MAMMALS OF NORTHERN COLOMBIA—HERSHKOVITZ 23 
SCIURUS GRANATENSIS PERIJAE, new subspecies 
Holotype.—Adult male, skin and skull, U.S.N.M. No. 279892; col- 
lected December 25, 1942, by Philip Hershkovitz; original No. 1230. 
Type locality.—Sierra Negra, above Villanueva, on the western 
slope of the Sierra de Periji, Valledupar, Department of Magda- 
lena, Colombia; altitude 1,265 meters. 
Distribution.—Northern half of the Sierra de Perij&é (Cordillera 
Oriental), Department of Magdalena, at altitudes ranging from approx- 
imately 800 to 2,500 meters. At lower altitudes, forms intergrading 
with splendidus on the west, and maracaibensis (nomen novum) to the 
east probably occur. 
Characters.—Contrastingly colored, darker, with more black and 
smaller than splendidus; paler, with less black than maracaibensis; 
more contrastingly colored, less agouti, than tarrae and meridensis. 
Coloration of holotype—Pelage thick and soft. Mixed orange and 
black on lower half of back continued forward as a broad median 
dorsal band to nape, shoulder region more uniformly orange (xanthine 
orange); black tipped hairs plumbeous basally followed by successive 
bands of orange, black and orange, the lower orangeous band less red 
than the subterminal one, both bands becoming yellower toward 
posterior portion of body and on head. Sides of body like back but 
with less black and with broader bands of orangeous. Nose, sides of 
face, chin, and upper half of throat buffy.- Hind legs, except for white 
ventral portions, mixed orange-rufous and black; forelegs more nearly 
uniformly orangeous. Belly, chest, neck, and lower half of throat 
sharply defined white. Tail above mars orange, the proximal portion 
mixed with black, on underside, the hairs with six bands, the basal 
black followed by successive bands of yellow, black, orange, black, 
and broadly orange terminally; the general effect is tricolor with mars 
orange externally, black medially, mixed black and yellow internally. 
Measurements of holotype (in millimeters).—Head and body, 236; 
tail, 216; hind foot, 59; ear, 29; condylobasal length, 51.3; zygomatic 
breadth, 33.0; length of nasals, 17.0; orbital constriction, 18.9; post- 
orbital width, 19.0; width of braincase, 23.5; alveolar length of molar 
row, 10.1. 
Coloration of the paratopotypes (12 males, 17 females).—Most of the 
specimens, like the holotype, are of the contrasting agouti type. 
Ticked condition of rump continued forward as a median dorsal band 
sharply defining the orangeous or reddish shoulder regions. Red 
annulations of hairs of rump paler than corresponding ones of anterior 
half of back; in many individuals, these bands are yellowish and, 
together with the black, give an olivaceous appearance to rump. 
In some specimens there is a marked concentration of black on median 
dorsal portion of back. Two individuals are nearly uniformly reddish
