Spatangus purpureas* Mull. Cor. Crag, Sutton, Orford, 
Aldborough, Walton Naze passage beds, Pliocene clays 
St. Ertb, Middle and Upper Bed Crag, Chillesford 
beds, pleistocene, Selsey, Gourock, and Largo Bay 
Fifeshire. Dr. Gray made one of the larger 
Spatangoids a new species, S. regina. Of this several 
fine specimens are known fossils, one from the Cor. 
Crag, Ipswich Museum (no loc.), and another from 
Sutton, now in the Brit. Mus., are very characteristic 
examples. This last, I think, comes from that portion 
of the Coralline Crag Hill, of Prestwich, referred to 
in “ The English Crags,” A. and R. Bell, as a “ face 
of very hard indurated Coralline Crag, highly 
coloured, and cemented by an infiltration of iron. 
This contains large Echini , Spatangus for the most 
part.” The form appears to be a question of size 
more than specific difference, inhabiting warmer seas 
than those of the later pliocene period.

It also obtains in the early pleistocenes of Bridlington, 
Kilchattan in Bute, and in the raised estuarine 
laminarian clays at Magheramorne, Lough Larne. 
The Starfishes are seldom well preserved, as in addition to 
the habit many have of breaking up ; the matrix in which they 
are contained is seldom so favourable for conservation as are 
the Arctic clays of Montrose containing Ophiolepis gracilis.
