ZOOLOGY. 631 



the Salamanders, and placed them as a distinct family 

 between the two former. By reason of their rudimental 

 feet they keep simply upon the earth and bore them- 

 selves passages therein. Their motion is serpent-like, 

 because they lie upon the belly and cannot assist them- 

 selves with the feet. 



Fam. 8. Crustacean Reptiles, Bream-like Schvp- 

 penecksen. 



Four perfect feet, body covered all round with small 

 granular scales, tongue short and hardly slit. 



Here belong the Flying Lizards, the Iguana? and 

 Basilisks. They usually climb about on trees and seek 

 for beetles and berries. 



Fam. 9. Ptilotoid Reptilia, Perch-like Schienenechsen. 



Four perfect feet, but plates upon the belly and tail, 

 tongue thin and bifid. Here belong the common Lizards 

 and the " Sauvegards" or Monitors. Their body is 

 usually depressed. They cannot climb, but run about 

 briskly upon the ground and eat beetles, and even the 

 higher animals. Many are a fathom in length. 



B. SARCOSE REPTILIA LARGE-EYED. 



3546. These animals have tubercles, spines and plates, 

 with four perfect feet, as in the higher Lizards, but the 

 toes are of pretty equal length; there are no palatal 

 teeth, and the tongue is not fissured. They are of varied 

 size, lead a sluggish and mostly nocturnal mode of life, 

 and have a slow pace, occurring too only in warm 

 climates. 



Order 4. Sarcose Reptiles. 



3547. Feet abnormal, being fin- and wing-shaped, 

 adapted for climbing or clinging. They correspond quite 

 closely to the three next animal classes. 



Fam. 10. Ichthyoid Reptilia, Herring-like Ich- 

 thyosauri. 



All four feet converted into fins. 

 Here belong clearly the monstrous extinct animals, 

 which formerly lived in the sea. They had gomphotic
