classification. or instance, among the Phalangistinee, Cuscus* has a liver in which, 
as in Phalangista, the left lobe is very large and divided, and the right lateral lobe 
is small ; but in which, on the other hand, the Spigelian lobe is large and trilobed, 
and the caudate lobe, in comparison, very small. 
The long pointed tongue bears three cireumvallate papilla, the posterior very

large, and all three circular and symmetrical. The angle formed by the posterior 
with the two anterior papille is acute. Unlike the tongues of the Phalangistidee 
described by Pouuron,t the anterior as well as the posterior papillz: are radially 
symmetrical. The greater part of the dorsum of the tongue, within the limits 
shown in the figure, is covered with very long compound filiform papille of the 
“coronate” type, now well known through Pounton’s researches as characteristic 
of the Marsupialia. I have sought for the lateral organ and cannot find it. Its 
apparent absence may be due only to the state of the specimen ; but I am sure that 
if it be present at all, it will be found to be small or rudimentary.
