298 MR. E. T. BENNETT’S ACCOUNT OF MACROPUS PARRYI. 
swiftness ; and it was curious to see it bounding up a hill and over the garden fence, 
until it had placed itself under the protection of the dogs belonging to the house, espe- 
cially of two of the Newfoundland breed, to which it was attached, and which never 
failed to afford it their assistance by sallying forth in pursuit of its adversaries.” 
Captain Parry further observes, that, ‘like all other Kangaroos, this animal, when in 
active motion, never touches the ground with its tail, merely using it to form a tripod 
when standing erect. It seems to inhabit no part of the colony in the latitude of Sidney.” 
On his return to England Sir Edward Parry brought the animal with him ; but soon 
after his landing it met with an accident by which its leg was broken, and which it 
survived for only a short time. Its body was presented to the Society while yet recent; 
and the following account of the particulars observed in its dissection is by my friend 
Mr. Owen. 
** Having examined, at the request of my friend Mr. Bennett, the principal viscera of 
this new species of Macropus, I find that they present with few variations the same 
characters which belong to the anatomy of the greater Kangaroo, and which have been 
for the most part described and figured in the works of Home and Cuvier. 
‘“«The large sacculated stomach occupied the epigastric, left hypochondriac, and left 
lumbar regions ; from this it passsed obliquely upwards and across the abdomen, and 
then turned, as in the greater Kangaroo!, to terminate in the duodenum. The cardiac 
end was produced into two small sacculi, which were not so much separated from each 
other as in Macr. major, but were folded back upon the stomach. The cardiac extre- 
mity was situated sternad of the wsophagus, which was about 3 inches long after passing 
the diaphragm. The interior of the stomach presented the same disposition of cuticle, 
and series of glandular patches, and the pylorus was surrounded by the same thickened 
zone of glands, as in Macr. major. The sacculi were puckered up by two longitudinal 
bands extending from the esophagus along either side of the smaller curvature, while 
in Macr. major a third longitudinal band extends along the line from which the great 
epiploon is continued to the spleen and transverse colon. 
*“« There were two hair-balls in the stomach, of an oval shape, not rounded as they 
generally are in the Ruminants, which are most obnoxious to these formations. One of 
these hair-balls measured 3 inches in the long diameter; the other, 2 inches. They 
were entirely composed of the hairs of the animal, matted together and agglutinated 
by the mucus of the stomach. ‘This occurrence of an inconvenience which is the oc- 
casional result of a necessary complication of the principal digestive organ, is interesting 
on account of the near approach to the Ruminating tribe which the Kangaroos make 
in the complexity of the stomach, and which is united with a corresponding simplicity 
of the cecum and colon. 
‘«T have more than once observed the act of rumination in the Kangaroos preserved 
in the Vivarium of the Society. It does not take place while they are recumbent, but
