 but which are now placed in the genus Callithrix. It is 

 divided into several subgenera, and the few species recognized 

 have many varieties. 1st subgenus is Hapale with two species 

 (H.) leucotis = C. jacchus; and (//.) mclanotis = C. peni- 

 cillata Humboldt. The first has four varieties, all valid 

 species, viz., A. C. aurita; B. (/.) vulgaris = C. jacchus; C. 

 C. albicollis ; C. humeralifer ; the second has one "viellesse," 

 C. LEucocEPHALA. 2nd subgenus Mico has but one species, 

 C. ARGENTATA. 3rd subgcnus Midas contains species of 

 Seniocebus, and 4th of CEdipus, and 5th of Leontocebus.
