Abstract:The author observed the intestine, liver and pancreas of R.roxellanae. The whole length of the intestinum tenue was about 284.0 to 296.0 cm, the duodenum, about 9.0 to 12.0 cm, the remainder was the length of the jejunum and ileum. The duodenum presented V – shaped. The length of intestinum crassum was about 120.0 to 130.0 cm. There was no appendix vermiformis. The length of the colon ascendens was only about 7.0 to 8.0 cm; that of the colon transversum, about 19.0 to 20.0 cm and the length of the colon descendens and the colon sigmoideum, about the 80.0 to 90.0 cm. The liver of the R. roxellanae consisted of the dorsal part and ventral part. The ventral part included the superior part and the inferior part. The ductus choledochus entered the pars superior duodeni. The pancreas was like T – shaped. The caput pancreatis was surrounded by the pars descendens and the pars ascendens of the duodenum. The pancreatic suct opened into the pars ascendens of the duodenum, which passed through the caput pancreatic. Besides, the difference among the individuals, the relative factors of the developing of the caecum and colon and the relation between the fusion of the lobes of the liver and the evolution were discussed.
