Bunaia woodwardi 



Fig. I A weathered exterior of a head shield showing the tri- 

 angular central area or " glabella " and the five pairs of lateral lobes 

 crenulating the surface and corresponding to the legs beneath, x 8 



Fig. 2 The interior of a head shield with five pairs of radial appen- 

 dages and evidently a 6th pair at the central mouth. The light 

 colored lines on the right hand radial areas are elevated linear ridges 

 which appear to be parts of the appendages themselves, and it is 

 thought that the broad dark areas may include both legs and gills, x 8 



Fig. 3 A crushed and defaced head shield with a postabdomen 

 of ridged segments, x 8 



Fig. 4 A telson spine which lies close to the specimen fig. i and 

 it is thought may belong to this species, x 8 



All the foregoing are from the Bertie waterlime (Silurian) at the 

 East Buffalo quarries. 



Bunodes lunula 

 Fig. s An exfoliated carapace from the Siluria,n of the Island of 

 Oesel, showing the broad dark bands left by the six pairs of cephalic 

 appendages and also the central divergent ridges which seem to be 

 the interior projections of the ridges of the " glabella." x 3
