CIDARIS cf. YEOVILENSIS Wright. 



In the same bed as the plates of Cidaris houchardi Wr. 

 at the old quarry with the lime-kiln in it to the east of Loder's 

 Cross, near Bridport, are numerous examples of club-shaped 

 radioles. They do not appear to belong to Cidaris houchardi, 

 for in the British Museum pieces of the radioles of that species 

 are seen to be long and narrow : they are nearest to that 

 figured by Wright as Cidaris yeovilensis,^ but more spherical. 



CLYPEUS AGASSIZI Wright. 



This species has been found to occur along with Clypeus 

 alius M'Coy in the Garantiana-^eds of the Castle-Cary district 

 and Woolston, and in the Top-Beds of places further south.

 Beds, Mill Pitch, between Hadspen and Cole, near Castle Cary. 



CLYPEUS ALTUS M'Coy. 



In our main paper, on page 163, it was stated that 



" Clv/iem; agassizi is found associated with Clypeus alius around 

 Castle Cary, Bruton and Crewkerne. Towards the south it appears 

 to give place entirely to Clypeus alius." 



and on page 166, Clypeus alius 



" Occurs chiefly in beds of ■post-garantiance date in Dorset." 



These remarks were mainly based upon the information 

 published by the Geological Survey. 



We are now able to add that at Mill Pitch, between 

 Hadspen and Cole, Clyfeus agassizi occurs not uncommonly 

 in the basal portion of the deposit of garantiance hemera along 

 with Clypeus alius ; that Clypeus alhis is fairly abundant 

 in the Garantiana-Beds of Hadspen and Woolston, and occurs 

 — along with Clypeus agassizi — in the Top-Beds of further 

 south.
