have been impregnated. When they were first brought to this 
country there was a very obvious difference in the state of the 
pouches. The teats, which are four in number, were much 
larger in the elder specimen, particularly the two anterior ones ; 
which is directly opposite to the state of these organs in the 
Kangaroo, as described in the valuable and elaborate paper of 
my friend Mr. Morgan, lately read before the Linnean Society. 
At the present time, however, the teats in the two specimens 
are nearly, if not exactly, of the same size,—an interesting cir- 
cumstance, as indicating an analogy to these organs in the 
Kangaroo; in which animal, as shown in the paper just referred 
to, a similar diminution of the teats takes place after the young. 
have finally left the pouch. - The cloaca is placed about one- 
third of the distance from the root of the tail to the pouch. | 
On examining the characters of this interesting and elegant 
little animal, it is impossible not to be struck with its general 
approach to the Petauriste,—a resemblance to which I have 
already alluded. "The identity of many of its more obvious 
characters with those of Phalangista nana is too marked not to 
demand a particular investigation. The history of the latter 
species is but very imperfectly known ; indeed, the short and 
necessarily unsatisfactory account given by the celebrated 'l'em- 
minck in his Monograph of this genus, serves only to raise our 
curiosity, without affording an opportunity of satisfying it. The 
small size of that species, being not larger than a mouse, to- 
gether with some general similarity in the colour and marking, 
would almost lead us to identify them as one and the same spe- 
cies, were it not for one striking character, which cannot be 
mistaken, namely, the surface of the ears. ‘The description of 
Phalangista nana, as given by the above-mentioned distinguished 
zoologist,
