Jacchus rufiventer [now Sanguinus labiatus rufiventer] - Red Bellied Marmoset [Red-Bellied Tamarin]
This is actually NOT a marmoset, as the authors believed it was. Tamarins are closely related to marmosets, but they have canine teeth that are larger than their incisors. This means that they can’t gnaw on tree bark to eat the gum underneath, like marmosets do. Despite this, their diet is largely the same as their close cousins.
