1 There are indications of a JVerincsa-bed in the Upper Freestones, which may be on the horizon 

 of the bed, p, near Birdlip (see postea, p. 66). On the whole there are three distinct beds containing 

 Nerincea in the Marl and Freestone Series, though these beds cannot be made out at every point 

 between Stroud and Cheltenham. These three beds constitute the Middle or Second Nerinssan 

 horizon.
