ochraceous forms of the western border of the range of the group. With a 
series of more than 20 specimens before me from Santa Marta, it is difficult 
to decide whether D. colombiana is more closely affiliated with typical 
vartegata than with typical fuliginosa. In all probability D. awrea and D. 
yungarum will also prove to be closely related inter se through an inter- 
mediate form in southern Bolivia. 
Dasyprocta variegata zamore subsp. nov. 
Type, No. 36582, 9 ad., Zamora (altitude 2000 feet), Ecuador, Nov. 1, 1913; 
Wm. B. Richardson. . 
Similar to Dasyprocta variegata Tschudi, but the annulations of the tips of the 
hairs much broader, more abundant, and of a more reddish tone — deep ochraceous 
tawney instead of yellow, and the rump hairs with rather long white tips in unworn 
specimens, instead of practically wanting as in variegata. 
Represented by 4 adult females, all collected by Wm. B. Richardson, as follows: 
Zamora, 1; Naranjo, 2; another labeled ‘“‘Quito”’ by the collector, but doubtless 
erroneously, although unquestionably from Ecuador. 
Collector’s measurements of the type and the two Naranjo specimens: Total 
length, type 620, Naranjo specimens 580, 650; tail —, 30, 30; hind foot, 120, 120, 120. 
Four skulls, total length, 109 (105-115); condylobasal length, 101 (96.5-103); zygo- 
matic breadth, 48.6 (47-49.5); interorbital breadth, 29.8 (28.5-31.5); diastema, 26 
(25-28); maxillary toothrow, 19.5 (1920.5). 
D. v. zamore differs from typical D. variegata as indicated above, and 
from D. v. yungarum especially in the color of the mid-ventral surface, 
which is “ orange-ochraceous”’ in yungarwm and white in gamore. 
Although Zamora and Naranjo are situated respectively on the eastern 
and western slopes of the Andes, the specimens from these two localities 
do not differ appreciably in coloration or other features. 
Dasyprocta variegata chocoensis subsp. nov. 
Dasyprocta variegata variegata ALLEN, Bull. Amer. Mus. Nat. Hist., XXL p. -70, 
April 19, 1912. 
Type, No. 32153,  juv., Los Cisneros (altitude 600 feet), Choco district, Colom- 
bia, March 9, 1911; Wm. B. Richardson. 
Similar in general coloration to Dasyprocta variegata zamore, but with much 
longer white tips to the hairs of the rump, and the ochraceous annulations of the 
hairs of the back and flanks broader and more yellow, varying in different indi- 
viduals from ochraceous buff to ochraceous orange. 
Total length, type ( juv.) 550 mm., topotype (7 ad.) 580; hind foot, 120, 180. 
Skulls of same specimens, total length, (type) —, (topotype) 111.5; condylobasal 
length, 100, 102; zygomatic breadth, 44.6, 49; interorbital breadth, 28.5, 29.3; 
diastema, 29, 29.6; maxillary toothrow, 22, 19.
