to 
Prof. Duncan for identification, as Mr, Jesson supposed them to be 
allied to the Corals, if not new types of the group. Prof. Duncan 
handed them over to Mr. George Busk and ultimately the specimens 
passed from his cabinet to mine. When I described the forms I was 
entirely ignorant of the locality whence tkey were derived. After 
the publication of my paper Mr. Jesson wrote me respecting the 
specimens, &c. When sketching out my original description I knew 
of no group, recent or Fossil, in which they could be placed, except 
among the Lichenoporidos, and as only two Genera are given by 
Mr. Hincks — Lichenopora and Domopora, I prefered to present it as 
a member of the first, rather than of the second genus. After the 
publication of my notes Mr. A. W. Waters expressed to me his 
doubts respecting the placement of the form amongst ordinary 
Lichenopora^ and out of deference to him I have placed (?) after the 
generic term. It is very evident that the specimen described is 
remarkable, both on account of its peculiar stipitate column and 
disk-like capitulum, and I have not been able to find in the writings 
or figures of Goldfuss, Hagenow, Roemer or Novak any indications 
of forms similar in character, either among the Greensand or Upper 
Chalk Polyzoa.

There are a few specimens of a species of Lichenopora^ of the 
Discoporella type in the Jesson collection, but these are more like 
Busk's figure than Hincks'.
