tained there was shot from a coco palm and its stomach was well filled 
with coconut. 
At Orope, the type locality of S. v. zulie, the climate is so much 
more humid and the vegetation so much more luxuriant than at the 
northern end of Lake Maracaibo, that considerable difference in the 
animal life should obtain. However, it does not seem advisable at 
present to attempt the separation of the squirrels of these regions. 
Those from the more arid region have somewhat lighter heads, more 
intensely ferruginous feet, and broader, more abundantly haired tails. 
Sciurus griseogena tamz subsp. nov. Tama Squirrel. 
Type from Paramo de Tama, Colombia. Alt. 6,000—7,000 ft. No. 
18736 Field Museum of Natural History. Male adult. Collected 
Feb. 14, 1911, by W. H. Osgood and S. G. Jewett. 
Characters. Similar to Sciurus g. meridensis, but paler colored 
throughout; general color of upperparts only slightly darker than in 
S. quebradensis, but more rufescent on shoulders; tail and other parts 
quite different.. Upper parts mixed clay color and blackish; shoulders 
heavily suffused with ochraceous continuous with the same but slightly 
heightened color on the outer sides of the forelegs; postauricular spot 
cream buff bordered with ochraceous buff. Underparts bright tawny 
ochraceous and white, the latter variable in extent, generally extending 
medially from the throat to the groin, widening on the chest and extend- 
ing to the forelegs; fore and hind feet tawny ochraceous, on the meta- 
podials more or less mixed with dusky; upper side of tail about as in 
S.g. meridensis, base (2inches) grizzled, middle (4inches) clear ochraceous 
buff, tip (1% in.) black; under side of tail correspondingly colored but 
middle part strongly mixed with blackish. 
Skull practically as in griseogena and meridensis; rostrum apbaemntte 
a trifle more attenuate. 
Measurements. Average of four topotypes: Total length 396 
(385-416); head and body 216 (209-223); tail vertebrae 180 (176-193); 
hind foot (c. u.) 54 (53-55). Skull of type: Greatest length 53; basilar 
length 39.3; zygomatic breadth 30.5; nasals 16.7; interorbital breadth 
17; diastema 13; maxillary toothrow 8.6. 
Remarks. This form is most closely allied to Sciurus g. meridensis 
but is well distinguished by its general lighter color and the extensive 
white markings on the under parts. These white markings are variable, 
but three of the four specimens taken have them highly developed. 
The extensive dense forests on the upper slopes of the Paramo de 
Tama no doubt harbor considerable numbers of these squirrels, but in
