Extreme caution must be exercised in attempting to apply the 
findings from the study of the squirrels of the middle Rio Cesar to 
those of other regions. The Cesar series represents a fairly homogene- 
ous group with the variation in color restricted to the conditions 
between uniformly reddish and uniformly orangeous. The squirrels 
taken at three different stations in the Sierra Nevada de Santa Marta 
show a variety of color patterns and combinations of patterns but do 
not supply clues that may lead one to suspect that their differences 
in pelages, color phases, and color patterns are related to changes in 
the environment of any one of the localities. The three series are 
listed with the pertinent data: 
Colonia Agricola. Altitude 335 meters above sea level. 17 specimens from 
January 15 to March 2,1942. Period rainy with afew cleardays. All conditions 
of color, pattern, and pelage as noted for the subspecies agricolae. 
Pueblo Bello. Altitude 1,067 meters. 17 specimens from April 24 to May 17, 
1942. Period very rainy. All conditions of color, pattern, and pelage as noted 
for the subspecies saltuensis. 
El Salado, Altitude 430 meters. 19 specimens from June 23 to July 21, 1942. 
Dry period with occasional rains. Agree with the Colonia Agricola series of 
agricolae and show an even wider range of variation.

comparée, vol. 1, p. 8, pl. 3, No. 7, 1811 (1812); zbid., vol. 1, livr. 1, 1805, 
first issue, fide Sherborn, Ann. Mag Nat. Hist., ser 7, vol. 3, p. 428, 1899. 
Type.—No type specimen preserved. Name based on description 
of the squirrels observed and the original figures (op. cit.) of tongue, 
larynx, and hyoid bone of an individual dissected in the field. 
Type locality.—Cartagena, Department of Bolivar, Colombia. 
Disiribution.—Department of Atl4ntico, and Province of Cartagena, 
northwest Bolivar Department, Colombia. 
Characters——Upperparts orangeous, underparts sharply defined 
white. Paler than splendidus and gerrardi; slightly smaller and more 
red than bondae; more uniformly orangeous than morulus and sala- 
quensis. 
Coloration.—The series of six males and eight females from Ciénaga 
de Gudjaro, 53 kilometers northeast of Cartagena, are considered 
typical. In most individuals of this series the entire surface of the 
dorsum ranges from nearly uniformly orange to orange-rufous, and 
mars orange in the darkest specimens; hairs orange with or without 
fine black tips, becoming paler toward the gray bases. In two 
specimens lower back mixed orange and black. Sides of body and 
limbs like back or more yellow, and without black; chin and sides 
of face paler than sides; crown like back; nape like crown or slightly 
darker and contrasting with crown and back. Tail with basal portion 
faintly mixed with black to nearly entirely black, tip like middle
