one species (M.) tamarin = Cercopithecus midas; the C. 

 ursulus being regarded as the male of middle age, and Leon- 

 tocebus fuscicollis being the young. The Genus CEdipus has 

 CEdipus titi = (Edipomidas cedipus ; Cercopithecus bicolor 

 (Spix), being the immature animal. Under the genus Leon- 

 topithecus = Leontocebus, of the subgenus Marikina, the 

 following species and varieties are given: L. aurora = L. 

 rosalia ; L. fuscus = L. leonina ; L. ater = L. chrysopygus ; 

 var. A. and var. B. L. chrysomelas. The method of arrange- 

 ment adopted by this Author is unsatisfactory and somewhat 

 confusing.
