and ultimate segment longer, and in having a more convex carapace. 
The front varies in the curvature of both inner orbital lobes and 
frontal lobes. 
Edmondson (1951, fig. 24b; 1954, fig. 32a) does not show the 
conspicuous frontal ridges which are clearly visible in Rathbun’s 
(1906) plate 12, figure 1. In his figures he shows what appears to be 
a ridge which continues behind the orbit; in the present specimens 
this is a groove, not a ridge.
