the back of the head; width of the notch two-fifths the length of the head. Cheek 
and side of the lower jaw with five large black spots. Ventral shields in twelve series. 
Dorsal shields four. 
Hab. South America; Lake of Santa Cruz de la Sierra. 
3. JACARE MULTIScUTATA. (Brazilian Jacaré.) 
With sixteen series of ventral shields; hinder ventral shields very narrow. Dorsal 
shields in ten longitudinal series, five on each side. 
Hab. Brazil.

This is very like the following; but the head is rather broader, and the dorsal and 
ventral shields are much larger, and more numerous. 
It is known from the young of Jacare nigra by its olive colour, the spots on the sides 
of the jaws, and the presence of the distinct nuchal scutella. 
5. JACARE OCELLATA. (Eyed Jacaré.) (Plate XX XIII.) 
Dorsal scutella broad, uniformly keeled, in eight longitudinal series in the middle of 
the body; ventral scutella in twelve longitudinal series, the hinder ones smaller, longer, 
and more numerous; the central pair of cervical scutella in the first series smaller than 
those that follow.
