Pearson 1982 95 Dec. 12 Took the Tas-Choliffa bus to Valdivia. Saw one clump of the small bamboos blooming, high at the pass to Panguipulli. No amaranths blooming yet, no roses on the Argentine side but wild roses blooming near Valdivia. Dec. 13 Gave all-day seminar at the Instituto de Ecología y Evolución; 6 students (4 F 2 M) + Roberto Murúa and Sergio González. Dec. 14 Seminar by Dr. Figueroa, a statistician, covering Bickel, Smith, Jolly, Jackson, Soler, etc. Murúa showed me the beast they have been calling colombus megalocephalus. They have 3 good skulls, 1 skin, and 2 bodies in alcohol, which I did not look at. The skin is very dark, above and below, big leafy ears (about 20 cm, if I remember correctly), long tail (much longer than any chlamyphorus), and long front toesails. Body size, tail length, and color about as in a big colombus longipes from Peru but its ear dogs and claws longer. The teeth are simple, as in Gastreus but bigger, and the zygomatic notch is very narrow, very short, very flattened as in Agujayturus or the Peruvian cloud-forest genus. The canines are not prominent and not white; maybe not so articulated as megalocephalus, (no megalocephalus here to compare with), nor megalocephalus. I think it must be an undescribed species of a genus close to Gastreus. The specimen came from the San Martín field station (about 50 km N of Valdivia).
