The Macacus speciosus of M. F. Cuvier is stated by M. Tem- 

 minck to be founded upon an immature specimen of a species of 

 Macacus which inhabits Japan ; the habitat of Molucca Islands 

 given by M. F. Cuvier being founded upon error. The specimen 

 was originally taken from Japan to Java, where it died ; the skin 

 was preserved, and M. Diard having obtained possession of it, sent 

 it to the Paris Museum ; and as there was no label attached, M. F. 

 Cuvier imagined it to be a native of the place whence M. Diard had 

 sent it.
