Salivary glands.—These glands in the Car- 
nivorous Dasyures consist of a small parotid 
and a large submaxillary gland on each side. 
I searched expressly, but in vain, for the zygo- 
matic gland; the Dasyures do not agree with 
the dogs in having these glands. They have no 
sublingual gland. The submaxillary gland is 
placed in front of the neck, so that its duct passes 
on the dermal side of the tendon of the biventer 
maxille, and terminates half an inch from the 
symphysis menti. There is a thick row of 
labial glands along the lower lip. The Opos- 
sums and Bandicoots present a similar salivary 
system. 
In the Phalangista vulpina there is a sub- 
lingual gland on each side of a firm texture, 
about one inch in length and three lines broad ; 
a roundish submaxillary gland about the size 
of a hazel-nut; and a broad and flat parotid, 
larger than in the Entomophagous or Sarco- 
phagous Marsupials. 
The parotid glands are relatively larger in 
the Koala, in which the duct takes the usual 
course over the masseter and enters the mouth 
opposite the third true molar, counting back- 
s. 
In the Wombat I found the parotid glands 
very thin, situated upon both the outer and 
inner side of the broad posterior portion of the 
lower jaw; the duct passed directly upwards 
and outwards to the insertion of the sterno- 
cleido-mastoideus ; here it was buried in the 
cellular substance anterior to that muscle, then 
turned over the ramus of the jaw, and, pur- 
suing a somewhat tortuous course over the 
masseter, entered the mouth just anterior to 
the edge of the buceinator. The submaxillary 
glands were each about the size of a walnut; 
their ducts terminated as usual on each side of 
the freenum lingue. 
* These admeasurements were obligingly com- 
municated to me by my friend Mr. Hobson, of 
Hobart Town, Van Dieman’s Land, and were taken 
from an animal killed in the wild state. I subjoin 
the admeasurements of an individual of the same 
species which died after a year’s confinement in the 
Zoological Gardens: there is a considerable diffe- 
rence in the length of the intestinal canal and 
= 
In the great Kangaroo the parotid is v 
large, extending from below the auditory me 
tus three or four inches down the woot | 
the Hypsiprymnus it reaches as far as the els 
vicle. In both cases this gland is separate 
from the submaxillary gland by the su 
lary vein. hy 
The tonsils are small in all the Marsupial: 
but are not represented in the carnivorous spi 
cies, as in the Placental Fere, by simple glan 
dular pouches at the sides of the fauces; for 
example, they consist of an oblong glandula 
body on each side in the Dasyurus macrurus. 
The liver—The liver is subdivided i 
many lobes in all the Marsupial genera. It is 
relatively largest in the burrowing Wombat 
and carnivorous Dasyure; relatively smallest 
in the graminivorous Kangaroo, in which it is 
situated, as in the placental Ruminants, en- 
tirely to the right of the mesial plane. The 
small or Spigelian lobe, which tis into 
lesser curve of the stomach, is given off 
the left lobe of the liver in the Kangaroos, but 
from the right in most other Marsupials ; the 
difference just noticed in the Kangaroo de 
on the peculiar disposition of its rem: 
stomach. > 
In the Koala the under surface of the liver 
(fig. 130) is singularly sculptured and subdi- 
vided into thirty or forty l-bules; this condition 
is presented in a minor degree in the liver of th 
Ursine Dasyure. a 
In a long-tailed Dasyure, which weigher 
3 Ibs. 8} 0z., the liver weighed 3} oz. avoir 
dnpeiee. ; 
he gall-bladder is present in all the Marsu- 
pials, and is generally of large size and loosely 
odged in a deep cleft of the cystic lobe. In 
the Opossum it generally perforates that lobe, 
and the fundus appears at a round opening on

especially of the cecum; and it may be alle 
to speculate upon the influence which differ 
of diet and confinement may have had in prod 
this difference. Mr. Martin’s admeasurements of 
another Phal. Vulpina agree more nearly with mine.
