Didelphis marsupialis Linnaeus, 1758

VOUCHER MATERIAL: Waqanki: 1 adult male ( FMNH 203508 ) ; Tingana: 1 adult female ( MUSM 39246 ) ; see table 1 for measurements.

IDENTIFICATION: We consulted descriptions and measurements of Didelphis marsupialis provided by Gardner (1973), Patton et al. (2000), Voss et al. (2001), Lemos and Cerqueira (2002), Cerqueira and Tribe (2008), and Hice and Velazco (2012). Our Mayo River basin specimens exhibit all the diagnostic characteristics of this species (e.g., ears entirely black, lack of facial markings, jugal embracing the squamosal zygomatic process both above and below) and fall within the range of measurements previously reported for Didelphis marsupialis (table 1).

REMARKS: Our two individuals were shot, MUSM 39246 at 06:00 hours in an agricultural field and FMNH 203508 at 22:00 hours in a tree overhanging a chicken coop.
