Remarks. 
The Zaphrentis ambigua beds of Lane 
are certainly below D,, but may extend 
zonally a little lower than D,. (The 
massif of Colne, Lanes,j is probably of 
the same age.) 
The megastoma-Beds of Rush may be 
of the same or earlier age than the Lane 
conglomerate. 
The suggested horizon of the famous 
St. Doulagh’s Quarries is deduced from 
the practical identity of their fauna with 
that of ‘the Waulsortian’ of Co, Olare 
described by J. A. Douglas.
