VINE: CAMBKIDGE GREENSAND. 
25 
Cambridge Greensand collection, but they are found both free, and 
adherent to foreign bodies. The species, wherever it may be 
ultimately placed, is the same as ordinary cretaceous forms — and 
identical with those found in the Upper Greensand of Warminster. 
The specimens are both large and small. 
Zoarium both encrusting and free — dome shape, with cells, 
radiating" from the centre, but the other characters, if present, are 
too indistinct for diagnostic purposes. 
Localities : Cambridge, Greensand. 
I do not think that the above species could be confounded with 
the Lunulites urceolatus Lamx., of Lonsdale. (Dixon's Geo. of Sussex, 
Tab. 1., figs. 8 a, 6, c.) Morris in his Catalogue of Brit. Fossils 
gives L. urceolata, and L. radiatas Mant., as synonyms, also Lonsdale 
quotes Goldfuss' fig. (Petrefac. Tab. 12, fig. 7,) and this Busk 
regards as a synonym of L. conica Defrance Var. a. depressa. (Crag, 
Polyzoa, p. 88.)

Test consisting- of a single more or less hemispherical, ovoidal, 
or pyriform chamber terminated in many cases by a short narrow 
open tubular prolongation, or a succession of such chambers in 
variable numbers, connected together in a moniIif(jrm series, varying 
in direction of growth, &c. 
As this genus is re-described by Mr. Sollas I have selected 
from his "General Characters" so much of his diagnosis as the 
specimens before me warranted. The forms are very abundant in
