184 SENIOCEBUS 



In his tribe Hapalina the species of Marmosets are in this List 

 arranged under four genera: Leontopithecus, CEdipus, Midas 

 and Seniocebus. In Leontopithecus are placed rosalia, and 

 CHRYSOMELAS; CEdipus has titi — O. cedipus; and geoffroyi 

 both in CEdipomidas ; Midas contains mystax ; labiatus ; ruii- 

 venter = Leontocebus labiatus ; leucogenys = Leontocebus 

 devillii ; flavifrons — Leontocebus fuscicollis ; ursulus ; 

 and ursulus var. 2 = Cercopithecus midas (Linn.). Senioce- 

 bus contains but one species bicolor Spix. 

 Descriptions are given of the following species which, evidently, 

 the writer had never seen: (Midas) rufoniger = Leontocebus 

 NiGRicoLLis ; (M.) devillii; (M.) nigrifrons; (M.) illigeri; 

 (M.) fuscicollis ; and (M.) weddeli ; the last two supposed to 

 be the same

The Tamarins in this work are included with the Marmosets in 

 the genus Hapale. The Author places them in one division with

 (H.) rosalia; (H.) chrysomelas ; and (//.) chrysopyga; all 

 Leontocebus; B. has (H.) leonina; o. subdivision, has (//.) 

 bicolor, a Seniocebus; in b. are (//.) cedipus; and (H.) 

 geoffroyi; both in CEdipomidas. D. subdivision a. includes 

 (//.) labiata; (//.) pileata; and (H.) mystax; b. has (H.) 

 devillii; (//.) weddeli; (H.) illigeiTn, (H.) nigrifrons; 

 (H.) fuscicollis; and (H.) nigricollis; all belonging to 

 Leontocebus; c. (H.) Ursula; and (//.) midas; both in Cer-
