No. 85. [354] Teleosaurus minimus, Quenst. 



Skull (cast). This relic of the smallest Teleosaurus yet described, shows 

 well the orbital sockets and the nasal fossae. It is from the Lias of Wurtem- 

 \>evg, and is now in the University Museum of Munich. Size, 6x4. 



No. 86. [259] Leptorhynchus giganteus, Falc. and c;aut. 



Muzzle (cast). This fossil 



was found in the Sewalik 



Hills, India (Pliocene), and 



is in the British Museum. 



Size, 2 ft. 6 in. x 11 in. 



No. 87. [271] Belodon (Phytosaurus) Kapffli, Meyer. 



Skull and Lower Jaw 

 (cast). This genus, with 

 Steganolepis, were the ear- 

 liest representatives of the 

 order. This species had a 

 long, slender muzzle, like 

 the Gavial, and long, con- 

 ical, curved teeth, which plainly point to a carnivorous nature. This skull 

 was discovered in the Keuper sandstone (Upper Trias) at Stuttgardt, Wurtem- 

 berg, and is in the Royal Museum of that city. The lower jaw is in the 

 British Museum. Size, 2 ft. 6 in. x 13 in. 



ORDER LACERTILIA. 



The lizards may be described as having bodies elongated, and 

 terminated with a tail ; the legs usually developed and always 

 with a pectoral arch ; the vertebrae procoelus (rarely amphicoelus), 

 not more than two sacral ones, and ribs single headed ; the 

 madibles united in front, quadrate bone articulating with skull, 

 and teeth in grooves ; two nostrils, and usually movable eyelids. 

 The skin is covered with horny scales or tubercles (sometimes 

 bony). 



Formerly the order was grouped with the crocodiles as the 

 Sauria. Some twenty families and toward one thousand species 

 are now recognized, chiefly belonging to the tropics. 



The LaceHilia appear in Europe certainly as early as the 

 Jurassic. None have been found in American Cretaceous, but 

 they are abundant in the Eocene lake-beds, some of large size, 

 and some, like the Glyptosauridae, being mailed with ornamented 

 plates of bone. In IVTiocene and Pliocene they are rare.
