8 NOTE ON THE VISCERA OF TARSIPES. 
though of no great size, is to be found. Though there is perhaps not yet sufficient 
reason for constituting Tarsipes the type of a separate family, yet the characters of 
the stomach further strengthen the reasons already known (of which the most 
important perhaps is the absence of a czecum) for separating it in a sub-family from 
the other genera of Phalangeridee. 
The liver is deeply cleft, and the left lobe is much the smaller of the two. The

left lobe is not divided, or at most by a mere rudiment of a fissure. The right 
central lobe is divided by a great cleft and furrow, which lodge the gall-bladder in 
its upper part. The Spigelian lobe and caudate lobe, especially the latter, are 
extremely large. In Phalangista vulpina, on the other hand, the left lobe is very

relatively much larger, and the left half of the right central lobe has increased 
greatly at the expense of the other; the Spigelian lobe is very small indeed, and 
the caudate lobe small, narrow, and elongated. The liver is so variable in its 
details of form among the Marsupials that its minor characters have little value in
