P. briareus, Mill., P. subangularis, Mill., and P. sealaris, Goldf., 
by the absence of lateral branches from the rays, and from all 
others of its Liasic congeners with which we are acquainted in 
the strength and thickness of the rays themselves. 
Locality and stratigraphical range.—This remarkable Sea Lily 
was discovered by Mr. R. E. Gavey, C.E., in the Lower Lias of 
Mickleton Tunnel near Chipping Campden, Gloucestershire ; it 
is imbedded in shale resting on a hard slab of limestone, and was 
associated with the remains of other Radiata. 
We dedicate this fine Liasic Crinoid to the memory of the late 
Prof. Goldfuss, whose great work, ‘ Petrefacta Germaniz,’ has so 
much increased our knowledge of the Liasic and Oolitic fauna.
