854 G. RK. VINE ON CRETACEOUS LICHENOPORIDE. 
column about half a line; breadth of capitulum, so far as at present 
known, varying from three quarters of a line to a line. Basal 
attachment or early mode of growth unknown. Zoecia arranged 
in serial rays; but the cells rarely exceed two in each ray, depressed 
in the central portion of the zoarium, slightly exserted towards the 
margin, orifices oval or circular, peristome thick. Ozcia unknown. 
No cancellous centre or interspaces. 
Horizon: Neocomian. 
Locality unknown. 
The specimens of LZ. paucipora which I have here described have 
been handed over to me by Mr. George Busk, F.L.S. He informs 
me that they were discovered by Prof. P. Martin Duncan, F.R.S., 
amongst other fossils from the Greensand of some unknown 
locality. 
It appears to me to be pretty evident, from the peculiarities of 
the marginal cells in the full-sized capitulum already figured, that the 
zoarium of this species may yet be found to grow much larger than 
in the specimens submitted to me for examination. The transverse 
section of the capitulum, and also the longitudinal section of the 
column, are unique in character, and in all probability we have here 
the colonial beginning of some unknown type of Mesozoic Polyzoa, 
rather than a matured species ; nevertheless it will be better to allow 
the form to bear the name given to it.
