South-American Monkeys, Bats, Sc. 463 
yellowish suffusion characteristic of G. vittata, rather than 
the clear greyish of G. Allamandi. 
Skull about as in G. Allamandi, smaller than in the large 
Brazilian form described by Nehring as G. crassidens. 
Nasals evenly narrowing backward and pointed behind, not 
abruptly narrowing from a broad point at about two thirds 
their length, as in the Central-American form. Last upper 
molar with a posteriorly broadened inner lobe, almost as in 
the Martens (Justela), and in this respect quite unlike that 
of any other Galictis. 
Dimensions of the type :— 
Head and body 540 millim. ; tail 160; hind foot, s. u. 75, 
Gu. 78. 
Skull: greatest length 85; basilar length 76; greatest 
breadth 49 ; interorbital breadth 19; mastoid breadth 46 ; 
palate length from gnathion 41. ‘l’eeth: upper incisor-row 
11; outer length of p* 9:5; transverse length of m' 7:8; 
longitudinal diameter of inner lobe of m* 5:1; length of 
m, 10.

This Galictis differs both in colour and tooth-structure 
from the other members of the group. Its yellower colour is 
markedly different from that of two examples from Chiriqui 
(Watson) which I assign to G. Allamandi, and think also 
represent Nelson’s G. canaster. Nehring’s G. crasstdens, on 
the other hand, appears to be a larger animal, as is shown by 
the greater dimensions of the teeth, and comes from a 
very different locality. Finally, the broadened inner lobe to 
the upper molar is quite unique in this genus and recalls the 
corresponding tooth in Galera. 
Sciurus Roberti, sp. n. 
An olive species related to S. Ingrami and gilvigularis. 
Size, as gauged by linear measures, almost equal to that of 
S. Ingram, but the animal is more lightly built, and the hands 
and feet in particular are markedly more slender. Fur 
throughout much shorter than in Jngram2, more as in gilvi- 
gularis (hairs of back only 6-7 millim, in length), that of 
ears, feet, and tail all shortened, in agreement with that of 
the body. General colour above olivaceous, varying from 
yellowish olivaceous to greyish. Under surface not sharply 
defined, white or whitish on the throat, inner sides of limbs,
