THE GENERAL ANATOMY OF THE TARSII [SECT. A 



(e) The left lateral lobe (Fig. 70) resembles that of the 

 Lemur, for it sweeps round to the right side of the abdominal 

 cavity. 



(f) The lobus caudatus has a very distinct papillary com- 

 ponent (lobus Spigelii) which fits accurately into the lesser cur- 

 vature of the stomach, being clearly visible from the ventral side 

 when the left lateral lobe is raised. The " true " caudate corn-

ponent is shorter than in the Lemur ; it is neither falciform nor 

 uncinate as in that animal. It is partly fused with the right lateral 

 lobe (my specimen confirms this, the view of Leche, as against that 

 of Ruge 1 ). In these characters (f) Tarsius approaches the Apes. 

 On the whole, however, the liver of Tarsius is of Lemurian 

 type, and indeed, the aberrant Lemurs such as Perodicticus
