212 R. F. Tomes—On Heterastrea, Lower Lias. 
to have given rise to a smaller calice within the larger one, which has 
a considerable degree of prominence, and bears an extremely close 
resemblance to some of the corallites represented in the upper part 
of Laube’s figure of Elysastrea Fischeri. 
I have met with two ill-preserved specimens of a coral which 
resembles this species in the size and openness of the calices, the 
one from a gravel-pit at Charlton, near Evesham, and the other from 
the zone of Ammonites angulatus, near the village of Church Lench, 
a few miles north-west of Evesham.

By the kindness of my friend the Rev. P. B. Brodie, the type- 
specimen of this species is now before me. The calices, which are 
in process of division, or have already undergone that operation, are 
conspicuous over the whole upper surface of the corallum, but gem- 
mation, though apparent and marginal, is not frequent; nor is it 
common, though well marked, in other specimens of this species in 
my collection. 
It is a distinct species, and in some examples the specific characters 
are even more typically developed than in the type itself. They are 
all more or less flabelliform, but they present every degree of 
inclination from a nearly vertical to a horizontal position. ‘The 
finest specimen yet met with has the form of a regularly oval 
plate, ten inches long, and not more than an inch in thickness. It 
was attached by a broad space near one end of the under side, 
which is flat. The calicular surface is horizontal. Fissiparity 
occurs over the whole of the latter part, but gemmation is by no 
means common, though, where it appears, it is unmistakeable. This 
specimen was taken from a quarry near to Prior’s Cleeve, about five 
miles north-east of Evesham, and its place in the Liassic beds will 
be best explained by the following section :—

I have also obtained the present species from Binton, about four

with Ammonites angulatus.
