short, stiffer pelage of bondae. Five other Cincinnati specimens of 
the same series have been assigned to bondae. The region in question 
is one where intergradation between the two races may be expected. 
In the eastern, higher parts of Cincinnati, saltuensis should occur 
while the lower, western part, is the habitat of bondae. The appear- 
ance of both reddish and dark agouti individuals of saltuensis near 
the coast (see bondae, antea p. 13) is duplicated in Pueblo Bello, which 
is well in the interior of the mountains and distant from the coast. 
However, the tendency in the Sierra Nevada is for the squirrels to 
become agouti and progressively darker with the increase in altitude. 
The squirrels seen above 2,000 meters altitude in the vicinity of San 
Sebastian are blackish. Of the four more or less uniformly reddish 
specimens of the Pueblo Bello series described above, two are imma- 
ture, one is subadult. 
Specimens examined.—Twenty-four. Pueblo Viejo, 2 (C.M.); 
Minca, 1 (C.M.); Cincinnati, 2 (C.M.); Don Diego, 1 (C.M.); Palo- 
mino, 1 (U.S.N.M.); Pueblo Bello, 17 (U.S.N.M.). 
SCIURUS GRANATENSIS AGRICOLAE, new subspecies 
Holotype.—Adult male, skin and skull, U.S.N.M. No. 279775; 
collected March 1, 1942, by Philip Hershkovitz; original No. 208. 
Type locality.—Colonia Agricola de Caracolicito, Rio Ariguani, on 
the southern slopes of the Sierra Nevada de Santa Marta, Department 
of Magdalena, Colombia; altitude 335 meters. 
Distribution.—Southern and eastern slopes of the Sierra Nevada de 
Santa Marta at altitudes ranging between 200 and 1,000 meters. 
Characters.—Size as in bondae but darker, redder; larger, paler, with 
less black than saltuensis; smaller, less uniformly colored, more agouti, 
than splendidus. 
Coloration of holotype.—Back and crown mars orange lightly ticked 
with black; hairs tipped black, broadly banded mars: orange sub- 
terminally and becoming paler, yellower toward the gray bases. 
Sides of body, neck, fore and hind limbs, except for white ventral 
portions, mars orange, the hairs becoming paler toward the base. 
Sides of face, rostrum, chin, ochraceous-buff ticked with black, more 
tawny beneath the eyes. Underparts white as usual. Tail above 
burnt sienna, beneath weakly defined tricolor, the hairs yellowish 
basally, black medially, burnt sienna terminally. 
Measurements of holotype (in millimeters)—Head and body, 238; 
tail, 240; hind foot, 60; ear, 30; condylobasal length, 51.6; zygomatic 
breadth, 32.5 (approximate); length of nasals, 17.0; interorbital con- 
striction, 18.7; postorbital width, 18:7; width of braincase, 23.9; 
alveolar length of molar row, 10.0. 
Coloration of the paratopotypes (9 males, 7 females).—The series 
exhibits the two dominant color phases in many forms; some specimens
