PIGMY MARMOSET. 



Type locality. Forest near Tabatinga on the Rio Solimoens, 

 Brazil. Type in Munich Museum. 



Geogr. Distr. Forest along the Solimoens and Ucayali rivers, 

 Brazil, north into Mexico. (Bates). 



Genl. Char. Size diminutive; ears small. 



Color. Top of head dark brown, hairs pale yellow tipped with 

 dark brown; hairs on back black at base, then yellowish white, then 

 black, giving this part a mottled appearance ; limbs blackish brown and 

 yellow ; under parts yellowish. Ex type Munich Museum. 



The type is in bad condition, and a correct description of its pelage 

 as it was when the animal was living is impossible, as the fur is dis- 

 colored and the hair is mostly gone from the tail. The skull is in the 

 skin, and judging from the teeth, which are exposed, the animal is fully 

 adult, although so small in size. 



Color. Adult. Head, neck and back between shoulders speckled 

 dark brown and gray, or dark brown and clay color ; back black mottled 

 with buff ; gray on rump ; outer side of arms like head ; outer side of 

 legs like back; throat and upper part of breast yellowish brown; ab- 

 domen gray, inner side of legs yellowish brown ; hands and feet yellow- 

 ish ; tail above banded with black and tawny, beneath tawny for basal 

 two thirds, banded with black and tawny for remainder. 



Measurements. Total length, (skin), 325 ; tail, 165 ; foot to end of 

 nails, 46. Skull: occipito-nasal length, 34; intertemporal width, 19; 

 palatal length, 12 ; zygomatic width, 23.5 ; breadth of braincase, 22 ;
