58 MR. A. H. GARROD ON HALMATURUS LucTUosuUS. [Feb. 2, 
of the Macropodidee which have come before me in my study of 
Dorcopsis luctuosa would lead me to divide up the family in the 
following manner :— 
Family MACROPODID. Diprotodont Marsupialia wanting the 
hallux, the second and third digits of the pes being much re- 
duced and included in the skin as far as the ungual phalanges, 
which at the same time have the claws so formed that the inner 
is convex inwards and the outer convex outwards, at the same 
time that their contiguous surfaces are flattened. The stomach 
is elongated and sacculated. 
Subfamily Macrorop1n#. Macropodide in which the ceso- 
phagus enters the stomach near the cardiac end; witha Spi- 
gelian lobe to the liver; with no lateral longitudinal bands 
to the colic ceecum when it is short, and with radius of nor- 
mal form. 
Section 1. Macropus. With the premolars never much 
larger than the first molar; with a characteristic molar 
tooth-pattern ; with the stomach but slightly lined with 
digestive epithelium (?) and with the hair on the nape of the 
neck directed backwards. Hab. Australia, Tasmania, 
Aru, and the Ké Islands. 
Genera or subgenera. Macropus, Halmaturus, Petrogale, 
Lagorchestes. 
Section 2. Dorcopsis. With the premolars strikingly large, 
with a characteristic molar-tooth-pattern, slightly modi- 
fied upon that of Macropus; with the stomach mostly 
lined with digestive epithelium, and with the hair of 
the nape of the neck directed forwards. Hab. New Guinea 
and Mysol. 
Genus 1. Dorcopsis. Limbs Macropine in their proportions. 
Genus 2. Dendrolagus, Protemnodon*, Sthenurus*. Fore 
limbs much longer than in Macropus. 
Subfamily HypstprymMNinz&. Macropodide in which the 
cesophagus enters the stomach near the pyloricend ; with no 
special Spigelian lobe to the liver; with lateral longitudinal 
bands to the short colic cecum; with a much-flattened and 
expanded radius, with a characteristic molar-tooth-pattern, 
and with the incisors worn down much as in Rodent animals. 
Hab. Australia and Tasmania. 
Genus Hypsiprymnus (including H. murinus, H. gilberti, 
and H. platyops). Auditory bulla somewhat inflated ; 
palatine foramina, one large one on each side ; ridges on 
premolars few and perpendicular. Face elongate. 
* An inspection of the plates in Prof. Owen’s paper on these new genera 
(Phil. Trans. 1875, p. 245), makes it evident that they are scarcely distinguish- 
able from Dendrolagus, and must be included in the Dorcopsts section of the 
family.
