MISS G. K. WATNEY AND MISS E. G.WELCH ON THE [Alay I9II, 



As Cyrtograptus linnarssoni is found only in association with 

 0. rigidus at Cautley, we have correlated our Rigidus Zone with 

 the zones of C. linnarssoni and C. rigidus of Builth. 



The assemblage of forms below the Q.-rigidus Zone do not 

 justify the interpolation of another zone in Cautley between this 

 and Monograptus riccartonensis. We have recognized four zones 

 only (see Table V, p. 233).

 and the Welsh Borderland, and in those or Cautley and
