 Wood, fibrous, hard, heavy, brown. — Spongise or Siphoniae 

 of different forms. — Millepora — Lunulites {Lam.) Re- 

 tepora ?^Galerifes subuculus {Lam.) — Cidaris papillata, 

 plate and spines. — Crinoidal Column. — Pecten asper, 

 P. quinquecostatus {So'w.) P. with large rough ribs. — 

 DianchorastJ-iata {Sow.) — Plagiostoma like P. duplicatum. 

 — Crassatella? — Ostrea. — Inoceramus. — Teredo ? — 

 Chama or Gryphsea ? — Terebratula pectinata, and 

 two plaited species described by Smith from the green- 

 sand of Wilts ; also a smooth species. — Magas pumilus. 

 — Balanus, large valve of the operculum. — Ammonites 

 complanatus {Mantell). — Nautilus elegans {MantelP, a 

 very large and fine specimen. — Sharks teeth. 

 Some of these blocks contain nodules of pale gray chert.
