PLATE XX. 



Stellaster Sharp] I, Wright. 



From the Inferior Oolite. 



This grand Jurassic Goniaster was obtained from the Inferior OoHte near North- 

 ampton by my old esteemed friend Samuel Sharp, Esq., F.G.S., in whose collection it 

 was contained when I figured the specimen. It now forms part of the Jurassic Echino- 

 dermata collection from the Inferior Oolite of Northamptonshire in the British Museum.
