CAIMAN FUSCUS (Cope) 



The distinction of the Central American caiman, as Caiman fuscus 

 (Cope), from the Amazonian Caiman sclerops has been proposed 

 by myself in a recent paper." 



The skull of the Central American form is decidedly more massive, 

 with a relatively broader snout, and the palatines are inflated an- 

 teriorly. The pterygoid border of the palatine fenestra is longer than 

 in sclerops, and thus presents the extreme of divergence in this 

 character from the Paraguayan Caiman yacarc. 



In the Panama series listed below, the nuchal scutes are regularly 

 4-4-2-2 in number, but an additional pair of small scutes is frequently 

 intercalated between the nuchals and the dorsal shield. No. 54093 

 has the nuchal formula 2-4-2-2. The dorsal shield is composed of
