An introduction on the influence of descent in derivation of new 

 forms, and as ground of classification here followed. Four forms of 

 Ammonites appear in the Trias ; and under the groups 1. Arcestidce, 

 2. Lytoceratidm, 3. Trachyceratidce, 4. jEgoceratidce^ all the forms 

 subsequently derived are classified ; 33 genera are enumerated. Divi- 

 sion 3 is exclusively Triassic. Div. 1 includes 2 subgenera, one of 

 which, Scldcenhachia, is new, and includes the Cristati. Div. 2 includes 

 Hamites, &c. Under Div. 4 is a new genus Olcostej)hanus, including 

 A. Asterianus, &c., as is Hoplites^ to include A. angulicostatus, rhotoma- 

 yetisis, &c. Stoliczkaia, n. gen., confined to India, S. tetrayona and 

 clavigera being new names for species originally referred by Stoliczka 

 to A. disjjar. A list of all the Cretaceous species in each genus is 

 given. E. B. T.

Apparently much the same as the above. Forms the new genus 



Accmthoceras, besides those mentioned above, and 4 families as above, 



except that Tropitidce takes the place of Trachyceratidce.
