the cardiac division is thin, that of the pyloric end thicker. The inner coat of the form

they are well marked, though not very numerous. Some three or four narrow, forked 

 hut sweeping folds exist within the surface of the lesser curvature and right moiety of 

 the posterior^wall, reaching from the oesophageal aperture towards the pylorus. Several 

 others of a similar kind well nigh at right angles to the former, floor the great curva- 

 ture. The thickening of the pyloric parietes is due to increase of the submucous and 

 muscular coats, besides the additional free mucous folds. To the naked eye the mucous 

 membrane appears almost smooth ; but with a hand-lens many apertures of gastric glands 

 are visible ; and between the latter the character is finely villous. 

 The small intestines are 52 inches long, and with a nearly uniform diameter of about 

 of an inch thouo^hout! A fair-sized Peyer's patch lies within a } of an inch of tlie

pylorus ; and others are met with at wide intervals. Valvulte conniveutes are wanting. 

 A nipple-like process, 1 inch from the pyloric ring, marks the aperture of the pancreatic 

 and common bile-duct. There is no cjecal diverticulum, nor ileo-csecal valve. The divi- 

 sion between ileum and colon is indicated by an enlargement of the latter. Near its 

 commencement, where widest, this simple colon is no more than an inch in diameter; 

 and it narrows steadily for a distance of 5 inches or more, the last 3 inches (or what 



r ,1 



corresponds to rectum) again widening. The entire length of the great gut is 

 9J inches. 



In the stomach being less round, the cesophagus more to the right, absence of 

 pyloric division, no valvular protuberance (although the pylorus is thick, and orifice 

 narrow), Toli/peiites coincides with the six-banded species of Dasypits and Chlamy- 

 dophoms, and not with the Peba {Tatusid), But in deficiency of a pair of short csecal 

 appendages it agrees with the latter, and differs from the two former \ Again, the 

 gut is altogether very much shorter than in either genera compared. 



The thick bifid spleen, with free limbs of unequal length, is firmly adherent, by a short 

 gastro-splenic omentum, to the lower left end of the stomach. It is less than a couple 

 of inches in extreme length. Owen ^ mentions that this organ is broader and flatter in 

 D.sexchictus than in J), (Tatusia) peba; and in the former he observed that "asmaU 

 supernumerary spleen was lodged in the head of the pancreas." In my own dissections 

 of these animals, with shght difference of size, no variation obtained from Tolypeutes. 



The pancreas is also thickish, but flat, nodulated, and H in. in diameter. -
