Here is a (nearly complete) mammal species list at the Smithsonian Museum of Natural History in Washington D.C. I am missing a few species of rodents, a few South American and Asian species and perhaps a couple spread around the museum I did not take into account. This was made by compiling species in photos in the gallery, photos online and the virtual tour of the museum that can be found here: National Museum of Natural History. Some of the specimens were inaccurately signed or I had to take a (hopefully slightly educated) guess at what the species in question was. Some have only been narrowed down to genus level. If anyone has a more complete/accurate list, feel free to post it below - I don't believe anything of the sort has been posted on Zoochat before. NB: there is an online catalogue of the Museum's complete collections, which are extremely impressive, and I sincerely wish more of them were exhibited in the areas devoted to mammals (the galleries seem quite sparse in relation to especially the Paris Natural History Museum). For example, I wish that the zoo displayed one of its Bay or Flat-headed cat specimens. I have highlighted potentially interesting/rare species in red. Anyway, here goes: Bone Halls (all skeletons unless specified otherwise) Platypus Short-beaked echidna Brush-tailed possum Greater glider (this was signed as a Great flying phalanger) Koala Great grey kangaroo Tiger quoll (signed as a 'native cat') Marsupial mole sp.
