text: The great mass of the strata in question clearly belongs to the "Lima-beds or Zone of Ammonites Bucklandi." This is proved by the remarkable abundance of Gryphœa arcuata of the typical form, and by the numerous and fine examples of Lima gigantea which occur—and especially by the presence of such characteristic arietiform Ammonites as A. Bucklandi, Sow., A. Conybeari, Sow., A. Kridion, Hehl, and many others.
