“This animal is generally scarce, but in certain districts, I believe,
of an alpine character, it is abundant. It excavates very extensive
superficial burrows, no doubt, for the purpose of feeding on the roots
of plants, as in the case of the _Ctenomys Braziliensis_, the habits of
which have just been described. Horses passing over districts frequented
by these animals, sink fetlock deep through the turf. I procured my
specimen from Valparaiso, where the country-people called it
‘Cururo.’”—D.
