Describes the new species Ortlioidea Hasina and Straj^arolus 

 (Euomj>halus) Metensis, from the zone of Ammonites margaritatus and 

 Belemnites clavatus, and from beds a little lower a new Ammonite 

 (A. Terquemi). The characters, synonymy, and history of Aulacoceras 

 (Orthoceras) elongatum are discussed ; and the fossil is shown to belong 

 to the Belemnitidce. A note is added on the problematical Tisoa

The first four parts deal with the Ajiorrliaidce of the' Gault and the 

 so-called U. Greensand of Rlackdown. The new species described are 

 Aparrhais Griffitlisii, A. Mantelli, A. Parhinsoni, var. Cunningtoni,A. 

 JiistocJiila^ A. oligochila^ and A. pachysoma ', and ' descriptions of a 

 number of previously recorded Ih-itish forms are given. The concluding 

 part treats chiefly of forms occurring in the Neocomian and Grey Chalk. 

 The genus Bimorjdwsoma is proposed and defined, and the following 

 new species belonging to it are described : — D. hinclispira^ J), ancy-
