nustrangi, Meika A. 1993. Journal 28 ubatuba-SP Brazil We photographed all but the Proechimys individuals captured. Seu Salvador, Keeper of the farm names Proechimys : ratopaca; opossums: guaiguicas Didelphis : raposinha. He told us Proechimys eat cacao. Opossums come to eat bananas left to ripen. He says Proechimys climb the cacao tree, and eat the fruits. We caught 2 Didelphis, on 2 # days, in two different traps, and released them. The Metachirus individual, male, had a dark area on its abdomen, more or less where the marsupial would be in a female of a species with marsupium. I had never seen a male w/ such a stained, pigmen- ted skin area on its belly before. I found no gular gland on this male.
