Solenocheilus Cf. collectus Hyatt.
Stearoceras gibbosum Hyatt? Perhaps a young specimen of this species, though it will probably prove to be different. The cast preserves a fine line down the center of the ventral surface which disappears before reaching the deep sinus. The sinus is somewhat shallower than that figured by Hyatt, and it may be an Endolobus.
Griffithides scitula (Meek and Worthen) Vogdes.
28. Burlingame Shales. Olive shales, generally very argillaceous, though arenaceous in streaks, and in places even contain sandstone. These shales are 120 feet or more in thickness, and for the most part are not fossiliferous, though in places fossils are very abundant. In the upper part is the Dover-Silver Lake coal, and above it usually a layer of impure limestone.
