92 Mammalia, Digestive System. 



the Murida, SciuridcB, and Hystricidce of the Eodentia [cf. Teeth) ; 



most Digitigrade and Pmnigrade Sectorialia, especially in the 

 typical Eelidee, e.g, Leo [being longer in Hyaena than in Leo, and 

 again longer in Canis than in Hyaena] ; 



all Artiodactyla ; 



all Sirenia [that of Manatus being bifid] ; 



the Entomophagous Marsupialia, and all Marsupials that have a 

 saccnlated Stomach ; 



and the Monotremata [that of Echidna being vermiform and 

 glandular]. 



is long, wadi frequently sacculated m 



all LemuridcB, or Strepsirrhine Quadrumana [in Cheiromys, and 

 Stenops Javanicus, it contracts at its termination, and becomes 

 glandular] ; 



many Rodentia [in Eathyergus (Mole Rat) and Arctomys (Mar- 

 mot) the inner membrane of the Caecum is augmented by transverse 

 or circular folds. In Coypu the Caecum is puckered into sacculi by 

 two muscular bands. In Capybara the enormous Caecum occupies 

 almost the whole of the posterior half of the abdomen. In most 

 vegetarian Eodentia the Caecum is long, especially so in the Leporidae. 

 Two oval patches are usually found on either side of the ileocaecal 

 valve. In the Leporidae the termination of the Caecum is slender 

 and glandular, like the vermifonn appendage in Man] ; 



the Frohoscidia, in which the large Caecum is sacculated on three 

 longitudinal bands ; 



the Perissodactyla [in Equus Caballus the Caecum is sacculated on 

 four longitudinal bands ; but in Rhinoceros on a single broad band 

 on the anterior surface] ; 



the Balmno]ptera (Cete) ; where the Caecum, though simple, is of 

 considerable length ; 



and in the Carpophagous Marsupials [the Phalangers having a 

 Caecum sometimes twice the length of the body ; the Koala having 

 a Caecum three times the length of the body, with its inner secreting 

 membrane further augmented by several nearly parallel plaits, con- 

 tinuing from the Colon three-quarters of the way towards the blind 

 extremity], 



has a Vermiform Appendix in 

 JBimana ;
