REPORT ON ZOOLOGY, MDCCCXLIl : 
species, without bristly hairs ; in Nos. 3-5, the tail is longer than the 
body, in Nos. 6, 7, shorter ; 3. D. incana, Lund ; pure grey above, 
beneath white ; a greyish-black band through the eye ; tail light brown, 
towards tip whitish, naked to the root; ears grey. Very ditferent 
from D. cinerea, Temm. ; body 4" ; tail 5" : 4. D, murina, Auct. ; 
5. D. pusilla, Desm. ; only portions of the skeleton, which point to 
Azara’s Enano (?) : 6. D. tricolor, in size and colour quite agreeing 
with Azara’s Colicorto, but the colour of the sides, which he calls a lively 
cinnamon hue, is, in the living species, merely ochre-yellow, on which 
account, Lund places it with doubt with the D. tricolor : 7* D. trilineata, 
described by Markgraf as a Shrew-mouse. 
J. E. Gray has increased the genus Phascogale with two new species. 
The one he names Ph. apicalis, in size and appearance resembling the 
Ph. minima, but ditfering in having long white tips to the dark brown 
and black hairs ; in the short conical tapering tail, covered with longish 
yellowish-tipt hairs, but chiefly in having a terminal pencil of black-tipt 
hairs. In the upper jaw were found only two false grinders, probably 
in consequence of its youth : Habitat unknown. (Ann. ix. p. 518). 
To the other species. Gray gives the name Ph. leucopus ; fur grey, 
washed with blackish ; head rather redder ; lips, chin, throat, chest, and 
belly, inside of legs and feet, white ; tail slender, under half white, upper 
blackish brown ; ears large. Easily distinguished from Ph. leucogaster 
by its white feet. (Ann. x. p. 261.) 
Besides these, Mr. Gould has increased the already great number of 
species of Kangaroos by six. (Ann. ix. p. 345 ; x. p. 1.) These species 
are called — Osphranter antilopinus, 0. (?) Isdbellinus, Halmaturus 
agilis. Macropus ocydromus, Lagorchestes conspicillatus, and L. albi- 
pilis. Osphranter is a newly established genus or sub-genus, founded 
on the great extension of the nasal fossas and muzzle, the proportionably 
small size of the lateral toes of the hind-foot, and the great development 
of the middle toe, &c. It is unnecessary to enter more exactly into 
this at present, as Gould will farther illustrate these species in his 
monograph. 
RODENTIA. 
Waterhouse, induced by my Treatise on the Systematic 
Grouping of the Rodentia, has begun the correction of his 
arrangement in opposition to mine. (Ann. of Nat. Hist. x. 
p. 197.) 
As we both commence from different principles, so it follows that the 
grouping of families must often be different. Waterhouse places great
