 kamichis, the water fowls, sea partridges, and 

 flamingos. Some have very long and slender 

 claws, which enable them to walk on marshy 

 ground, and support themselves on the grass; 

 others have their feet furnished with mem- 

 branes, often dentated, which facilitate their 

 swimming. They form the passage from the 

 gratlcG to the palmipedes. Thirty species of rails 

 furnish the lower shelves of the forty -fifth case-
