This correlation is based on the following associafciou, common to the 

 Kate and Holmpatrick beds, and not found elsewhere in the sequence : — 



Diphyphyllum suhibicinum, common.

Syringopora cf. ramulosa. 



The commonest braehiopod species in the Holmpatrick beds are Chonetes 

 cf. papiUonacea, Produdus corrugato-hemisphericus and Sc/iizophoria resiipinata. 

 The Kate Eocks are full of very fragmentary remains of these three genera, 

 which agree very well with the Holmpatrick species.
