On the Oolitic Echinodermata op the Neighbourhood oe 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 our 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 jlorigemma, Phillips. In the same quarry with the following (opposite 

 the play-ground belonging to Cowley School), where I have found the test : 

 the spines are profusely common everywhere in the Coralline Oolite.
