Remarks. — This form, to which it is proposed to restrict 

 the name Rhynchonella cheltensis is readily distinguished from 

 the true Rhyn. subdecorata Davidson. It is that figured by 

 Davidson, with a query, as " Rhynchonella subdecorata, var. ? ", 

 in the supplement to that portion of his monograph which 

 deals witli the Oolitic and Liassic Brachiopoda. Da^•idson's 

 fossil is a little more circular in outline than the majority 

 of our specimens, which exhibit a distinct tendency to expand 

 transversely. 



Specimens liave been obtained from the Scissum-Bed% 

 of Stanley, Nottingham and Cleeve Hills, near Cheltenham ; 

 Cassey Compton, near Chedworth ; Withington ; Puckham, 

 near Cheltenham ; and an opening in the bank on the north 

 side of the road near Cornwell, near Chipping Norton.'
