Paratvpe : CAS 55406 (SU 44, 164), nearly complete left counteipart (pi. 14, fig. 2). 
Remarks : David (1943:18) noted that fA acutillus is probably the same species as f& edwardsi. Because she 
never included f S. acutillus in the synonymy of f S. edwardsi , we continue to recognize it as a sepa¬ 
rate species. The LACM specimen database lists LACM 1345 as a paratype of f& acutillus from 
LACM locality 1033. We know of no publication to support this assignment
