M. Havifrons = L. fuscicollis (Spix) ; (M.) illigeri; and 

 (M.) weddeli. All these are now included in the genus 

 Leontocebus. (M.) cedipus, and (M.) geoffroyi, are now 

 placed in the genus CEdipomidas; while (M.) ursulus and 

 (M.) rufimanus are arranged in the genus Cercopithecus ; 

 and (M.) bicolor in the genus Seniocebus.

In this paper five Tamarins are given, being those described in 

 the Comptes Rendus in 1848 and 1850. They are (Midas) 

 pileatus; (Hapale) devillii; (Hapale) nigrifrons; 

 (Midas) Havifrons = Leontocebus fuscicollis; and 

 (Midas) rufoniger = L. nigricollis. Midas and Hapale were 

 used at different times for the generic name, but in this paper 

 Midas is selected as the name of the genus. 



1855. Wagner, Schreber, die Sdugthiere in Abbildungen nach der 

 Natur mit Beschreibungen. Supplementband. 

 A list similar to that given by this Author in 1840, but enlarged. 

 The additional species are Leontocebus ruiiventer = L. labi- 

 atus ; L. fuscicollis ; L. nigricollis ; L. weddeli ; L. illigeri ; 

 and CEdipomidas geoffroyi. All are placed in the genus 

 Hapale with three subgenera, Jacchus, Liocephalus, and Leon- 

 tocebus. The species now arranged in the genus Callithrix 

 are also included in Hapale, and in the first two subgenera, but 

 Leontocebus has merely the species of Marmosets belonging 

 to it, and to CEdipomidas. No new species described.
