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 witli 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 (PI. 7, fig. 1 g, h) agree for 

 the most part with the first-named form.
