Three specimens in the Biological Survey collection come from 

 Santa Anita (U. S. N. M. Nos. 37683-5). This species has been excel- 

 lently characterized by Van Denburgh (1898, p. 65). In addition to the 

 characters employed by him, it may be noted that the limbs are much 

 weaker and the body and tail more elongate than in G. scincicauda webbii. 

 The proportions of arm and leg to body length in two specimens of each 

 species are as follows : 



G. multi-carinatus G. s. webbii 

 Arm/Body Length .19, .23 .25, .27 



Leg/Body Length .27, .29 .35, .36
