No. 209. [505, Cast]. Ammonites Jason, Reiuccke, This beautiful species belongs to the group "Ornati" of Von Buch. The specimens from the Oxford Clay of Christian IVIalford, England, where this was found, are compressed in the marl, but show well two lateral shelly processes developed on each side of the aperture. This feature is found in the young of many species of Ammonites, but is lost on their attaining the adult form. Ward Collection, University of Rochester. No. 210. Ammonites Lamberti, Sow. From the Oxford Clay (Oolite), Weymouth, England. No. 211. Ammonites laticostatus, Sow. This is most probably identical with A. cnprlcornus of Schlotheim, and is very typical of the group "; In its adult stage, this species loses its characteristic form, and assumes one somewhat resembling A. Bticlui, Sow. In this state it has received various synonyms, but it is best known as A heterogenus.
