1886.] MR. 0. THOMAS ON LAGORCHESTES FASCIATUS. 547 
Finally, so far as regards colour, the transverse banding of the 
lower back presents a style of coloration quite unique in this family, 
and, beyond the Macropodide, only found among Marsupials in Thy- 
lacinus and Myrmecobius, in which, however, it is far more prom- 
inent than in the Banded Wallaby. 
The last point for consideration is the systematic position of 
Lagostrophus among the other genera of the family, and I have 
therefore compared its characters with those of the sections and 
groups into which Prof. Garrod, in his classical paper on Dorcopsis *, 
has divided the subfamily Macropodine. ‘This comparison shows 
that the differential characters of Lagostrophus are of distinctly 
greater systematic importance than are those separating Prof. Garrod’s 
Section I. from Section IT., as these appear to be by no means so 
persistent or invariable as that author supposed. I cannot therefore 
consider Lagostrophus, as a group, less than equal in value to all the 
other genera of the subfamily combined, so that the following is the 
arrangement that I would propose to substitute for Prof. Garrod’s :— 
Family MACROPODIDA. 
Subfamily Macroropinz. 
Section I. 
A. Genera Macropus, Petrogale, Onychogale, Lagorchestes. 
B. Genera Dendrolagus and Dorcopsis. 
Section II. Genus Lagostrophus. 
Subfamily HypstpRYMNIN2. 
Section I. Genera Hypsiprymnus, Bettongia, depyprymnus, 
Subfamily HyesipRyMNODONTINE. 
Section I. Genus Hypsiprymnodon.
