12. Uromys talaudium, THOS. 
A beautiful ochraceous species, barely less vivid than U. fulgens. 
Size about as in fulgens. General colour above rich ochraceous, below sharply 
contrasted white, the hairs white to their bases. Body-fur extending on to base of tail 
for more than half an inch. Hands and feet white. Tail long, nearly as long as in fulgens, 
uniformly pale brown. 
Skull about the same size as in fulgens, but not so heavily built, less convex above, with 
‘narrower interorbital space, narrower brain-case, and longer, less open palatal foramina. 
Palate slightly broader, the two molar series less strictly parallel, more divergent behind. 
Dimensions of the type (measured on a skin):— 
Head and body 145 mm.; tail imperfect (in another similar-sized specimen 190); 
hind foot 31. 
Skull: greatest length 39.5; condylo-basal length 37.8; zygomatic breadth 21; 
nasals i3; interorbital breadth 6.2; palatilar length 18.4; palatal foramina 6.3; breadth 
across outside m? 8.8; upper molar series 7.3. 
Hat. Talaud Islands, between Gilolo and Mindanao. Type from Liroeng. 
Type. Adult female. B.M. no. 21. 2, 9, 3, Temporary number 24. Taken by the 
Controleur 13th April, 1916. Presented by the Buitenzorg Museum. f 
(Ann. and Mag. of Nat, Hist. Ser, 9, Vol. VII, March 1921, p. 248.) 
The discovery of two species of Uromys in the Talaud Islands greatly 
extends the known range of the genus, the nearest localities to this as yet 
reported being the Obi Islands and Salawatti. No doubt the group will 
prove also to occur in Gilolo. 
The present species is shown by its long tail to be an arboreal animal, 
and I have little doubt that, like U. fulgens, which it nearly resembles, it 
purchases safety from predaceous birds by its striking resemblance in colour 
to the mantle of the large species of Pteropus. 
Local observations are needed for the confirmation or disproof of this 
theory, which was advanced on the description of U. fulgens. 
13. Uromys caurinus, sp. n. 
J 23. 2. 40.98 (juv). Talaud Islands. 
A medium sized short tailed species of the U. bruïfnit group. Size about as in the 
larger ordinary species of Uromys, exclusive of the giant species; build robust. 
General colour above near cinnamon brown, paler on the sides. Undersurface white, the 
hairs white to the roots; on the belly the white only covers a breadth of about an 
inch, but is broader on the chest and inguinal region, Ears as usual short. Hands and 
feet whitish above, inner side of limbs white. Tail shorter than head and body, pale 
brown throughout. f 
Skull stoutly built, with well marked divergent supraorbital ridges. Nasals extending 
well behind the anterior corner of the orbits. Palatal foramina quite short, much 
shorter than in the Ceram species. Molars stout and heavy. Posterior edge of palate 
level with the front of m°. Bullae small. 
Dimensions of the type, measured on the remade skin: — Head and body 176 mm; 
Tail 137 mm.; Hindfoot 30 mm.; ear 15 mm.; Skull greatest length 39 mm.; condylo- 
incisive length 37.2; zygomatic breadth 30.2; interorbital breadth 6.7; breadth of brain 
case between parietal ridges 14.8; palatilar length 17.8; palatal foramina 5.4 X 2.6; 
breadth of mesopterygoid fossa 3.2; upper molar series 8. 
Hab. as above. 
Type. Old female. B.M. No. 21. 2. 9. 2. Temporary number 40.
