CALLITHRIX 227 



median length of nasals, 7; length of mandible, 28; length of lower 

 molar series, 9. 



The type of this form is no longer in the Paris Museum. There 

 are several specimens, however, in the collection, the earliest of which 

 bears date 1822, ten years after Geoffroy described the species. In all 

 the examples, the name penicillatus is attributed to Kuhl, who gave 

 the species in his Beitrage Zoologie eight years after Geoffroy had 

 described it.

Callithrix penicillata jordani Thos., Ann. Mag. Nat. Hist., XIV, 

 7th Ser., 1904, p. 188. 



Type locality. Rio Jordao, S. W. Minas Geraes, Brazil. Type in 

 British Museum. 



Genl. Char. Like C. penicillata, but width of the middle upper 

 incisor about one half the length, instead of two thirds as in the other 

 species, and it is also longer and narrower. 



Color. Face mars brown; spot on forehead and short hairs on 

 lips white ; top of head brownish black ; nape, neck, and ear tufts black ; 

 the hair on back of head very long ; general color of upper parts gray, 

 banded with black, this being caused by the subterminal black band on 

 the hairs showing alternately with the gray tips; none of the ochra- 

 ceous color of the hairs showing, as it so conspicuously does in the 

 other species ; arms and legs ochraceous buff washed with gray ; throat 

 pale brown; upper part of chest, and a line in center of abdomen 

 ochraceous washed with gray ; inner side of arms, elbow to wrist black ; 

 above elbow ochraceous buff and gray ; inner side of legs pale clay color, 

 with a black spot near the body; hands and feet mixed black and 

 orange ; tail ringed with black and white. Ex type British Museum. 



Measurements. Total length, 533; tail, 298; foot, 58; ear, 20. 

 Skull: occipito-nasal length, 42; Hensel, 30; intertemporal width, 21; 

 palatal length, 13 ; zygomatic width, 28 ; breadth of braincase, 25 ; 

 median length of nasals, 8 ; length of upper molar series, 9 ; length of 

 mandible, 27.5; length of lower molar series, 9. Ex type in British 

 Museum. 



This subspecies is not so gray as C. penicillata, but darker and 

 browner; the band above the slate colored base of the hairs is tawny 

 and not ochraceous, and this causes the general darker hue of the 

 animal; the under parts are much lighter, and more yellowish brown 

 on sides of abdomen and inner side of thighs.
