angular with the apex formed by the oesophageal orifice. The 

 left rounded basal angle represents the fundus, and the duo- 

 denum joins it at the right one. The pylorus does not project 

 into the duodenum, and the sphincter is weak. The fundus is 

 rugose. ISTo gastric gland is present as in Ccenolestes (9), but 

 there is a small lymphatic gland on the lesser curvature.

 difiers from the above in the thickness of the pyloric region, the 

 existence of well-marked rugae on both walls, and the great 

 strength of the pyloric sphincter. There is a small lymphatic 

 gland on the lesser curvature as in Perameles obesula.
