Holotype.—Adult female, skin and skull, M.C.Z. No. 8144; collected 
March 26, 1898, by W. W. Brown, Jr. 
Type locality —Pueblo Viejo, Rio San Antonio, northern slope of the 
Sierra Nevada de Santa Marta, Magdalena, Colombia; altitude 853 
meters. 
Distribution.—From near sea level to approximately 2,000 meters 
on the northern base and slopes of the Sierra Nevada de Santa Marta, 
south through the mountains to the southern slopes at altitudes 
ranging between 1,000 and 2,000 meters. The type locality, on the 
northern slopes of the mountains, is situated at an altitude considerably 
less than the 8,000 feet given for it by Brown and cited by Bangs in 
the original description. 
Characters.—Darkest and smallest of the Sierra Nevada de Santa 
Marta squirrels, with thicker and longer pelage. 
Coloration.—The subspecies has been well described by Bangs and 
by Allen. The specimens described below were taken on the southern 
slopes of the mountains. 
Pursio Bretyto (9 males and 8 females): The series shows a con- 
tinuous gradation between saltuensis and agricolae (nomen novum) 
from the type locality and from El Salado. It ranges from four 
specimens more or less uniformly mars orange (except for white ventral 
parts) with a very light ticking of black on the back, through indi- 
viduals with increasing amounts of black, to one uniformly dark 
agouti with a heavy black median dorsal band and black fore and hind 
feet. The intermediate agouti individuals with contrasting shoulder 
regions exhibit a bright reddish lateral line. With the increasing 
amount of black on the dorsum, some of the hairs become entirely 
black while the contrasting color of the annulated hairs becomes 
increasingly yellower. The tails are fairly uniformly orangeous or 
reddish above, except for the basal portions which agree with the 
rumps; beneath they range from uniformly colored to bicolor and tri- 
color. 
Remarks.—Two specimens of saltuensis from Cincinnati and Don 
Diego (collected by Carriker) show the color of saltuensis with the
