Callithrix penicillata jordajii, subsp. u. 



Mr. Robert has obtained two series of marmosets referable 

 to Calhthrix penicillata, Geoff., one from Laraariio, near 

 Bahia, and the other Irom the Rio Jordan, Province Araguay, 

 Minas Geraes. The former, on geographical grounds, may 

 be regarded as the true penicillata, which was simply 

 described as from Brazil, and from this animal the Jordao

 distinction. 



Size averaging slightly larger than in penicillata. General 

 tone of the light colour of the back bufiy whitish instead of 

 pure greyish white. Under surface with less black on the 

 throat, this part being grey, only slightly washed with

 strongly suffused with dull yellowish, the hairs of penicillata 

 being blackish tipped with white over the whole under 

 surface. Flank-hairs, where overhanging belly, less vividly

 ring dull instead of vivid orange, and their subterminal dark 

 band narrower and less conspicuous. Face less brightly 

 picked out with black and white, the wiiitc patches below the
