Well developed lateral ridges or beads, especially strong in the frontal portion, 
but also distinet in the parietal. Interparietal bone rather broadly semilunar with 
the anterior border straight. First upper molar similar to that of KE. rattus with 
distinet outer tubercle on first lamina. 
To the exterior this rat appears to resemble to some degree Epimys villosissi- 
mus WAITE, but differs from the same by the pure white lower side, in having the 
tail longer than head and body and in having larger skull measurements, except that 
the palatal foramina and the upper molar series are shorter. WAITE says also about 
Epimys villosissimus that the skull is »very similar to that of Mus decumanus» while 
the present rat has a skull strongly resembling that of £. rattus. It is so rattus-like 
indeed that it almost appears questionable whether it is a geographical variety of 
the same or not. 
The type is a male specimen collected at »Tolga, Northern Queensland, in open 
forest land>.
