On the Oolitic Echixodermata of the Neighbourhood of Oxford. — 
As our knowledge of the geographical distribution of the Oolitic Echinodermata 
is very imperfect, the following list of species collected by myself and others 
in the neighbourhood of Oxford may not be unacceptable, as tending, though 
but in a small degree, to add to oui' stock of information on this point. 
Cidaris Smithii, Wright. With the jaws preserved, in the Coralline Oolite, 
Bullingdon, where the spines are also occasionally found. 
Cidaris florigemma, Phillips. In the same quarry with the following (opposite 
the play-ground belongmg to Cowley School), where I have found the test : 
the spines are profusely common everywhere in the Coralline Oolite. 
Cidaris Bradfordensis, Wright; Plates and perfect spines occur in the Islip 
Cornbrash.
