^Eluroidea) of the anatomy of the soft parts of the Genet may be 

 given as illustration of these parts in the Carnivora generally, and 

 of this family and genus in particular. The salivary glands are 

 shown in Fig. 19 (p. 56), and these conform to the general type 

 prevalent in the 

 ^Eluroidea. Thus 

 there is a distinct 

 zygomatic gland ; 

 the parotid with 

 its (Steno's) duct 

 is well developed ; 

 and there is a 

 small submaxil- 

 lary gland. The 

 stomach (Fig. 

 234), while con- 

 forming to the 

 simple type char- 

 acteristic of the 

 Carnivora, is 

 much larger than 

 in the Cat ; it is characterised by the presence of some strongly 

 marked internal folds near the pyloric extremity, which stop sud- 

 denly at a point where the stomach makes an abrupt constriction 

 and flexure. Beyond this point there are three other longitudinal 



folds ; and the pyloric valve is 

 small. The allied genera present 

 modifications from this form of 

 stomach. The caecum (Fig. 

 235) is short, thick, and 

 pointed. The liver (Fig. 236) 

 much resembles that of the 

 Cat, but differs in that the left 

 lateral lobe is undivided, al- 

 though having a small groove 

 on its posterior or abdominal 

 aspect, while the cystic fissure 

 is less deep, and situated more 

 to the right. The caudate lobe 

 is relatively longer, has a deep 

 concavity, and runs uninter- 

 ruptedly into the Spigelian; 

 the latter being relatively somewhat larger than in the Cat, 

 with a deep groove dividing the proximal third from the distal 

 two-thirds. In Viverm the right lateral and right central lobes 

 are nearly equal in size. The variations in the form of the liver
