■equally common in Torres Straits. Mr. Bruce sends us the 

 following note about their distribution: — "'No.2{Enhalus Koenigii) 

 is recognised by the natives here as the true food of the Dngong;

 Both plants are found only in small patches around the Murray 

 Group, consequently Dugong is scarce; but at the islands to the 

 west of here, where the Dugong is plentiful, both plants are 

 found in profusion."
