 Fossiles des Gres Siluriens de Saint-Germain-sur-IUe, La Bouexiere,

 Germ ain-sur-Ilie, &c.] Pp. 8. 8vo. Qiiimper. 

 The sandstones of St. Germain, sometimes believed to be Devonian, 

 contain Graptolites {Diplograptus &c.), and are L. Silurian. Amongst 

 the other fossils a large proportion are known to occur in the sand- 

 stones of May (Calvados), and some also are identical with forms from 

 the pebble-beds of Budleigh Salterton (Devon) and from the sand- 

 stones of Gorran Haven (Cornwall). The following new species are 

 described, but not figured : — Calymene Bayani^ Orthoceras subfractiim, 

 Lyrodesma Dufeti^ and L. securis. The new genus Pseudarca, allied 

 to Cucullella, is founded for the reception of a single species, P. typa.

It is found that most of the Cephalopoda are restricted to single beds, 

 only very few being common to diiferent beds. A detailed table of 

 distribution in time of all the Kutch Jurassic Cephalopoda is given in 

 pp. 215-224. E. T. N.
