intestine is contained from nearly 8 to 10 times in the length of the small intestine. 
The paracecal loop is also lacking according to TULLBERG.! 
Uromys littoralis n. sp. A female caught under a board on the beach near 
the mouth of Russel River, Northern Queensland the 9th of May 1913, and its two 
young ones. 
This rat is probable related to M. cervinipes, of which it may be a dwarfed 
littoral race. It differs, however, very plainly in being much smaller and slenderer 
in every respect and by this resembling those small Uromys-forms which THOMAS has 
described not long ago viz. U. melicus from Melville Island, U. lutillus from Owgarra, 
S. E. Brit., New Guinea, U. murinus from Murray Island, Torres strait, and U. 
muscalis from Lower Fly River, Brit. New Guinea. 
It appears to be as small as any of these. The general colour is on the sides 
most similar to RiIGDWAY's »drab>, somewhat suffused with buffish, on the back 
darker, more brown by means of the blackish brown tips to the hairs. On the flanks 
the colour of the lateral parts passes gradually into the light buff of the lower side 
which exactly corresponds to »buff, 309,1> of Dauthenay: Rép de coul. The throat 
is yellowish white. The feet are scantily covered with whithish hairs. "Tail wholly 
dark. The fur is soft and dense, about 11 mm. long, basally it is slate grey on the 
upper side, plumbeous grey on the lower. The scales of the tail rather small so that 
18—19 rings may be counted to the centimetre. 
Head and body (skin) about 90 mm. ; tail a little longer, about 112 mm. Hind 
foot dry (s. u.) 26 mm. (ce. u. 27,8).

From U. melicus THOMAS the present form differs by its decidedly smaller size 
as well with regard to body, tail and hind foot as to skull measurements. U. muri- 
nus and muscalis differ by white lower parts, the latter has also much smaller teeth, 
while the present form has rather larger teeth even than U. murinus and lutillus. 
The last mentioned is to judge from the description most similar to U. littoralis, but 
appears to have larger scales on the tail, smaller feet and teeth. This together with 
the geographical isolation of the two animals make me regard them as different.
