The early technical history of this species is somewhat obscure. 

 Cuvier briefly mentioned it under a French name in the tirst edition 

 of his Reg-ne Animal (1817), saying- that it is from 'Mamaica, and prob- 

 ably the other Antilles." A somewhat crude figure is added, and from 

 the statement that he had "found berries in its stomach" it is plain 



«To the great French zoologist G. Cuvier, because of his having indicated the 

 species in the first edition of Regne Animal, 1817.
