Quite similar to specimens obtained in Ecuador by G. Hammond, 

 submitted to Mr. Gerrit Miller, by whom they were pronounced to be 

 identical with H. ccistaneum^ and compared with the common H. 

 perspicillatum. 



The species is distinguished both by its smaller skull and by the 

 smaller size of the teeth, which are, however, remarkably variable, 

 scarcely any two of the specimens agreeing in all details of the 

 dentition.
