248 On some new Hast-Indian Muride. 
This fine species, which I have named in honour of Dr. 
Dammerman of Buitenzorg, is readily distinguishable by 
its thin harsh fur, very different from that of R. miillert, its 
reddish-brown colour, and long narrow skulJ. Its alliance 
would seem to be with the rattus-negleetus group, judging by 
its 3—3=12 mamme, but it does not seem very closely 
related to any described form. 
Rattus pesticulus, sp. n. 
A dwarf member of the rattus-neglectus group. 
Size very small, hardly greater than in the concolor group. 
Fur thin and coarse, not definitely spinous. General colour 
above dull reddish brown, sides rather greyer, under surface 
sharply defined white, the hairs on the throat with grey 
bases. Hands and feet white. Tail of medium length, 
thinly haired, hight brown, almost white basally. Mamme 
3—3=12. 
Skull conspicuously smaller in all dimensions than in 
neglectus, but of about the same general proportions. Supra- 
orbital beads distinct ; no postorbital projections. Palatal 
foramina to the ‘level of the front root of m'. Bulle of 
normal size, 
Dimensions of the type (measured on a stuffed specimen) :— 
Head and body 151 mm. ; tail 148 ; hind foot 30 ; ear (no 
doubt shrunk) 13. . 
Skull: greatest length 37°5; condylo-incisive length 36 ; 
zygomatic breadth 18; nasals 13 ; breadth across parietal 
ridges 14; palatilar length 18°5; palatal foramina 7:4; 
upper molar series 675. 
Hab. Menado, Celebes. 
Type. Adult female. B.M. no. 21. 2.9.11. Temporary 
number 16. Collected 1908 by Dr. Mohari. One specimen. 
This pygmy member of the rattus-neglectus group is an 
island analogue of the small S.-Indian &. r. wroughtoni and 
h. kandianus, but seems to deserve a special specific name. 
Uromys talaudium, sp. n. 
A beautiful ochraceous species, barely less vivid than 
U. fulgens. 
Size about as in fulgens. General colour above rich ochra- 
ceous, below sharply contrasted white, tle 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
