Wing-like lateral expansion of carapace less pronounced, separated by more or less symmetrical concavity, with anterior and posterior teeth subequal in structure ( Fig. 3 A–C). Pararostral teeth elongated, reaching beyond level of distal ends of preorbital lobes ( Fig. 7A )....................................................................... S. foliatus Ward, 1936 -. Wing-like lateral expansion of carapace more pronounced, separated by asymmetrical concavity, with anterior lobes wider than posterior one. Pararostral teeth short, not reaching level of distal ends of preorbital lobes........................ 2 2. Concavity of lateral expansion of carapace relatively deep; anterior, posterior lobes of lateral expansion triangular....................................................................................... S. sublimis ( Rathbun, 1916 ) -. Concavity of lateral expansion of carapace relatively shallow; anterior lobe broadly triangular, posterior one tapering to sharp point............................................................................ S. cristatus ( Balss, 1924 )
