In the British Museum collection arc three specimens 1 agree¬ 
ing with the abovo description ; of one of these, the largest, I 
have given the dimension in the second column, those of the 
first column being from a specimen in Mr. Gould’s collection. 
A skull removed from one of the Museum specimens is some¬ 
what fractured, and in the first of the admeasurements given 
below, allowance has been made for the lost, occipital portion.

According to Mr. Gould, the D. concinna is abundantly, 
and very generally distributed over the colony of Swan River. 
Its habits being strictly nocturnal, it secretes itself during the 
day in the hollows of trees, and at night leaves its retreat for 
the flowering branches of low shrubby trees. At that time it 
is said to be very active, and when kept in confinement will 
leap from side to side of its cage in chase of insects, of which 
it is exceedingly fond. The sexes present but little difference 
either in size or colouring; in some specimens the under 
parts of the body are slightly tinted with buff colour.
