The other species has smooth spines, circular in cross- 
section, and tapering (text-figure I ¢.) 
The former species has been recorded from the J/ar- 
morea-Beds at Froud’s Quarry, Bedminster; and the 
latter from the Ostrea-Beds (pre-p/anorébzs) at Aust Cliff, 
near Bristol; and from the Zarmorea-Beds at Bedminster. 
A specimen from the last-named exhibits one or two 
incipient granulations about halfway up its length. 
CIDARIS EDWARDSI, Wright. 
A few slender spines obtained by Mr Richardson from 
beds of caprzcornus date in the railway-cutting at the 
western entrance to the Greet Tunnel, near Winchcombe, 
Gloucestershire, on the Cheltenham and Honeybourne 
Line, are probably referable to this species. The type of 
Czdarts Edwards: was found at the same horizon at 
Mickleton Tunnel, near Chipping Campden."

This appears to be the species the remains of which 
are so plentiful in the Os¢vea-Beds at the base of the 
Lower Lias. ; 
I have examined a slab from: the Ostvea-Beds of a 
section near Pirton Church, Worcestershire, on which 
were a large number of the finely-striated radioles, and 
one or two ambulacral and inter-ambulacral plates. 
Radioles and parts of the test have also been obtained 
from the Ostrea-Beds (prep/anorbzs), of two-and-a-half 
miles south-west of Evesham ; Bickmarsh, near Evesham ; 
Knowle, near Birmingham ; Sedbury Cliff, near Chepstow; 
and the base of the Os¢rea-Beds at Kilmersdon, near 
Radstock, Somerset.
