Figs. I, 2, 3 An uncrushed carapace extracted from a pyritous 

 nodule and showing the normal convexity. Natural size. 



Figs. 4-1 1 Flattened carapaces, all enlarged to 2 diameters and 

 showing various structural features. Attention is directed especially 

 to the indications of frontal or ocular nodes, to the rostral spine and 

 the two lateral frontal spines and to the postmedian ridge which is 

 usually, for some reason, hardened and sometimes distorted.
