REPTIL1A*-LIZARD. 697 



" The alligator, when after prey in the water, or at its edge, swims so 

 slowly towards it, as not to ruffle the water. It approaches the object side-

 the scales, gild them with undulating reflections. The upper parts of the

 side of the neck, formed by a transverse row of \a.xv;e scales, separated from those of the 

 belly by very small ones ; bone of the cranium projected on the temples and orbits.
