preference, where it can back up and secure rear protection." 

 In several months' stay in the region where it occurs he never 

 met with one of these animals, though he was taken to their 

 haunts by the natives, who use dogs to trail it. 



Because of its large size the pacarana is sought out by 

 natives for food, while its lethargic manners and inoffensiveness 

 make it easily vulnerable to its enemies. In habits it is likely 

 to prove largely nocturnal, but captives seem to be active by 

 day as well. Unless in some way given protection it is likely 

 to be exterminated in the limited area where it occurs. A 

 similar fate at the hands of the natives very likely in former 

 days overtook its West Indian relatives, Elasmodontomys and 

 Amblyrhiza.

The nomenclature of the chinchilla has been much confused 

 owing to the fact that the naturalists of over a century ago 

 believed that Molina's description of his Mus laniger applied 

 to it. In 1830 Lichtenstein pointed out that Molina's animal
