Middle or Late Miocene (Mandra 1963, Hart, 1966; Durham 1974), near San Miguel (actually closer to 
the town of Bradley), Monterey County. 
Referred Specimen : From the type locality: SU 775, whereabouts unknown. 
Remarks : David (1943) suggested that tE. michaelis is cogeneric with f Ganoessus Jordan 1920b. Grande 
(1985) offered no opinion on this issue, thus we follow David as the last reviser and recognize f Ganoessus 
michaelis as the valid species name. According to David (1943:95) the holotype is lost, but it is in the CAS 
collection.
