274 PROF. ST.-GEORGE MIVART ON THE [Feb. 21, 
concave side of and close to the flexure of the pylorus, on the 
cardiac portion of the stomach. The cardia is largely developed, 
extending 4!"5 beyond the entrance of the cesophagus. The 
stomach of this species is much longer relatively than that of 
Hystrix javanicus, and it differs from the stomach of that species in 
having no sacculus between the cardia and pylorus. 
Length of the stomach, measured along its middle, in its naturally 
Exterior of the excum of Hrethizon dorsatus. 
1.2, large intestine ; s.2, small intestine. | 
curved condition, 26''-6 ; vertical diameter of stomach at entrance 
of cesophagus 7''"6 ; its diameter at pyloric flexure 7'-6, from pyloric 
valve to entrance of bile-duct 3/3, from entrance of bile-duct to 
that of pancreatic duct 2!'-5. 
The general arrangement of the intestine appeared to correspond 
closely with that found in the Guinea-pig,—folds of large intestine 
being arranged immediately behind the stomach and right segment
