being as broad as they are long with bases circularly rounded and broad necks under 
the apices, densely and finely denticulated (8—14 denticles on each side) and with 
a broadly rounded central cusp. Specimens of this type agree in sculpture with var. 
grandis and striata. In the second type the rhachian teeth are usually more elon- 
gated, with their sides irregularly rounded, a comparatively narrow neck, stronger 
and fewer denticles (5—7 on each side) and an acute or subacute central cusp. These 
belong to the type; the teeth of forma multilirata (Pl. 7, fig. I g, h) agree for 
the most part with the first-named form.
