Hochlanddegu (O. d. clivorum)
J.A. Wolffsohn sammelte vor einigen Jahren einige Exemplare von Octodon degus aus dem Tiefland, aber auch einige von Palo Alto, östlich von Santiago, welche als neue "Rasse" vorgestellt werden sollen:
"Octodon degus clivorum, subsp. n.
Size slightly greater than in O. degus, but less than in O. bridgesii. Colour markedly colder and more greyish than in the warm brown O. degus. General colour above near "light greyish olive" of Ridgway, typical degus being more "buffy brown." Under surface washed with dull yellowish white, with but little trace of the distinctly buffy or even ochraceous wash of degus. No axillary or inguinal white patches, such as are commonly present in O. bridgesi. Skull essentially similar to that of degus, though rather larger. Dimensions of the type: Head and body 183 mm.; tail 134; hind feet 37; ear 30. Skull: greatest length 44; condyle-incisive length 41.7; zygomatic breadth 23.6. Hab. of typical series. Puente Alto, E. of Santiago. Altitude 800 m. Type. Adult male. B.M. no. 4. 1. 7. 13. Original number 262. Collected 30th November, 1903. Then specimens. When sending his Octodons, Mr. Wolffsohn gave me a remarkable account of the different species of rodents which occur living together in this region, as from the same holes he captured Octodon degus, O. bridgesii, Abrocoma bennettii, Phyllotis darwini, Akodon olivaceus, Abrothrix longipilis, Oryzomys longicaudatus and Rattus rattus; besides Marmosa elegans (letter of 30th July, 1909)."
