Mesosciurus gerrardi zuliae, ALLEN, Bull. Amer. Mus. Nat. Hist., vol. 34, p. 246,

Sciurus gerrardi cucutae AuLEN, Bull. Amer. Mus. Nat. Hist., vol. 33, p. 592, 
1914 (El Guayabal). 
Holotype—Adult male, skin and skull, C.N.H.M. No. 16585; 
collected March 1, 1908, by Ned Dearborn. 
Type locality—Orope, a small railroad station on the Rio Orope, a 
tributary of the Zulia, near the Colombian border, Zulia, Venezuela; 
altitude approximately 25 meters. 
Distribution.—The upper Rio Zulia drainage area in Colombia and 
Venezuela, south and west across the Cordillera Oriental to the Rio 
Magdalena in Santander; altitudinal range from approximately 20 to 
1,050 meters above sea level. 
Characters.—Larger, darker, with more contrasting reddish shoulder 
regions than griseogena and meridensis, paler, less uniformly dark 
agouti than farrae, paler with less contrasting shoulder regions than 
maracaibensis. 
Coloration.—The four topotypes of cucutae, all females, and one 
female topotype of zuliae are at hand. In view of the short distance 
in the same general region separating the type localities of these two 
described forms, it is not surprising that they should conform exactly 
to each other. Apparently Allen based his distinctions on comparisons 
of the Guayabal specimens with those here described as maracaibensis 
but which he assigned to zuliae. In general, the Guayabal series and 
the topotype are dark agouti with comparatively little contrast in 
the shoulder regions; posterior half of back more nearly uniformly 
black than median dorsal band on anterior half. Underparts reddish 
except in one of the Guayabal specimens which shows a broad band 
of white on throat and neck, and white on axillae and pubic region. 
Tail above black basally and terminally, orangeous medially, under- 
side grizzled basally, black terminally, tricolor (orange, black, grizzled) 
medially. 
The most nearly agouti specimen of the Guayabal series serves 
to form an almost unbroken gradient in coloration between zuliae 
and the series of griseogena from San Julidn. The topotype agrees 
more nearly than the others with specimens of tarrae from the upper 
Catatumbo. 
GRAMALOTE (2 females): Specimens from 30 kilometers west of 
Cicuta, 1,020 meters altitude, are quite intermediate in characters 
between the Guayabal zuliae and the series of meridensis from the 
Paéramo de Tamé. As compared with the former they are smaller, 
with longer, thicker pelage, less black on upper parts, less red on
