rhomhifer and P. depressus. Others are recorded from the 

 Miocene of ffiningen and the Lignites of Bonn-on-the-Rhine, and 

 are exhibited in this case. 



Sub-order 2. — Lacertilia (Lizards). 



The earliest known member of the large group of existing 

 Lacertian reptiles is Macellodus (with which Saurillns is pro- 

 bably identical, or closely allied), mostly known by jaws and teeth 

 from the Piirbeck beds of Swauage, Dorset, a small lizard with 

 pleurodont dentition, dermal scutes, and proccelous vertebrae. 



Coniasanrus, with expanded teeth, occurs in the Chalk of 

 Kent and Sussex. Several genera of lizards are represented in 

 the Tertiaries of France and America. Remains of a species of 

 Iguana occur in the Eocene Phosphorites of France, and the 

 Middle Eocene of Hordwell, Hampshire.

The Anguiditi (Slow-worms) are represented by several 

 genera from Gers in France (Middle Miocene), and from Rott, 

 near Bonn (Lower Miocene); from Steinheim, Bavaria; and 

 from Eno-land and North America.
