" Los Tojos. Iiilialjit the sandy parts of tlie tops of tlie 

 rocky hillocks. Were captured in traps phvced in the runs 

 made below the soil, but the bait used, potato or maize, was 

 not eaten. Come out of their burrows at sunrise and niglit- 

 fall. Not very common, living isolated in small families." —

11. Octodontomys gliroides, Gerv. & d'Orb. 



cJ. 38 ; ? . 30, 31, 37, 39. Maimara. 2600 m. 



This is my Neoctodon simonsi, in the description of which 

 I accidentally used a generic name preoccupied in beetles, 

 and, as to the species, was deceived by a figure of the teeth 

 of Octodon degus being put — without a word of explanation — 

 on the plate of " Octodon gliroides,''' so that I too rashly 

 supposed that the latter was really an Octodon. 



This beautiful and conspicuous animal is by far the most 

 characteristic form of what I have therefore ventured to call 

 the " Octodontomys area." The type was obtained at 

 La Paz ; Mr. Simons got specimens at Oruro, Challapata, 

 Livichuco, and Potosi, and Sr. Budin's specimens show that 

 the species ranges into ('entral Jujuy. 



" The ' Chozchori ' are found in the broken rocks of the 

 hills called ' Volcanoes,' or in the walls built of rough stones. 

 Occur up to a height of 3000 m. Are not wild, and are 

 easily shot. Diurnal, seen everywhere in the early morning 

 and late afternoon. Common throughout the district of 

 Uraahuaca."— ^. B.
