(Note from website editor (1998): While in the Museum der Naturkunde in 1989 in what was then East Berlin I took a photograph of the specimen there alongside the illustration accompanying Spix's description. You can see it by clicking here.

Further note (2008): I have been sent photos of the specimen collected by Spix, which is in the natural history museum in Munich.
