6 EINAR LÖNNBERG AND ERIC MJÖBRRG, DR. E. MJÖBERGS EXPEDITIONS TO AUSTRALIA. 2. MAMMALS. 
About this specimen as well Dr. MJÖBERG writes in his diary that the two 
young ones remained attached to the teats, although the mother ran hither and 
thither on the beach for a while before she was caught, and the young were dragged 
along on the ground. The young are hairy and represent about the same stage as 
those of U. cervinipes mentioned above. Length of head and body about 45 mm., 
tail about 35 mm. As already has been reported above to be the case with the young 
of U. cervinipes the mouth is open and appears quite normal. It is not obliterated 
at the sides as in the marsupials for the retaining of the maternal nipple. Itis thus 
evident that the young animal in the present case has the faculty of holding on to 
the teat of the mother by means of their own muscular strength and with the aid 
of their jaws, lips and teeth. I think that it is especially the latter which are import- 
ant in this case as the chief implements. But they are naturally enough, not worn to 
chiselshaped edges at the ends, in which case they would wound the mother, on the 
contrary they are, especially those of the upper jaw, blunt. The upper incisors are 
also a little diverging with their bluntly rounded extreme ends, and by this, no 
doubt, the young animal gets a firmer grip. 
A similar observation concerning another Australian Rodent viz. Coniluwrus 
albipes LiCHTENST. has been recorded by DoUGLAS OGILBY (Cat. of Austr. Mam. p. 
114). It is a remarkable biological fact which thus now has been discovered within 
another Murine genus, but there is, of course, no the slightest trace of any marsupial 
affinity indicated by this. 
Epimys assimilis GouLp. One specimen from the interior of a rain-forest jungle, 
Millaa Millaa, N. Queensland, !?/2 1913, another from the same locality '?/a 1913, and 
a third from Cedar Creek, N. Queensland, ”/« 1913. The last specimen was taken 
»from a nest of leaves under a fallen tree trunk>. 
All specimens are flat skins (in rather bad condition) with skulls. 
Epimys chionogaster n. sp. A rather large rat with the fur above long and 
close, rather harsh to the touch. The general colour above rich buff, overlaid with 
very long black hairs. The fur is grey at the base. The long hairs attain a length 
of 30 mm., the others about 15 or less. The long hairs are flattened at the base 
but not at all spinous. The sides of the body and the outer side of the legs more 
sandy grey, gradually becoming lighter down on the flanks, but nevertheless with a 
sharp line of demarkation towards the pure white lower side of body and inside of 
limbs. This white area is continuous from the chin to the vent, and the hair are 
also white at the base. Feet creamy white with very sharp line of demarkation. 
Whiskers very long and numerous, black. Tail with about 230 rings of scales and 
with short (not two rings in length basally) blackish hairs, which are a little more 
numerous towards the tip. About 10(—11) rings of scales to the centimetre at the 
base of the tail and at the middle of the same. Ear almost naked, broadly rounded, 
about 20 mm. (dry). Hind foot with 6 pads.
