irregular longitudinal folds, not continuous with those described 
above. The epithelium here is very thick and white. Immediately 
above the pylorus the cavity is dilated on the right or great-curva- 
ture side. The opening of the pylorus is much contracted, and 
crescentic, being bounded by a strong transverse ridge rather more 
than half encircling the tube on the right or great-curvature side, 
and by an oblong very prominent valvular projection on the side of 
the lesser curvature*, which fits into the concavity of the opposite 
crescentic ridge.

The small intestine, after it was laid open, measured 9! 6! from 
the pylorus to the ileo-czecal valve. The circumference at the upper 
part was 2}", diminishing to 12! at the lower end. There was no 
trace of valvulze conniventes. The villi were abundant, especially 
near the upper part. Agminated glands commenced 2! below the 
pylorus: the first was circular (-3" in diameter); the largest was oval 
* Similar to that observed in the Pig, Manis, Armadillo, and Sloth Bear, but 
not in the Carnivora generally. It may be remarked that the stomach of Pro- 
teles, both in form and structure, closely resembles that of the Armadillos, which 
are also carrion- and insect-eaters.
