FOUR NEW MAMMALS FROM VENEZUELA. 
BY WILFRED H. OSGOOD. 
Among South American mammals obtained in recent years by the 
Field Museum of Natural History are four from western Venezuela 
that appear to be undescribed. They are as follows: 
Peramys palliolatus sp. nov. 
Type from San Juan de Colon, State of Tachira, Venezuela. A\l- 
titude 2,500 ft. No. 20524 Field Museum of Natural History. Adult 
male. Collected Nov. 14, 1913, by M. P. Anderson. Orig. No. 159. 
Characters.—Similar in general characters to Peramys brevicaudatus 
but color of under parts entirely rich tawny; hairiness at base of tail 
reduced to about a half-inch, that of the upper side only slightly exceed- 
ing the lower; skull larger and teeth relatively small. 
Color.—Median upper parts from end of nose to rump with hairs 
dull slaty at the base and tipped with yellowish gray, the whole forming 
a broad grayish dorsal band; sides of face including a narrow line over 
the eye, sides of body, arms and legs, and entire under parts deep rich 
ferruginous; hands and feet dusky mixed with ferruginous; scaly part 
of tail blackish above and below. 
Skull.—Similar to that of P. brevicaudatus but larger; nasals long 
and broadly expanded posteriorly; naso-frontal suture emarginate; 
rather marked postorbital swellings; molariform teeth slightly smaller 
; than in brevicaudaius. 
Measurements.—Type: Total length 197; head and body 116; tail 
79; hind foot 21.5. Skull of type: Greatest length 36; basal length 36; 
zygomatic breadth 19.8; greatest interorbital breadth 7.5; least inter- 
orbital breadth 6.3; length of nasals 17; greatest width of nasals 5.8; 
palate length from gnathion 20; front of canine to back of M* 14.4; 
combined length of Ms** 6.5. 
Remarks.—This species is not only darker in color than brevicaudatus 
but the hairiness of the upper side of its tail is much less extensive. 
It is evidently larger and darker than P. b. orinoci and P. b. dorsalis
