Zygobeyrichia nov. gen. Genotype Z. dei'onica Jones and Woodward, 1889. The 

 new generic name is proposed for a group of large Beyrichidae that seems to represent 

 a departure from the type from the Silurian stock. 



Zygobeyrichia apicalis nov. and Z. extrema nov. This is distinguished from Z. apualis 

 by its shorter and more gibbous form ; and from species of Kloedenia it differs by the 

 complete loss of the posterior lobe, the greater depth and length of the sulcus and the 

 ventral prolongation, etc.
