The fossils found in (2) and not in (1) are Stephodonta demissa, Spirifer zigzag, Atropa reticularis and A. spmea Crimoid, short and abrupt Spirifer mediae. Otherwise all the fossils of (1) also seem to occur in (2). To the restricted species of (2) should be added Cyptiphyllum and Heliophyllum and Amplexus. Ambroelin is particularly abundant in these beds. The only known restricted species to join (1) is Stephalozia truncata. Dr. Pohlman thinks there are too many species of Eurypturids and is convinced that Whitfield scorpion is nothing but the Euracarus scorpionis. He says that nothing has been done towards working out the mouth and limb structure since Hall's time. In the afternoon visited Bennett quarries where in 1 foot can be seen the Batulines, Grandops and Cornifrons.
