MAMMALS OF NORTHERN COLOMBIA—HERSHKOVITZ 35 
Table 1 shows the intergradation in color patterns. The localities 
have been arranged in an order showing geographical continuity. 
Where this continuity is broken, as between the Bonda series from 
the Sierra Nevada de Santa Marta and the San Julidén series from 
northern Venezuela, a space on the chart separates their localities. 
The symbols for the patterns are explained on page 9. It will be 
noted that the color pattern does not describe the particular color 
tone or color phase on the dorsum, or the color of the underparts. 
Nevertheless, as shown in the descriptions and discussions, the gra- 
dations in the colors themselves, both of upper and lower parts, the 
extremities included, coincide with those of the color patterns. 
SUPPLEMENTARY LIST OF THE SOUTH AMERICAN SUBSPECIES OF | 
SCIURUS GRANATENSIS Humboldt 
Unless otherwise indicated, the types and additional material in- 
cluding topotypes of the following named forms have been examined 
by the author. 
SCIURUS GRANATENSIS GERRARDI Gray 
Sciurus gerrardi Gray, Proc. Zool, Soc. London, 1861, pt. 1, p. 92, pl. 16, 1861. 
Type locality—New Grenada. Restricted by Allen (1915, p. 308) 
to ‘somewhere between the ranges of the zuliae-cucutae group... 
and . . . baudensis in northern Colombia.”’ 
Remarks.—Allen referred a specimen from the Rio San Jorge, 
Bolivar, to gerrardi. Two squirrels, one from Monteria, another from 
Jaraquiél, both on the Rio Sint, Bolivar, agree with the color plate 
of gerrardi. ‘They are more red than typical granatensis and the tails 
of both are tipped with black. The specimens, collected by Carriker 
in 1916, are preserved in the Carnegie Museum. 
SCIURUS GRANATENSIS SALAQUENSIS Allen 
Sciurus gerrardi salaquensis ALLEN, Bull. Amer. Mus. Nat. Hist., vol. 33, p. 592, 
1914, 
Mesosciurus gerrardi baudensis ALLEN, Bull. Amer. Mus. Nat. Hist., vol. 34, p. 
308, 1915 (Baudo). 
Type locality—Rio Salaqui, a tributary of the Atrato, northern 
Chocé, Colombia. 
Remarks.—Doubtfully separable from morulus Bangs. 
SCIURUS GRANATENSIS VALDIVIAE (Allen) 
Mesosciurus gerrardi valdiviae ALLEN, Bull. Amer. Mus. Nat. Hist., vol. 34, p. 
309, 1915. 
Type locality —Puerto Valdivia, lower Rio Cauca, Antioquia, central 
Colombia; altitude 360 feet.
