HEMIPEDINA JARDINI, Wright. 
A specimen of this species from the Marlstone (spznadz 
hemera) of Alderton Hill, is in the collection of Mr 
Richardson. 
STOMECHINUS aff. INTERMEDIUS (Agassiz). 
A portion of the test of a large Scomechznus from the 
Cephalopod-Bed of Sodbury, near Bristol, appears to 
belong to an echinoid closely related to Stomechinus 
intermedius (Agassiz). As far as can be seen from the 
specimen, which consists of part of an interambulacrum 
from immediately above the ambitus, and portions of the 
ambulacra on either side, the test seems to have a more 
granular character. Both in the ambulacra and inter- 
ambulacra, the granules and secondary tubercules are 
rather smaller than in S. zz¢exrmedzus, are more closely 
packed, and extend right up to the sutures.
