Comment: In the Mammal Species of the World (Groves 2005), Grandidier (1867) is erroneously listed as the describer of Propithecus deckenii . However, Grandidier (1867) described Propithecus Verreauxi [sic] as a new species and made no mention of Propithecus deckenii . The first description and name of Propithecus deckenii appeared in Peters (1870).
